COMPREHENSIVE DATABASE FOR SPRINGS IN TEXAS
Prepared by:Ben Bates, Jason Pickett, Mark Pillion, Yasmin Sierra
Final Report
BACKGROUND
Springs are naturally occurring features creating a valuable freshwater resource for Texas. Springs, in Texas, have tremendous economic, cultural, ecological, aesthetic, and recreational value.
BACKGROUND
Springs are Texas’ primary freshwater resource. Aquifers store and transmit the groundwater
www.bing.com
BACKGROUND
The amount of water that issues from a spring depends on many variables including Aquifer water pressure The rock sizes in the cavern Spring basin characteristics Precipitation trends Anthropogenic causes
BACKGROUND
Spring flow can vary greatly Relatively constant flow Flow that fluctuates greatly according
to Season Precipitation trends
MAJOR & MINOR AQUIFERS
9
21 MINOR AQUIFERS
9 MAJOR AQUIFERS
ANTHROPOGENIC USES INCLUDE:
Extraction Consumption
Irrigation Agriculture Sanitation Industry Energy
PROBLEM
Springs in Texas are documented by various agencies and organizations throughout Texas
A particular spring’s exact location and attribute data may vary according to its source Much of the data is duplicate data Inconsistencies exist within the data
PROBLEM
Format of available data Spring data exists in a shapefile format or
can be found through complicated queries from the source websites
The average person does not have access to GIS software and does not have GIS training; therefore, the data is currently un available for a large part of the community
OBJECTIVE
To create a comprehensive database that will be in 2 formats
Shapefile format For those that have access to ArcGIS
User friendly format - compatible with Google Earth For those without ArcGIS access
EXTENT OF PROJECT
DUPLICATE DATA
INCONSISTENCIES
IMPLICATIONSIt is the goal of this project to create a resource that will generate interest from the community and researchers
Through education and awareness, we hope to generate a public interest to preserve one of Texas most remarkable features
This comprehensive database will potentially serve as a platform for additional data collection, documentation, and analysis for the springs in Texas
This database can be used to add new or additional springs data in order to build a more resourceful database
TOOLS
ArcGIS is a software that provides a standards-based platform for spatial analysis, data management, and mapping
ArcGIS was used by THI for efficient data management Using ArcMap, THI was able to efficiently
integrate the data from multiple tables into one central table

Future research Discharge Aquifer analysis Development of aquifer recharge and use models in GIS
CONCLUSION Accomplished all goals.
The data is now very organized and characteristics of any particular spring can be found and accessed with ease.
Dataset will provide much easier access to all GIS and non GIS viewers. Interactive map allows every day people to view the beauty of the
springs with Google Earth as well as the information about each spring. The goals with the project have been met and we believe
that we were very successful in making the data very easy to find and understand.
The GIS analytical process is very suitable for our research. Our training in GIS helped provide the tools for us to
accomplish these very goals. This research help us build new skills as well as team skills
which will better prepare us for the real work place.
