RE: September 2012 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from September 10th through the 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 hot with high temperatures from the mid 80s to low 90s. Low temperatures ranged in the upper 50s to mid 70s. The Tidal stations received 0.14 inches of rainfall in the seven days prior to the sampling event.

 Tidal Conditions Surface salinity values greater than 2 ppt were found at all of the Tidal Stations. The maximum salinity value of 26.0 ppt was recorded at Sabine River Station SRT1 at a depth of 9.0 meters

Lower Sabine Basin (Toledo Bend Reservoir and the River below to Tidal)

 

Weather - Weather conditions in the Lower Basin were hot with high temperatures from the low 80s to upper 90s. Low temperatures ranged in the low 60s to upper 70s. Toledo Bend received 0.11 inches of rainfall during the seven days prior to the sampling event.

Lake Level The level of Toledo Bend Reservoir was recorded at 168.42 feet with 174cfs discharge at the time of sampling. Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated stratification of the water column at most sites.

 

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 mid 80s to low 100s and with lows in the mid 50s to mid 70s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 0.05 inches of rainfall and Lake Fork 0.04 inches of rainfall during the seven days prior to the sample run.

Lake Level - The level of Lake Tawakoni was 434.51 feet msl with a 6 cfs release and the level of Lake Fork was 399.46 feet msl with a 51.5 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 0.14 inches of rainfall in the seven days prior to the sampling event. Surface salinity values greater than 2 ppt were found at all of the Tidal Stations. The maximum salinity value of 26.0 ppt was recorded at Sabine River Station SRT1 at a depth of 9.0 meters

Description: The designated segment includes the Sabine River from a point immediately upstream of the confluence with Caney Creek in Newton County up to Toledo Bend Dam in Newton County. This is largely a rural area with no major cities and few industries. The two major tributaries include Bayou Anacoco and Bayou Toro that flow from Louisiana.

Sampling Conditions: The USGS recorded flow at Sabine River station SR3 was 1,130cfs and the USGS flow at Sabine River station SR5 was 241cfs.

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 0.11 inches of rainfall during the seven days prior to the sampling event. The level of Toledo Bend Reservoir was recorded at 168.42 feet with 174cfs discharge at the time of sampling. Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated stratification of the water column at most sites. One site change took place with this months sampling. Site TB6CN (SH 87 at Six Mile) was replaced by site TB6C (Six Mile boat lane 0.8km east of SH 87). The new site is accessed by boat and will be more representative of the Six Mile arm of the reservoir.

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 30 cfs and Sabine River Station SR14 had a flow of 56 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 0.04 inches of rainfall the preceding seven days prior to sampling. The level of Lake Fork was 399.46 feet msl with a 51.5 cfs release at the time of sampling. Reservoir profiles indicated stratification of the water column. The USGS recorded flows were

61 cfs at Sabine River Station SR17, 74 cfs at Sabine River Station SR19 and 5.4 cfs at Sabine River Station SR21. The USGS recorded flow for Big Sandy Creek was 8.7 cfs.

Segment 0506


Segment 0507 - Lake Tawakoni

Description: The designated segment includes the impounded Sabine River from Iron Bridge Dam in Rains County up to the normal pool elevation of 437.5 feet. Although much of this segment is rural, it contains one of the four largest cities in the Sabine Basin.

 

Sampling Conditions: Lake Tawakoni received 0.05 inches of rainfall the preceding seven days prior to sampling. The level of Lake Tawakoni was 434.51 feet msl with a 6 cfs release at the time of sampling. Reservoir profiles indicated stratification of the water column. Site LT23D (Kitsee Inlet near White Point Causeway) was replaced by site LT23DN (Waco Bay Equidistant from Finger and Spring Points).
