RE:            August 2010 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from August 16th through 18th.  The results of the field monitoring are presented in this report and additional laboratory results will be included in the annual Sabine Basin Water Quality Report.

 

Sabine Basin Tidal (Including Tributaries)

 

Weather - Weather conditions in the Tidal Basin were hot with high temperatures from the low to mid 90s.  Low temperatures ranged from mid to upper 70s.  The Tidal stations received 1.22 inches of rainfall in the seven days prior to the sampling event. 

 Tidal Conditions –Surface salinity values greater than 1 ppt were found at all of the Tidal Stations.  The highest salinity value of 14.3 ppt was recorded at Sabine River station SRT1 at a depth of 10.0 meters.

  

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were hot with high temperatures from the upper 90s.  Low temperatures ranged from the mid to upper 70s.  Toledo Bend received 0.6 inches of rainfall during the seven days prior to the sampling event.

Lake Level - The level of Toledo Bend Reservoir was recorded at 167.65 feet with 204 cfs discharge at the time of sampling.  Toledo Bend has a conservation pool level of 172ft msl.  Reservoir profiles indicated stratification of the water column.

 

Upper Sabine Basin (Lake Tawakoni, Lake Fork Reservoir, and the River Above Toledo Bend)

 

Weather - Recent weather (previous seven days) in the Sabine River Basin was hot, with daytime highs in the low 100s to mid 90s with lows in the mid 70s to upper 70s at Lake Tawakoni and at Lake Fork.  Lake Tawakoni and Lake Fork recorded no rainfall the week preceding the sample run. 

Lake Level - The level of Lake Tawakoni was 435.8 feet msl with a 6 cfs release and the level of Lake Fork was 401.76 feet msl with a 15 cfs release at the time of sampling.  Lake Tawakoni and Lake Fork have conservation pool levels of 437.5 msl and 403 msl, respectively.  Reservoir profiles indicated stratification of the water column.

Segment 0501 – Sabine River Tidal

Description:  The designated segment includes the Sabine River from the confluence with Sabine Lake in Orange County to West Bluff in Orange County.  Although some areas are quite rural, this part of the Sabine Basin has two cities with populations greater than 5,000 and a variety of industries.

Segment 0508 – Adams Bayou Tidal.  The segment reaches from the confluence with the Sabine River in Orange County to a point 1.1 kilometers (0.7 miles) upstream of IH-10 in Orange County.

Segment 0511 – Cow Bayou Tidal.  The segment reaches from the confluence with the Sabine River in Orange County to a point 4.8 kilometers (3.0 miles) upstream of IH-10 in Orange County.

 

Sampling Conditions:  The Tidal stations received 1.22 inches of rainfall in the seven days prior to the sampling event.  Surface salinity values greater than 1 ppt were found at all of the Tidal Stations.  The highest salinity value of 14.3 ppt was recorded at Sabine River station SRT1 at 10.0 meters.

Segment 0504 – Toledo Bend Reservoir

Description:  The designated segment includes the Sabine River from Toledo Bend Dam in Newton County to a point immediately upstream of the confluence of Murvaul Creek in Panola County.  Although this area is largely rural, it includes two cities with populations greater than 5,000.  Murvaul Creek is a major tributary that enters upstream from the reservoir.

 

Sampling Conditions:  Toledo Bend received 0.60 inches of rainfall during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 167.65 feet with 204 cfs discharge at the time of sampling. Toledo Bend has a conservation pool level of 172ft msl.  Reservoir profiles indicated stratification of the water column.
