This Executive Summary to the 2003 Basin Summary Report, Sabine River Basin, Texas, was prepared in cooperation with the Texas Commission on Environmental Quality (TCEQ) under the authorization of the Texas Clean Rivers Act.

Activities and Accomplishments

Since initial operational activities began in 1954, the Sabine River Authority of Texas (SRA) has taken an active role in water quality matters and over the years has expanded its services to meet increasing needs throughout the Sabine River Basin.  The SRA was established with responsibilities to control, store, preserve, and distribute the waters of the Sabine River and its tributary streams for useful purposes. 

The water quality laboratory services and field programs are conducted by the Environmental Services Division (ESD) which operates a modern, well-equipped water quality testing laboratory near Orange.  The SRA provides these services because they fulfill demonstrated needs and have proven to be beneficial for the SRA and its customers in managing and protecting the water resources in the Sabine Basin.

As part of its commitment to serve the evolving water resource needs of the Sabine Basin, SRA reorganized the Water Resources Branch (WRB) creating a new division, Resource Management/ Project Development (RMPD).  The focus of the RMPD is to assist in water resource planning and development activities such as water supply, water resources protection, water quality issues, information management, and environmental services support.

The SRA uses a watershed approach to assess water quality conditions in the Sabine Basin.  This methodology includes all available information in the SRA Watershed Inventory.  In addition to water quality data collected by the SRA, datasets for the inventories have been received from a number of sources including municipalities, government agencies (local, state, and federal), and universities.  Water quality data was not available for some subwatersheds, but assessments were possible due to the information available in the subwatershed Inventories.  Data from September 1998 through August 2003 (5 years) were analyzed for this summary report.  Trend analyses were also conducted for representative sites using water quality data collected from September 1993 through August 2003 (10 years).  Spatial analyses were performed by subwatershed to correlate the water quality conditions with environmental factors. 


Significant Findings

Water quality assessment summaries were developed by analyzing water quality data and all other available information for each subwatershed.  The primary water quality issues are elevated bacteria levels and low dissolved oxygen.  The problems tend to be in small streams with low elevation gradients.  In most cases the problems occur infrequently and do not appear to significantly impact the designated use of the water body.  Some of the impacts are due to excessive loading from point sources, but many of the concerns are the result of non-point source pollution or natural conditions.  Assessments are presented below for each subwatershed in the Sabine Basin.

Recommendations

Many of the water quality issues are the result of natural conditions due to the low elevation gradients, soil types, and deciduous forests.  The assessment conducted by TCEQ has listed several Sabine Basin Segments and unclassified segments as impaired and all listings for the Sabine Basin have been categorized as being in need of additional information or data before scheduling a Total Maximum Daily Load Project (TMDL).  The SRA has provided information to TCEQ about each waterbody listed and in many cases has accounted for the existing water quality issues.  Most of the listed waterbodies would not benefit from a TMDL.  Many of the water quality issues are the result of applying segment standards to small tributaries that could not be reasonably expected to have similar water quality as classified segments.  Many of these small tributaries were studied by SRA to help categorize the overall water quality in the Sabine Basin.  The Texas Surface Water Quality Standards (TSWQS) specify that the average dissolved oxygen values in water designated for high aquatic life use should be 5 mg/L.  The TSWQS also specifies that the minimum value for these water bodies should be 3 mg/L.  It is reasonable to use the 5 mg/L value to screen the water quality data for large designated segments.  SRA feels the 3 mg/L value is a more realistic level for small unclassified streams and is in agreement with the established standards.  While natural conditions in small East Texas streams will result in occasional low dissolved oxygen levels, biological sampling conducted in these streams indicates a healthy aquatic community. 

High bacteria levels have also been detected in isolated areas throughout the Sabine Basin.  In some water bodies this appears to be the result of both point and non-point sources.  In other areas there are no known sources of sewage contamination and the bacteria levels are likely the result of wildlife.  Additional sampling for E. coli as well as Enterococci will help delineate between human and animal sources of bacteria.

For the 2004 assessment, the TCEQ identified water bodies with small datasets as partially supporting or not supporting designated uses, without regard for sample size, provided they meet the threshold number of exceedances and are otherwise representative.  This change in procedure resulted in several small streams being listed for impairments due to chronic toxicity in water.  Ambient toxicity tests in a few subwatersheds have indicated the possibility of the presence of toxic substances.  As stated in the Guidance for Assessing Texas Surface and Finished Drinking Water Quality Data, 2004, “Water bodies that have shown recurrent ambient water or sediment toxicity are candidates for more intensive special studies to confirm the occurrence of toxic conditions or nonsupport of aquatic life uses, and to determine the causes and sources of the toxicity.”  In every subwatershed in the Sabine Basin that has been included on the Draft 2004 303(d) List for chronic toxicity in water, SRA has conducted extensive additional biological sampling.  In each subwatershed there is no supporting evidence of toxic conditions.  Only the Little Cypress Bayou Subwatershed in Orange County showed impaired biological conditions and the data indicate the cause is excessive organic loading and not toxic substances.  The City of Orange is currently considering the annexation of this area and the waste load may eventually be diverted from this stream.

The SRA Water Quality Monitoring Program has evolved in response to the changing demands on the water resources in the Sabine Basin.  The current coverage of representative sampling sites provides water quality data for all key areas of the Basin.  The need for additional sampling will be evaluated and recommendations will be made to the Sabine Basin Steering Committee.  New sites will be selected on a priority basis to be determined by analysis of the Subwatershed Inventory and input from the Sabine Basin Steering Committee.




The 2003 Basin Summary Report, Sabine River Basin, Texas, was prepared in cooperation with the Texas Commission on Environmental Quality (TCEQ) under the authorization of the Texas Clean Rivers Act.

Introduction

The Sabine River Authority of Texas (SRA) was created by an act of the legislature in 1949, under Article XVI, Section 59 of the Texas Constitution as a Conservation and Reclamation District, a legal subdivision of the State of Texas.  As an agency of the State, SRA receives no appropriations and is not empowered to levy or collect any kind of taxes.  Operating funds are derived from the sale of water, hydroelectric power, water quality services, and recreational and land use permit fees.  The SRA was established with responsibilities to control, store, preserve, and distribute the waters of the Sabine River and its tributary streams for useful purposes.

The SRA has taken an active role in water quality matters since initial operational activities began in 1954; and, over the years, has expanded its services to meet increasing needs throughout the Sabine River Basin.  In the 1960's, the SRA participated in the establishment of the first stream standards for the State of Texas.  All available water quality data was compiled for the Sabine River from Sabine Lake to the headwaters.  This study was undertaken to help the Texas Water Quality Board (predecessor to today's Texas Commission on Environmental Quality[1]) establish the water quality criteria for Texas.  This study was also the beginning of the SRA’s water quality management program for the Sabine Basin.

The SRA reaffirmed this commitment to water quality protection when it constructed, equipped, and staffed a water quality testing laboratory in 1967.  In 1969, the laboratory began assisting wastewater dischargers in meeting their permit requirements for self-reporting.  The laboratory continues to provide water quality testing services to municipal and industrial customers as well as to the general public.

This initial program was expanded in 1972 to include the establishment of a surface water quality monitoring program.  Monitoring stations were established in coordination with state and federal agency programs to minimize duplication of effort and to provide the maximum amount of useful data.  The network of sampling stations and list of routinely tested parameters are reviewed on a regular basis to insure the program continues to meet state and basin needs.

These water quality laboratory and field programs have evolved into the present Environmental Services Division (ESD) which operates a modern, well-equipped water quality testing laboratory near Orange.  In June 1993, an Upper Basin Field Office (UBFO) was established to better serve the needs of the Upper Sabine Basin.  The SRA provides these services because they fulfill demonstrated needs and have proven to be beneficial for the SRA and its customers in managing and protecting the water resources in the Sabine Basin.

As part of its commitment to serve the evolving water resource needs of the Sabine Basin, SRA reorganized the Water Resources Branch (WRB) creating a new Division, Resource Management/ Project Development (RMPD).  The focus of the RMPD is to assist in water resource planning and development activities such as water supply, water resources protection, water quality issues, information management, and environmental services support.

Senate Bill 818, known as the "Texas Clean Rivers Act," was enacted in 1991 by the 72nd Legislature to ensure the comprehensive regional assessment of water quality in each watershed and river basin of the State.  The Texas Clean Rivers Act (TCRA) provides for river authorities, under the supervision of the TCEQ, to conduct regional assessments of their own watersheds.  These water quality assessments must include a review of:

n       wastewater discharges;

n       nonpoint source pollution;

n       nutrient loading;

n       toxic materials;

n       health of aquatic life;

n       public education and involvement in water quality issues;

n       local and regional pollution prevention efforts;

n       and other factors that affect water quality within the watershed.

 

The purpose of the assessment as defined by the TCRA is not to mandate exhaustive and detailed water quality studies, but to identify significant issues affecting water quality in each watershed (river basin) of the state and to provide sufficient information for the TCEQ, river authorities, and other governmental entities to take appropriate corrective action to maintain and improve water quality in each basin.  The TCRA also required the TCEQ to establish by rule the level of detail required for each watershed and river basin assessment.  The ongoing assessment program is known as the Clean Rivers Program (CRP[2]).

The SRA is the planning agency for all CRP activities in the Sabine Basin.  The SRA serves as the clearinghouse for all water quality data in the Sabine Basin and is responsible for analyzing the data to identify and prioritize water quality concerns and the causes of pollution.
