Navigable Waters of the U.S.

Navigable Waters of the United States are those waters that are subject to the ebb and flow of the tide and/or

are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign

commerce (33 CFR Part 329).

Navigable Waters

Navigable waters of the United States are those waters that are subject to the ebb and flow of the tide and/or are presently used, or have been used in the past, or may be susceptible for use to transport interstate or foreign commerce. A determination of navigability, once made, applies laterally over the entire surface of the waterbody, and is not extinguished by later actions or events which impede or destroy navigable capacity.

CFR 328.3(a) a. The term "waters of the United States" means 1. All waters which are currently used, or were used in the past, or may be

susceptible to use in interstate or foreign commerce, including all waters which are subject to the ebb and flow of the tide;

2. All interstate waters including interstate wetlands; 3. All other waters such as intrastate lakes, rivers, streams (including

intermittent streams), mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds, the use, degradation or destruction of which could affect interstate or foreign commerce including any such waters:

i. Which are or could be used by interstate or foreign travelers for recreational or other purposes; or

ii. From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or

iii. Which are used or could be used for industrial purpose by industries in interstate commerce

In 1984 a portion of the Corps’ regulatory responsibilities was assumed by the Michigan Department of Environmental Quality (MDEQ) Unless otherwise notified, a separate

authorization from the Corps is not required

When to get a Corps JD

You should request a Jurisdiction Determination any time a proposed project is in one of the Great Lakes, a tributary to a Great Lake, or in adjacent wetlands

When in doubt – give us a call

The Corps Ordinary High Water Mark

The U.S. Army Corps of Engineers Ordinary High Water Mark (OHWM) is a jurisdictional benchmark for administering its regulatory program in navigable waterways under Section 10 of the Rivers and Harbors Act and Section 404 of the Clean Water Act. The OHWM is the line on the shore coincident with the elevation contour that represents the approximate location of the line on the shore established by fluctuations of water and indicated by physical characteristics such as shelving, destruction of terrestrial vegetation, presence of litter or debris, or changes in the character of soil. The OHWM varies from lake to lake and within each of the connecting channels (e.g., St. Marys River, St. Clair River). A table of OHWMs for several locations throughout the Great Lakes region can be found below. The elevation reference system used to define Great Lakes water levels is the 1985 International Great Lakes Datum, which is commonly known by the acronym IGLD 1985.

All streams and drains have a floodplain

Non-mapped floodplains may be regulated!

DEQ Part 31 We do not have a publically available map of all

regulated floodplain areas. Please call your local floodplain engineer to

determine if the drainage area for your project is > or < 2 sq. miles.

DEQ Wetlands Regulated

wetlands do not stop at property lines.

Paired sampling points are required to show that wetlands are not connected.

Paired sampling points Orange dots =

wetland characteristics

Purple area = upland characteristics

Both sets of data need to be turned in with an application or delineation.

Inland Lake and Stream jurisdiction example

Many statues overlap. Depending on where your project area is, three or more statutes may apply.

DEQ Part 315 Dam height is > than

6ft or impoundment area is greater than 5 acres

Many regulated activities will involve more than one state law and gov’t agency

Michigan’s Wetland Identification Program (WIP)

The DEQ offers wetland delineations to determine the regulated wetlands on the property.

Keto Gyekis, 517-243-5002, [email protected]

Benefits:► Jurisdictional determination► Wetlands are clearly identified for an application► Due diligence for propertybuy/sell agreements

mailto:[email protected]

WIP fee structure Level 1: DEQ Wetland inventory maps Level 2: On-site review of an identified area, up to five

acres, by DEQ staff► $500 for 1st acre, $250 per additional acre

Level 3: On-site verification of a delineation done by a wetland professional and/or consultant► $500 for 1st acre, $50 per additional wetland acre, $20 per additional upland acre

Wetland Verification Delineation may be required for

application completeness Considering wetlands during development

of plan helps with avoidance/minimization You may be able to avoid wetland impacts

(possibly avoiding need for permit – we can help you identify areas to avoid) Correctly quantify impacts – minimize

delays later in evaluation

Important Distinctions

The Corps and DEQ are separate regulatory authorities and cannot speak for each other’s programs, verify wetland boundaries, or determine jurisdiction. ONLY the Corps can make a jurisdictional

determination for the Corps of Engineers. A consultant can provide a wetland

delineation but cannot make a final jurisdiction determination.

Data Sheets: Common Issues Correct Data Sheets Missing Information – don’t leave blanks Data point location

► Give accurate coordinates► Provide a map

Inadequate review – if you used the fillable form double check and review Use the comments section – you should

always share your observations

Focus on probable boundaries Which tells you more about the wetland

boundary location?

Use Correct Datasheet Midwest or Northcentral/Northeast

►Most recent: Version 2.0►Hydric soil and wetland hydrology indicators

may vary►Plant indicator status may vary

• Refer to USACE National Wetland Plant List for current taxonomy and indicator status

►Datasheets that predate the regional supplements may not reflect current methodology.

Hydrology indicators Make sure these

two sections are consistent.

If a water table is present, then saturation is also present, usually a few inches above the water table.

If surface water is present, a water table is usually present (0 inches depth).

Hydric Soil Indicators

How do these sections relate?• Refer to the regional supplement

for step-by-step definitions.• Go through each indicator that may

apply for the relevant soil texture (all soils, sandy, or loamy/clayey).

• More than one indicator may apply.

Atypical Situations: Disturbed Sites

Atypical Situations:Disturbed Areas

Industrial past Covered with fill Excavated Altered by mowing, plowing, planting,

drainage, flooding, etc.

Delineation of Disturbed Areas

Delineate early in the season Use procedures in the manual – and seek

additional resources Describe the problem in the “remarks”

section of the data sheets Provide all documentation used to inform

your decisions
