Recreational Use Attainability Analysis for Little Cypress Bayou Chapter 1 Introduction

Chapter 1 Introduction

Problem Statement

Little Cypress Bayou (0501B) is an unclassified water body identified for assessment purposes by the Texas Commission on Environmental Quality (TCEQ). Little Cypress Bayou is approximately 8.5 river miles long and is defined in the 2012 Texas Integrated Report of Surface Water Quality (TCEQ, 2012) as being located from the confluence with the Sabine River to the headwaters west of Reese in Orange County (Figure 1.1). Three assessment units (AUs) have been established by TCEQ for Little Cypress Bayou (0501B). The lower 4.2 miles of Little Cypress Bayou has been designated as AU 0501B_01. The section of Little Cypress Bayou located 0.3 miles upstream to 0.5 miles downstream of Bear Path Road in Orange, Texas has been designated as AU 0501B_02. The third AU is described as the upper 3.2 miles of the bayou and is designated as 0501B_03. All three AUs within Little Cypress Bayou (0501B) were first listed on the Texas 303(d) list as impaired for bacteria in 2006 and have continued to be listed as impaired for bacteria in the 2008, 2010, 2012, and 2014 Texas 303(d) lists. Additional impairments for Little Cypress Bayou include water toxicity, depressed dissolved oxygen and an impaired fish community. Water toxicity is based on chronic ambient toxicity texts that was first listed in 2004 for all three AUs and continued through subsequent Texas 303(d) lists. Depressed dissolved oxygen was identified within all three AUs and first listed on the 2006 Texas 303(d) list and subsequent lists. The 2014 Texas 303(d) has also listed AU 0501B_02 as having an impaired fish community. It should be noted that toxicity in water, depressed dissolved oxygen, and impaired fish community are parameters used in assessing a water body’s aquatic life use rather than recreational use, and therefore are not addressed in this study. The Texas Integrated Report of Surface Water Quality1 includes the Texas 303(d) list of impaired water bodies and is available online dating back to 1992.

Little Cypress Bayou (0501B) has a presumed use of primary contact recreation based on the Texas Surface Water Quality Standards (TSWQS) (TCEQ, 2010). Prior to June 2010 only two categories of recreation use, contact and noncontact, existed in Texas. In June 2010, the TCEQ adopted revisions to the TSWQS that expanded the designation of contact recreation into three categories (primary contact recreation, secondary contact recreation 1, and secondary contact recreation 2) based on varying degrees of interaction with the water, while maintaining a fourth category of noncontact recreation. These revisions were codified in the Texas Administrative Code (TAC), Title 30 Chapter 307 and became effective as a state rule on July 22, 2010 (TCEQ, 2010). As a result of these revisions to the TSWQS, all water bodies listed as impaired based on bacteria for contact recreation are scheduled to undergo a standards review to determine if primary contact recreation is appropriate or if a revision to the use category for recreation should be considered.

Use attainability analyses (UAAs) are studies to evaluate the designated or presumed uses of a water body. In order to identify and assign attainable uses and criteria to individual water bodies, UAAs evaluate physical, chemical, biological, and economic factors affecting use attainment of a water body (40 Code of Federal Regulations §131.10(g)). A recreational use attainability analysis (RUAA) is a specific type of UAA focused on determining the appropriate recreational use

Objectives

The objective of this report is to present the findings of a Comprehensive RUAA for Little Cypress Bayou following the TCEQ March 2014 Procedures for a Comprehensive RUAA and a Basic RUAA Survey (TCEQ, 2014). An RUAA consists of three parts: field surveys to document water body characteristics and signs of recreation, interviews with stakeholders regarding past and current use of the water body, and a historical review regarding recreational use of the water body. All components of this RUAA were performed by Texas Institute for Applied Environmental Research (TIAER), which is located on the campus of Tarleton State University in Stephenville, Texas. Field surveys and interviews for the RUAA were conducted under a Texas State Soil and Water Conservation Board (TSSWCB) approved Quality Assurance Project Plan (QAPP; TIAER, 2015).

Stakeholder and Agency Involvement

The TSSWCB and its collaborating entities maintain an inclusive public participation process. From the inception of this project, the project team sought to ensure that stakeholders were informed and involved. TIAER provided coordination for public participation for this project.

Input from the TCEQ regional staff, United States Geological Survey regional staff, Texas Parks and Wildlife Department (TPWD) regional staff, TSSWCB, Orange County Drainage District, Lower Sabine and Neches Soil and Water Conservation District, Sabine River Authority (SRA) and other local agencies was solicited as well as input from watershed stakeholders on the need for the RUAA (see Contact Information Form available on the project website noted below).

Meetings with state agencies, river authority representatives, local officials, and stakeholders were held to give an overview of water quality issues within the Little Cypress Bayou watershed and to obtain comments on proposed survey sites prior to field data collection. Meetings targeted local and state agencies as well as stakeholders in an effort to inform them of the assessment of water quality within Little Cypress Bayou and the need for an RUAA. TIAER representatives met with officials from Orange County, the City of Orange, and Lower Sabine – Neches Soil and Water Conservation District on March 10, 2015.

A public meeting focusing specifically on the RUAA was held at the Sabine River Authority headquarters located in Orange, Texas on April 14, 2015. At this meeting input was sought on the proposed sampling sites for the Little Cypress Bayou RUAA. Attendees provided information regarding activities that typically occur within the watershed and offered assistance in accessing the stream via privately owned property.

On August 13, 2015, a second public meeting was held at the Sabine River Authority headquarters to inform stakeholders of the findings from the first RUAA field survey that was conducted on July 1, 2015. The importance of interviews in providing feedback on past recreational use was emphasized by TIAER. Interview forms were made available at this meeting as well as through the project website. Several attendees agreed to complete interviews.

A final public meeting occurred March 29, 2016 at the Sabine River Authority headquarters in Orange, Texas to inform stakeholders of the findings of both field surveys. The next steps of the RUAA were discussed at this meeting and feedback from stakeholders was solicited. At the

3


meeting, stakeholders were informed that the draft RUAA report is open for public review and comment. The draft report is available via the project website. Additionally, TIAER provided hard copies if desired by individuals.

Watershed stakeholders were invited to attend public meetings through mailed invitations, public announcements (TCEQ and TSSWCB webpages), and individual phone calls. Information on past meetings for this RUAA, presentations, and other information, can be found on the project’s website: Little Cypress Bayou Project Webpage2

Recreational Use Attainability Analysis for Little Cypress Bayou Chapter 2 Study Area

Chapter 2 Study Area

Description of Little Cypress Bayou

Little Cypress Bayou is located in Orange County within the coastal area of the Sabine River Basin. The Little Cypress Bayou watershed is approximately 13,222 acres (21 square miles) and includes a portion of the City of Orange, Texas. The most downstream section of Little Cypress Bayou (AU 0501B_01) flows through the Blue Elbow Swamp that includes the Tony Houseman State Park and Wildlife Management Area (Figure 1.1). Housing subdivisions are prevalent from the Highway 87 bridge crossing up to the Little Cypress Drive crossing.

Little Cypress Bayou (0501B) is defined as a tidal stream by TCEQ (TCEQ, 2012). The category of tidal stream is given to a water body if tidal activity has been observed on that water body and if total dissolved solids measured from water samples is equal to or greater than 2,000 mg/L and salinity is equal to or greater than 2 parts per thousand (TCEQ, 2012).

Climatic Conditions

Annual precipitation for the Little Cypress Bayou watershed was based on data obtained from the National Oceanic and Atmospheric Administration’s website (NOAA, 2015) for Orange, Texas. Normal precipitation (1987-2014) for Orange, Texas averages 61.3 inches per month with peak rainfall typically occurring in the months of June and July (Figure 2.1).

Land Use and Land Cover

The Little Cypress Bayou watershed lies within portions of three ecoregions as defined in the publication Ecoregions of Texas (Griffith et al., 2007). The majority of the watershed is located within the Flatwoods ecoregion. The western edge of the watershed is located within the Northern Humid Gulf Coastal Prairies and the south eastern edge is located within the Floodplains and Low Terraces ecoregion. In general all three ecoregions share similar physiography in that they are characterized as having flat plains with low gradient streams.

The dominant land cover within the Little Cypress Bayou is woody wetlands at 41.3% and is present throughout the watershed (Table 2.1 and Figure 2.3). Woody wetlands are especially prevalent in the lower portion of the watershed and correspond to the location of the Tony Houseman Blue Elbow Swamp. The combined developed land use classes represent approximately 22.7% of the watershed area and are mostly located within or in close proximity to the City of Orange.

The land use/land cover for the watershed area was obtained from the National Land Cover Database (NLCD) maintained by the U.S. Geological Survey (USGS, 2006). The land use/land cover categories within the watershed are described as follows from the NLCD legend:

Open Water – Areas of open water, generally with less than 25% cover of vegetation or soil.

Developed, Open Space – Areas with a mixture of some constructed materials, but mostly vegetation in the form of lawn grasses. Impervious surfaces account for less than 20% of total cover. These areas most commonly include large-lot, single-family housing units, parks, golf courses, and vegetation planted in developed settings for recreation, erosion control, or aesthetic purposes.

Developed, Low Intensity – Areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 20% to 49% percent of total cover. These areas most commonly include single-family housing units.

7


Developed, Medium Intensity – Areas with a mixture of constructed materials and vegetation. Impervious surfaces account for 50% to 79% of the total cover. These areas most commonly include single-family housing units.

Developed High Intensity – Highly developed areas where people reside or work in high numbers. Examples include apartment complexes, row houses, and commercial/industrial. Impervious surfaces account for 80% to 100% of the total cover.

Deciduous Forest – Areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. More than 75% of the tree species shed foliage simultaneously in response to seasonal change.

Evergreen Forest – Areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. More than 75% of the tree species maintain their leaves all year. Canopy is never without green foliage.

Mixed Forest – Areas dominated by trees generally greater than 5 meters tall, and greater than 20% of total vegetation cover. Neither deciduous nor evergreen species are greater than 75% of total tree cover.

Shrub/Scrub – Areas dominated by shrubs; less than 5 meters tall with shrub canopy typically greater than 20% of total vegetation. This class includes true shrubs, young trees in an early successional stage, or trees stunted from environmental conditions.

Grassland/Herbaceous – Areas dominated by gramanoid or herbaceous vegetation, generally greater than 80% of total vegetation. These areas are not subject to intensive management such as tilling, but can be utilized for grazing.

Pasture/Hay – Areas of grasses, legumes, or grass-legume mixtures planted for livestock grazing or the production of seed or hay crops, typically on a perennial cycle. Pasture/hay vegetation accounts for greater than 20% of total vegetation.

Cultivated Crops – Areas used for the production of annual crops, such as corn, soybeans, vegetables, tobacco, and cotton, and also perennial woody crops such as orchards and vineyards. Crop vegetation accounts for greater than 20% of total vegetation. This class also includes all land being actively tilled.

Woody Wetlands – Areas where forest or shrubland vegetation accounts for greater than 20% of vegetative cover and the soil or substrate is periodically saturated with or covered with water.

Emergent Herbaceous Wetlands – Areas where perennial herbaceous vegetation accounts for greater than 80% of vegetative cover and the soil or substrate is periodically saturated with or covered with water.

Regulated Sources

Potential sources of fecal pollution, as measured by indicator bacteria Escherichia coli (E. coli), can be divided into two primary categories: regulated and unregulated. Pollution sources that are regulated have permits issued by TCEQ under the Texas Pollutant Discharge Elimination System (TPDES) and/or by the USEPA under the National Pollutant Discharge Elimination System (NPDES) and are generally point sources. Examples of regulated sources include domestic and industrial wastewater treatment facilities (WWTFs); stormwater from industries, construction, and municipal separate storm sewer systems (MS4s) of cities; and concentrated animal feeding operations (CAFOs). These various regulated sources are required to have either an individual permit that is specific for each facility or a general permit for operation.

Wastewater Discharge Facilities The County Squire WWTF (TPDES permit WQ0011589-001) and the Longford Place WWTF (TPDES permit WQ0011155-001) are the only wastewater facilities permitted to discharge into Little Cypress Bayou. Both WWTFs are operated by the North Orange Water and Sewer, LLC. The County Squire WWTF is authorized to discharge treated wastewater at a rate not to exceed 0.153 million gallons per day (MGD). The Longford Place WWTF is permitted to discharge at a rate not to exceed 0.0315 MGD. Permits for both facilities contain limits for E. coli in which the monthly geometric mean shall not exceed 126 most probable number (MPN) per 100 mL and a single grab sample shall not exceed 394 MPN/100 mL for the County Squire WWTF and 399 MPN/100 mL for the Longford Place WWTF. The County Squire WWTF is required to monitor E. coli concentrations monthly, while the Longford Place WWTF is required to monitor E. coli quarterly. Data obtained from discharge monitoring reports for the past five years indicates that the average monthly flow for the County Squire WWTF has been approximately 0.03 MGD and the Longford Place WWTF has been approximately 0.02 MGD (USEPA, 2015). Discharge monitoring reports also reveal that over the past five years effluent discharged from both facilities have had instances in which E. coli concentrations have exceeded permitted limits. The County Squire WWTF had five instances in which E. coli concentrations exceeded the geometric mean limit and one instance in which the single grab sample limit was exceeded (Figure 2.4). The Longford Place WWTF had five instances in which E. coli concentrations exceeded both the single grab sample limit and the geometric mean limit (Figure 2.5).

Regulated Stormwater The TPDES and the NPDES Municipal Separate Storm Sewer (MS4) Phase I and II rules require municipalities and certain other entities in urban areas to obtain permits for their stormwater systems. Phase I permits are individual permits for large and medium sized communities with populations exceeding 100,000, whereas Phase II permits are for smaller communities that are located within an “Urbanized Area”. An “Urbanized Area” is defined by the U.S. Census Bureau as an area with populations greater than 50,000 and with an overall population density of at least 1,000 people per square mile. The City of Orange has a total population of 18,595 based

on 2010 population estimates from U.S. Census Bureau (USCB, 2010). The population of the City of Orange is less than what is required for Phase I and II permits; however the City of Orange is within an urbanized area identified as the Port Arthur Urbanized Area. The location of the City of Orange within an urbanized area, thus, necessitated that stormwater discharges be regulated under a Phase II general permit. A Phase II general permit (TPDES TXR040430) was issued to the City of Orange on October 27, 2010.

Concentrated Animal Feeding Operations

There are currently no permitted CAFOs located within the watershed of Little Cypress Bayou (0501B).

Potential Unregulated Sources

Unregulated sources are typically nonpoint source in nature, meaning the pollution originates from multiple diffuse locations and is usually carried to surface waters by rainfall runoff, and the sources are not regulated by permit under the TPDES and NPDES. Potential unregulated sources include wildlife (mammals and birds), large exotics, unmanaged feral animals (e.g., feral hogs), on-site sewage facilities (OSSFs), pets, and livestock.

Non-Permitted Agricultural Activities and Domesticated Animals

Activities such as livestock grazing close to water bodies and agricultural use of manure as fertilizer, can contribute E. coli to nearby water bodies. Livestock statistics were obtained from United States Department of Agriculture (USDA) National Agricultural Statistics Service website (USDA, 2012). While these are county level statistics and thus only a very rough estimate of livestock in the watershed (Table 2.2), these statistics indicate that beef cattle, goats, and horses are the most common livestock found within the watershed.

Domestic pets are another unregulated source of E. coli bacteria, particularly dogs, because storm runoff often carries these wastes into streams (USEPA, 2009). A rough estimate of the dog and cat population can be computed assuming there are 0.584 dogs and 0.638 cats per household (AVMA, 2012). According to the 2010 census there are 2,032 households within the Little Cypress Bayou watershed which indicates that there are potentially 1,187 dogs and 1,296 cats residing within the watershed.

Wildlife

E. coli bacteria are common inhabitants of the intestines of all warm blooded animals, including wildlife such as mammals and birds. Wildlife are naturally attracted to riparian corridors of streams and rivers. With direct access to the stream channel, the deposition of wildlife waste can be a concentrated source of bacteria loading to a water body. Fecal bacteria from wildlife are also deposited onto land surfaces, where it may be washed into nearby streams by rainfall runoff.

Failing On-Site Sewage Facilities

Septic systems or on-site sewage facilities (OSSFs) are often used in rural areas that do not have the ability to connect to a central wastewater collection system. To estimate the number of potential OSSFs in the watershed, a GIS layer associated with the sewer Certificates of Convenience and Necessity (CCNs) from the Public Utility Commission of Texas was used. Because not all cities with WWTFs have CCNs, the CCN layer was supplemented with a GIS layer representing municipal boundaries. Population data from the U.S. Census Bureau were then overlaid masking out areas that would likely be serviced by WWTFs. Of the 2,032 households in the Little Cypress Bayou watershed, approximately 35% were outside of areas serviced by WWTFs and thus likely on septic systems.

Historical Information on Recreational Use

A review of historical information was performed regarding recreational water uses for Little Cypress Bayou. The review considered the time period of November 28, 1975 to the present in accordance with 40 CFR Part 131 (EPA standards regulation). Government offices, libraries, and newspapers were searched and contacted in addition to generic internet searches. The following is a summary of the review and searches.

Recreational Use Attainability Analysis Chapter 3 Little Cypress Bayou in Orange County

Chapter 3 Little Cypress Bayou in Orange County (501B)

Survey Site Descriptions

Little Cypress Bayou (0501B) is 8.5 river miles long indicating a goal of five sites (3 sites per 5 miles of river) for the RUAA survey. With the help of cooperating stakeholders, TIAER was able to establish a total of six survey sites along Little Cypress Bayou (Figure 3.1 and Table 3.1). Five of the six sites were located at public road crossings and one site was accessible via boat from the Sabine River or from an upstream bridge crossing.

The boat accessible site, Site LC01, is located within the Blue Elbow Swamp – Tony Houseman Wildlife Management Area/State Park. This WMA is a cooperative effort between the Texas Department of Transportation and Texas Parks and Wildlife. According to website information, the easiest way to access the area is by boat from one of two boat ramps in the area. One public boat ramp is located at Bluebird Fishing Camp, just south of Interstate Highway 10 on State Highway 90 in Orange, Texas. The second boat ramp is located at the end of Pine Bluff Road within the WMA. According to a Texas Parks and Wildlife representative, the boat ramp belongs to TPWD but is utilized and maintained by local residents. Outdoor recreation opportunities within the WMA include public hunting, fishing, wildlife viewing, hiking, and canoeing.

At the five publicly accessible sites, there was actually very limited public access due to private property fences upstream and downstream of the crossings. Access to the stream between road crossings was moderately difficult due to steep banks and dense vegetation, in addition to the areas being private property. Three of the publicly accessible sites were co-located with TCEQ sampling stations. RUAA surveys were performed July 1, 2015 and August 13-14, 2015 at all locations. A brief description of each site follows.

Site LC03 allowed limited public access at the bridge crossing with private property upstream and downstream of the crossing. The site was selected because of public access and the site provided opportunity for characterization of 0501B.

Site LC04 (TCEQ Station 15520) is located on Little Cypress Bayou at the bridge crossing on Bear Path Drive, north of Orange, Texas. Site LC04 was only publicly accessible at the bridge with private property upstream and downstream of the crossing. The site was selected because of public accessibility and the site provided opportunity for characterization of 0501B.

Site LC05 (TCEQ Station 16690) is located on Little Cypress Bayou at the bridge crossing on Little Cypress Drive, north of Orange, Texas. Site LC05 was only publicly accessible at the bridge with private property upstream and downstream of the crossing. The site was selected because of public accessibility and the site provided opportunity for characterization of 0501B.

Site LC06 is located on Little Cypress Bayou at the culvert crossing on Teal Street, north of Orange, Texas. Site LC06 was only publicly accessible at the culvert with fenced private property upstream and downstream of the crossing. The site was selected because of landowner cooperation and the site provided opportunity for characterization of 0501B.

Field Survey Results and Discussions

General Description of RUAA Survey Sites and Conditions for Little Cypress Bayou 0501B

The Little Cypress Bayou RUAA surveys were conducted on July 1, 2015 and August 13-14, 2015 at all six sites. The surveys were performed on weekdays, weekends, or holidays at opportune times to observe recreational activities. Air temperatures prior to and during both the first and second surveys were above 21°C (70°F) indicated by the RUAA guidelines as warm enough to promote recreational activities (Tables 3.2 and 3.3). In the 30 days prior to the first survey, 5.62 inches of precipitation fell, while 0.33 inches fell 30 days prior to the second survey. On the day of the first survey (July 1, 2015) 0.33 inches of precipitation was recorded (Table 3.2); however, the precipitation occurred during the evening hours after the first survey had been completed. On August 13, 2015 0.08 inches of precipitation was recorded prior to initiation of the second survey. The precipitation amount and intensity was not significant enough to hinder stream access or

18


increase stream flow. The Palmer Drought Severity Index (PDSI) represented moderately wet conditions for East Texas during both July and August 2015 (TWDB, 2015).

A summary of the RUAA field survey results is presented in the following tables:

Table 3.5 describes the stream channel and corridor characteristics at each site.

Table 3.6 notes the average thalweg depth by site during each survey and the access to the stream, whether public or private, and the ease of bank access.

Tables 3.7 and 3.8 document the maximum, minimum, and average stream widths at each site for each survey and observed flow conditions.

Tables 3.9 and 3.10 note stream aesthetics, wildlife observations and tracks, and the presence of garbage by site observed during each survey.

Physical descriptions of each site follow these tables along with selected photos showing notable characteristics of each site. Overall thalweg depth averaged 1.4 m for the first survey and 1.3 m for the second survey. Access to the stream was difficult or moderately difficult at five of the six sites due to steep, densely vegetated banks. Access at Site LC06 was easy due to the gentle banks with a mowed and maintained corridor. The dominant substrate was mud/clay, and the stream corridor was largely lined with trees except in a few locations where mowed pastures abutted the stream. The maximum stream width encountered was 27 m at the bridge crossing at Site LC02. Typical stream widths were wider at the most downstream Site LC01, and gradually narrowed while traveling upstream. Flow conditions were largely high at the lower sites and normal at the upper sites during both surveys. The most upstream site (LC06) had no flow during the first survey and was dry during the second survey. The water had a surface scum at all sites except Site LC06, which was clear during the first survey and void of water during the second survey. The water observed at Sites LC01 through LC05 was brown in color. No tracks were observed during either survey due to the dense vegetation and TIAER personnel utilizing a boat to conduct the surveys. However, even at the bridge crossing where vegetation was absent, no tracks were observed. Trash was rarely observed at most survey sites and when observed was predominantly typical plastics, aluminum cans, and bottles. Fishing tackle was observed at Site LC02 underneath the bridge crossing. No other evidence of recreation was observed at the other five survey sites. Evidence of potential recreation was observed while traveling via boat from site to site. Chairs, fishing tackle, fishing platforms, and a small boat were observed along the banks at a few locations between sites.

Physical Description of LC01

Little Cypress Bayou at Site LC01 was visited on July 1 and August 14, 2015. This site was located approximately 1.5 miles downstream of the bridge crossing on Farm-to-Market (FM) Road 3247, Northeast of Orange, Texas in Orange County. The site can only be publicly accessed via boat upstream from the Sabine River or immediately downstream from the bridge crossing at FM Road 3247. TIAER personnel accessed the site by launching a boat from a private boat ramp near FM Road 3247 and traveled downstream. Site LC01 is located within the Blue Elbow Swamp – Tony Houseman Wildlife Management Area / State Park.

The site is located in a forest dominated corridor (Table 3.4). At the site, access to the stream was difficult due to the swamplike conditions of the banks and dense vegetation. Navigating the stream in a boat is the easiest way to reach this portion of the Bayou. Figures 3.2 and 3.3 depict the appearance of the site during each of the surveys.

Figure 3.2 Photograph of Little Cypress Bayou Site LC01 taken on July 1, 2015. The right bank

of the 300-m transect.

Site LC01 was not wadeable as average thalweg depths were greater than 2.0 m during both surveys. The relatively deep water necessitated the use of a small boat to conduct both surveys. Stream widths were collected using a range finder and ranged from a minimum of 15 m to a maximum of 26 m with a typical width of 25 m during both surveys (Tables 3.6 and 3.7).

TIAER staff in photograph.

There was a slight presence of water dependent birds observed during the first survey with no other vertebrates observed during either survey (Tables 3.8 and 3.9). No wildlife tracks or feces were observed during either survey due to an inability to see most of the stream bank. Aquatic vegetation was rare during both surveys, and algae cover was absent. Trash observed was rare to non-existent and when encountered, consisted of plastic bottles. No evidence of human presence was observed throughout the reach during either survey.


Little Cypress Bayou at site LC02 was visited on July 1 and August 14, 2015. This site was located northeast of Orange, Texas in Orange County. Site LC02 was only publicly accessible at the bridge crossing on FM Road 3247 with fenced private property located upstream and downstream of the crossing. With landowner permission, TIAER personnel launched a small boat from a private boat ramp immediately downstream of the bridge to conduct the survey of the 300-m reach.

The majority of the stream corridor was forested along both banks except for approximately 150 m along the right bank, which was mowed and maintained by a landowner (Table 3.4). At the site, access to the stream was moderately difficult throughout most of the reach due to densely vegetated forest areas along both banks (Table 3.5). There were two locations within the survey reach that provided easier stream access. One location was the private boat ramp utilized by

28


TIAER field personnel to conduct the survey. The second location was the bridge crossing of FM Road 3247, which had two mowed bar ditches. Figures 3.4 and 3.5 depict the site during each of the surveys.

Figure 3.5 Photograph of Little Cypress Bayou Site LC02 taken on August 14, 2015.

The upstream view of the 150-m transect.

Site LC02 was non-wadeable for the entire 300-m reach length. Average thalweg was 1.7 m during both surveys (Table 3.5). Due to the stream depths, TIAER personnel utilized a boat to traverse the survey reach and collected depths and widths at each transect. Stream widths ranged from a minimum of 16 m to a maximum of 27 m with a typical width of 18 m (Tables 3.6 and 3.7). There were no obstructions encountered within the reach during either survey. A railroad crossing was located near the 0-m transect.

During the first survey, there was a slight presence of snakes, alligators, and domesticated pets (the landowner’s dog) observed within the reach. There were no mammals or other vertebrates observed during the second survey (Tables 3.8 and 3.9). Due to the densely vegetated banks, no tracks or feces were observed during either survey. Aquatic vegetation was rare and algae was absent during both surveys. Water color was brown with a surface scum identified during each survey. Trash consisting of typical plastic bottles and cups was rarely observed within the stream channel. No trash was observed on the bank. Fishing tackle was observed underneath the bridge crossing with no evidence of recreation observed throughout the rest of the reach.


Little Cypress Bayou at Site LC03 was visited on July 1 and August 14, 2015. This site was located north of Orange, Texas in Orange County at the bridge crossing on State Highway 87. TIAER personnel accessed the site by traveling upstream in a boat from a private boat ramp located at Site LC02. The stream corridor was forested during the first survey and was shredded

30


during the second survey (Table 3.4). Access to the stream throughout the reach was moderately difficult due to dense vegetation and steep banks as shown in Figure 3.6. The shredded bank observed during the second survey is shown in Figure 3.7.

Site LC03 was non-wadeable for the entire 300 m reach length. Average thalweg was 1.6 m during the first survey and 1.5 m during the second survey (Table 3.5). Widths of the stream during both surveys ranged from a minimum of 9.0 m to a maximum of 18 m. The typical stream width was 13 m during the first survey and 12 m during the second survey (Tables 3.6 and 3.7). There were no channel obstructions encountered within the 300-m survey reach, but there was one tree obstruction located between Sites LC02 and LC03, which TIAER personnel were barely able to travel underneath.

There were no mammals, reptiles, or water dependent birds observed during either survey (Tables 3.8 and 3.9). Due to dense vegetation along both banks and TIAER personnel utilizing a boat to survey the reach, no tracks or feces were observed during either survey. The presence of aquatic vegetation was rare and algae cover was absent during both surveys. The water color during both surveys was brown with a surface scum and no odor. Small trash was observed within the stream channel consisting of typical plastics with no bank garbage observed during either survey. No evidence of human recreation activity was observed within the survey reach.

Little Cypress Bayou at Site LC04 was visited on July 1 and August 14, 2015. This site was located north of Orange, Texas in Orange County, and was only publicly accessible at the bridge crossing on Bear Path Drive with fenced private property upstream and downstream of the bridge. The stream corridor was forest and shrub dominated on both banks during the first survey (Table 3.4). During the second survey, the left bank had been deforested and the mulched debris left along the bank. A fenced city utility station was located at the bridge crossing on the right bank. Access to the stream throughout the reach was moderately difficult due to steep slopes and dense vegetation (Table 3.5). The general appearance of the creek at this location is shown in Figures 3.8 and 3.9.

Site LC04 was non-wadeable for the entire 300-m reach length with an average thalweg of 1.3 m during the first survey and 1.1 m during the second survey (Table 3.5). TIAER utilized a small boat to survey the stream and no obstructions were encountered within the survey reach. Widths of the stream were similar during both surveys and ranged from 12 m to 7.5 m with a typical width of 10 m (Tables 3.6 and 3.7).

There were no mammals or other vertebrates observed during either survey (Tables 3.8 and 3.9). No tracks or feces were observed during either trip due to the densely vegetated banks. Aquatic vegetation was rare and algae was absent during both surveys. The brown colored water had a surface scum during each survey. Trash was rarely observed within the stream channel and consisted of typical plastics and no trash was observed along the banks. Evidence of potential recreation was not observed within the survey reach.


Little Cypress Bayou at Site LC05 was visited on July 1 and August 14, 2015. This site was located north of Orange, Texas in Orange County. It was publicly accessible at the bridge crossing on Little Cypress Drive with fenced private property upstream and downstream of the crossing. The stream corridor consisted primarily of forest and shrubs with some areas of mowed pasture land on alternating banks throughout the reach. (Table 3.4). During the second survey the right bank had been deforested. Access to the stream was moderately difficult due to the steep banks and dense vegetation (Table 3.5). The general appearance of the site during each survey is shown in Figures 3.10 and 3.11.

Site LC05 was non-wadeable for the entire 300-m reach length with average thalweg depths of 1.2 m during the first survey and 1.1 m during the second survey (Table 3.5). The dominate substrate of the stream at this site was mud/clay. Widths ranged from a maximum of 10 m during the first survey to a minimum of 6.0 m during the second survey with a typical average width of approximately 7.5 m across both surveys (Tables 3.6 and 3.7). One tree obstruction was observed just above the 300-m transect. Other submerged and overhanging obstructions were encountered, but TIAER personnel were able to navigate around them.

There were no mammals or other vertebrates observed during either survey (Tables 3.8 and 3.9). Due to the dense vegetation and TIAER personnel traveling in a boat, no tracks or feces were observed during either survey, not even at the bridge crossing where bare ground was observed. Aquatic vegetation was rare, algae cover was absent, and the water color was brown with a surface scum observed during both surveys. Trash was rarely observed within the channel and when encountered, consisted of typical plastic cups and bottles. No other trash, large or small, was observed along the banks throughout the survey reach. Evidence of potential human recreation was not identified within the survey reach.

Little Cypress Bayou at Site LC06 was visited on July 1 and August 13, 2015. This site was located north of Orange, Texas in Orange County, and was only publicly accessible at the culvert crossing on South Teal Street with fenced private property upstream and downstream of the crossing. TIAER personnel entered the stream at the culvert and conducted the survey downstream from the road crossing. The stream corridor was primarily forest on both banks except for a mowed corridor along a pipeline (Table 3.4). At the site, access to the stream was easy via the left bank (Table 3.5), but access via the right bank was more challenging due to dense forest. Figures 3.12 and 3.13 depict the general appearance of the site during each of the surveys.

Site LC06 was wadeable for the entire 300-m reach length. Average thalweg during the first survey was 0.2 m when water was present. No water was encountered during the second survey (Table 3.5). During both surveys, the mud/clay substrate and open channel made traversing the stream channel very easy. Widths of the stream ranged from 3.5 m to 2.0 m with a typical average width of 2.5 m during the first survey (Tables 3.8 and 3.9). There were no obstructions encountered during either survey.

One deer was encountered during the second survey but no other animals, tracks, or feces were observed during either survey (Tables 3.8 and 3.9). Aquatic vegetation was common and algae was absent during both surveys. The water color, when present, was clear with no surface scum or foam observed. Trash was only observed during the second survey and consisted of typical plastics and bottles located primarily at the road crossing. No evidence of recreational activity was found within the reach.

Observations and Interviews

Activities Observed

During each RUAA survey, field personnel visited sites during times of day and on days when recreational activities were most likely to be observed. Five of the six sites were at public road crossings; however, private property boundaries generally limited public access to small areas around and underneath bridge crossings. The most downstream site (LC01) was located within a WMA and was only publicly accessible by boat.

No form of recreation was directly observed by TIAER staff during either of the two surveys. Utilizing a small boat to conduct both surveys, TIAER personnel were able to not only observe conditions along the reaches of established sites but also the areas between sites from LC01 up to LC05. Evidence of potential recreation was encountered at Site LC02, between Sites LC02 and LC03, and between Sites LC03 and LC04.

At Site LC02 fishing tackle was observed underneath the bridge crossing on FM Road 3247. The bar ditch alongside the road was mowed and maintained allowing for easy access to the bank of the stream.

Between Sites LC02 and LC03 two plastic chairs and fishing tackle were observed along the bank of the stream. The bank was mowed and appeared to be maintained as a private fishing spot. A rope tied to a tree was observed and may have been used to lower a minnow trap into the stream; however, the exact purpose was unknown. A couple of juglines were also observed beside the chairs. Figure 3.14 shows the chairs, juglines, fishing tackle, and a rope tied to the tree.

As previously stated, during the second survey between Sites LC03 and LC04, the left bank had been shredded and the mulch left along the banks. One resident took advantage and built a new pier and fishing platform as shown in Figures 3.15 and 3.16. The pier and fishing platform were not observed during the first survey and appeared to have been recently constructed. At another location between these two sites, TIAER personnel observed some chairs and a boat on the bank at the back of a landowner’s house (Figure 3.17). Due to the lack of vegetation, it appeared possible to lower the boat down the bank into the stream.

Activities Interviewed

A total of 11 interviews were collected from landowners along Little Cypress Bayou as well as others with interest in the watershed. The interviews indicated fishing and boating as the most common recreational activities occurring throughout the creek, while swimming and wading were noted at only one location from one interview (Table 3.10).

Swimming and wading were noted at Site LC02. An interview collected from a landowner at Site LC02 stated that he had personally swam in the stream as a youngster, but that was well before 1975. He currently uses the stream for boating and fishing and has constructed a private boat ramp on his property, which TIAER utilized to access the stream. He further stated that he had observed people fishing at LC02 throughout the year on a weekly basis. He periodically had observed young adults (high school age), swimming, wading, boating, and fishing in the area around the bridge crossing and also downstream of the bridge at the railroad bridge crossing. He had on occasion discouraged these young people from recreating in the water, but they typically ignored his warnings about alligators and other submerged hazards.

Interviews collected from landowners at sites LC01 and LC04 stated that the stream was primarily used by locals for fishing and boating. Some hunting was also noted but not as frequent. Many of the interviews stated that most of the recreation occurred from LC04 downstream to the confluence with the Sabine River. Two interviewees stated to have not personally used, seen others use, or heard of others using the stream for any form of recreation.

Summary

RUAA surveys were conducted at six sites along Little Cypress Bayou (0501B) on July 1, 2015 and August 13-14, 2015. Temperatures were above 21ºC (70ºF) during the 30 days prior to each survey (Tables 3.2 and 3.3). Stream flow was considered normal to slightly high during both surveys based on information provided by local residents. The Palmer Drought Severity Index (PDSI) indicated moderately wet conditions during both July and August 2015 (TWDB, 2015).

No recreational activities were observed by TIAER field staff during either survey. One private boat ramp was observed at Site LC02. No characteristics, such as boat docks, parks, playgrounds, biking trails, campgrounds, or sports fields, were encountered at any of the survey sites; however, because TIAER personnel boated the entire length of the water body from Site LC01 to Site LC05, staff did observe fishing platforms, chairs, fishing tackle, and a boat at locations between the survey sites. These observances would indicate that local residents do utilize the stream for recreation, mainly fishing and boating.

Interviews indicated fishing and boating as the most common recreational activities occurring within the stream, primarily from Site LC04 to the confluence with the Sabine River. Swimming and wading were noted at one site (LC02) from one landowner interview. Public access to the stream is limited primarily to the right-of-ways immediately surrounding bridge crossings or areas immediately up and down stream of culvert crossings, typically ranging from 3 to 10 meters. Public access to Site LC01 (located within the WMA) was only available by boat.

Recreational activities observed and reported in interviews are summarized in Figure 3.18. Overall RUAA findings are summarized in the form below.
