SABINE RIVER AUTHORITY OF TEXAS TO: FROM: RE: INTERESTED PARTIES ENVIRONMENTAL SERVICES DIVISION AUGUST 2013 MONTHLY WATER QUALITY REPORT The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from August 12 th through the 16 th. The results of field monitoring are presented in this report and additional results can be found at the Texas Commission on Environmental Quality (TCEQ) Surface Water Quality Monitoring Web Reporting site: http://www80.tceq.texas.gov/swqmisweb/public/index.faces Sabine Basin Tidal (Including Tributaries) Weather - Weather conditions in the Tidal Basin were hot with high temperatures from the upper 80s to mid 90s. Low temperatures ranged in the low to mid 70s. The Tidal stations received 1.46 inches of rainfall in the seven days prior to the sampling event. Tidal Conditions Surface salinity values greater than 2 ppt were found at five of the Tidal Stations. The maximum salinity value of 21.3 ppt was recorded at Sabine River Station SRT1C at a depth of 10.5 meters. Lower Sabine Basin (Toledo Bend Reservoir and the Sabine River downstream to Tidal) Weather - Weather conditions in the Lower Basin were hot with high temperatures from the mid to upper 90s. Low temperatures ranged in the low to mid 70s. Toledo Bend received 0.65 inches of rainfall during the seven days prior to the sampling event. Lake Level The level of Toledo Bend Reservoir was recorded at 168.11 feet with a daily average discharge of 204 cfs at the time of sampling. Toledo Bend has a conservation pool level of 172 feet msl. Reservoir profiles indicate thermal stratification of the water column. Upper Sabine Basin (Lake Tawakoni, Lake Fork Reservoir, and the Sabine River upstream of Toledo Bend) Weather - Recent weather in the Upper Basin was hot with daytime highs in the upper 90s to low 100s and with lows in the low 70s to upper 70s at Lake Tawakoni and Lake Fork. Lake Tawakoni and Lake Fork received no rainfall during the seven days prior to the sampling event. Lake Level - The level of Lake Tawakoni was 430.21 feet msl with a 6 cfs release and the level of Lake Fork was 397.63 feet msl with a 30.5 cfs release at the time of sampling. Lake Tawakoni and Lake Fork have conservation pool levels of 437.5 feet msl and 403 feet msl, respectively. Reservoir profiles indicate thermal stratification of the water column.

The major tributaries include: Segment 0514 - Big Sandy Creek from the confluence with the Sabine River in Upshur County to a point 2.6 kilometers (1.6 miles) upstream of SH 11 in Hopkins County. Segment 0515 - Lake Fork Creek from the confluence with the Sabine River in Wood County to Lake Fork Dam in Wood County. Segment 0512 - Lake Fork Reservoir from Lake Fork Dam in Wood County up to the normal pool elevation of 403 feet. Sampling Conditions: The Lake Fork Division Office recorded no rainfall during the seven days prior to sampling. The level of Lake Fork Reservoir was 397.63 feet msl with a 30.5 cfs release at the time of sampling. Reservoir profiles indicate thermal stratification of the water column. The USGSrecorded flows were 37 cfs at Sabine River Station SR17 (USGS #08020000 Sabine River near Gladewater, TX), 39 cfs at Sabine River Station SR19 (USGS #08019200 Sabine River near Hawkins, TX), and 3.4 cfs at Sabine River Station SR21 (USGS #08018500 Sabine River near Mineola, TX). The USGS-recorded flow at Big Sandy Creek (USGS #08019500 Big Sandy Creek near Big Sandy) was 2.5 cfs when samples were collected.
