RE: APRIL 2011 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from April 11th through 13th. 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 warm with high temperatures from the upper 60s to mid 80s. Low temperatures ranged from upper 30s to low 70s. The Tidal stations received 0.03 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 but one of the Tidal Stations. The highest salinity value of 15.7 ppt was recorded at Sabine River station SRT1 at a depth of 9.0 meters.

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were warm with high temperatures from the upper 60s to upper 80s. Low temperatures ranged from the low 40s to upper 60s. Toledo Bend received 0.22 inches of rainfall during the seven days prior to the sampling event.

Lake Level - The level of Toledo Bend Reservoir was recorded at 164.43 feet with 204 cfs discharge at the time of sampling. Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated mixing of the water column. No samples or water quality were taken at Toledo Bend site TB6Q. Low water conditions prevented the boat from being launched.

 

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 warm, with daytime highs in the mid 60s to upper 80s with lows in the upper 30s to upper 60s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 0.39 inches of rainfall and Lake Fork received 0.91 inches of rainfall during the seven days prior to the sample run.

Lake Level - The level of Lake Tawakoni was 434.27 feet msl with a 6 cfs release and the level of Lake Fork was 399.75 feet msl with a 6 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 0.03 inches of rainfall in the seven days prior to the sampling event. Surface salinity values greater than 1 ppt were found at all but one of the Tidal Stations. The highest salinity value of 15.7 ppt was recorded at Sabine River station SRT1 at 9.0 meters.

Segment 0503


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 0.22 inches of rainfall during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 164.43 feet with 204 cfs discharge at the time of sampling. Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated mixing of the water column. No samples or water quality was taken at Toledo Bend site TB6Q. Low water conditions prevented the boat from being launched.

Segment 0504


Segment 0505 - Sabine River Above Toledo Bend Reservoir

Description: The designated segment includes the Sabine River from a point immediately upstream of the confluence of Murvaul Creek in Panola County to a point 100 meters (110 yards) downstream of US 271 in Gregg County. Segment 0505 is used extensively for water supply and contains the highest concentration of population in the Sabine Basin. The area includes a large section of the East Texas Oilfield as well as numerous industries.

Sampling Conditions: The (USGS recorded) flow at Sabine River Station SR11 was 269 cfs and Sabine River Station SR14 had a flow of 240 cfs.

Segment 0505


Segment 0506 - Sabine River Below Lake Tawakoni

Description: The designated segment includes the Sabine River from a point 100 meters (110 yards) downstream of US 271 in Gregg County to Iron Bridge Dam in Rains County. This is a largely rural area, but historically numerous dairies were located in the watershed. 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: Lake Fork recorded 0.91 inches of rainfall the preceding seven days prior to sampling. The level of Lake Fork was 399.75 feet msl with a 6 cfs release at the time of sampling. Reservoir profiles indicated mixing of the water column. The USGS recorded flows were

156 cfs at Sabine River Station SR17, 70 cfs at Sabine River Station SR19 and 20 cfs at Sabine River Station SR21. The USGS recorded flow for Big Sandy Creek was 44 cfs.
