This Executive Summary to the 2003
Basin Summary Report,
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
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
As part of its commitment to serve the evolving water
resource needs of the
The SRA uses a
watershed approach to assess water quality conditions in the
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
