An Environmental Flows Information System for Texas
Eric S. HershThe University of Texas at Austin
Center for Research in Water Resources
December 14, 2009TCEQ
Outline• EFIS background, concept, and contents• EFIS site: design and use– Interactive Map Viewer
– Digital Repository
– HydroPortal
– Calculator for Low Flows
• What’s Next– HydroDesktop
“The State should be encouraged to mount a comprehensive review and digitization project to recover all of this data and make it available to stream ecologists and other scientists.”
-Science Advisory Committee (2004)
“With detailed ecological/environmental flow information for just one reach of one river, the ability of the TRG to fulfill its fundamental goal of evaluating the appropriateness of various desk-top methods, including the Lyons Method, for estimating environmental flow requirements for stream and ecological conditions across the State has, at the least, been substantially impaired.”
-Technical Review Group (Draft, 2008)
“All available data and study reports related to the hydrologic, biologic, geomorphic, water quality, and connectivity of the study area will be assembled.”
-Texas Instream Flow Studies: Technical Overview (2008)
Motivation
Trinity/San Jacinto/Galveston BBESTNWF Meeting Summary, 2/27/09
Available Information and Knowledge Gaps
“The BBEST acknowledged that the only complete data set for instream flows at their disposal is hydrological and therefore the geographic scope of their recommendations will be critical.”
Background• Primary Goal:
– data and integration to help TCEQ in establishing environmental flow requirements in Texas
• Added Benefit:
– Support for SB2/SB3
– Stakeholders, BBESTs, tri-agencies
• Other efforts:
– Bio data collection, basin lit reviews, SAC, HEFR/MBFIT

EFIS Concepta diversity of disciplines and data types means no one solution
• A blend of old & new technologies– A person interacting with a website and downloading a file– A PC interacting with a server, retrieving and analyzing data
EFIS Concept (2)• A blend of GIS & HIS– Geographic Information Systems with geographic data models– Hydrologic Information Systems with relational data models– A “system of systems”
Water Environment
- Geospatial data layers
Water- Observations

EFIS Contents
• Four disciplines:– Hydrology– Water Quality– Biology– Geomorphology &
Physical Processes
Plus,– Tools & Guidance
Point of departure:
TCEQ‘Wish List’
EFIS Organization
• Six information types:– Point observations data (eg: WaterML/ODM )
– Geographic (shapefile, feature class, KML, WFS/etc)
– Documents (DSpace digital archive)
– Tables (conservation status, guilds)
– Tools (CALF, TSA, HydroExcel)
– Links (Fishes of Texas, IHA, SAC)
EFIS Use
• Four access types:– Web Page– Interactive Map Viewer– Digital Library– HydroPortal
EFIS Contributors (n = 25+)
• State: TCEQ, TWDB, TPWD, TCOON, TIFP, TNRIS, TXDOT
• Federal: USGS, EPA, NWS, USACOE HEC, NOAA, USFWS, NAS NRC

-Sabine River: 165 samples were collected at 8 study reaches over 8 days of field work in 2006; 147 samples yielded fish-5,811 fish were observed, representing 58 species-each sample yielded an average of 40 fish
Across all sites, 889 Centrarchids (sunfish, bass, and crappies) were observed with a relative abundance of 22% ± 24% (mean ± SD)
-Three blue suckers (Cycleptus elongatus) observed; a state-listed threatened species
-The only fish non-native to the Sabine River Basin observed was the inland silverside (Menidia beryllina).-192 silversides total, ranging from 0-90% of the sample population with a mean of 3% ± 12%
Distribution: Originally found in coastal waters and upstream in coastal streams along the Atlantic and Gulf coasts; widely introduced into freshwater impoundments (Hubbs et al. 1991)
