RE: June 2008 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from June 9th through 11th. 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 highs from the mid 80s to the low 90s. Low temperatures ranged from the mid to upper 70s. The Tidal stations received 0.16 inches of rainfall in the seven days prior to the sampling event. 

Tidal Conditions - Surface salinities were not found at any of the Tidal stations. The largest salinity value, 2.2 ppt, was found at Blacks Bayou station BB1. 

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were hot with highs in the low 90s. Low temperatures ranged from the low to mid 70s. Toledo Bend received no rainfall during the seven days prior to the sampling event. 

Lake Level - The level of Toledo Bend Reservoir was recorded at 171.59 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 at most stations.

 

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 low 90s to mid 90s with lows in the mid 60s to mid 70s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 2.02 inches of rain and Lake Fork received 2.75 inches of rain the week preceding the sample run.

Lake Level - The level of Lake Tawakoni was 437.8 feet msl with a 230 cfs release and the level of Lake Fork was 403.58 feet msl with a 9 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 at deeper stations on Lake Tawakoni and Lake Fork.

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.

 

Sampling Conditions: The Tidal stations received 0.16 inches of rainfall in the seven days prior to the sample event.  Surface salinities were not found at any of the Tidal stations.  The largest salinity value, 2.2 ppt, was found at Blacks Bayou station BB1.  Heavy activity along underground pipeline construction continues along the lower portion of the Tidal Basin.

Segment 0501


Segment 0502 - Sabine River Above Tidal

Description: The designated segment includes the Sabine River from West Bluff in Orange County to the confluence with Caney Creek in Newton County. The largest tributary is Big Cow Creek (Segment 0513). This is largely a rural area with no major industries or cities.

Segment 0513 Big Cow Creek from the confluence with the Sabine River in Newton County to a point 4.6 kilometers (2.9 miles) upstream of R 255 in Newton County.

Sampling Conditions: The USGS recorded flow at Sabine River station SR2 was 3,840 cfs.

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 2,320 cfs and the USGS flow at Sabine River station SR5 was 2,700 cfs.

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 no rainfall during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 171.59 feet with 204 cfs discharge at the time of sampling. Reservoir profiles indicated thermal stratification of the water column at most sites.  Anoxic conditions were found at four lake sites at their deepest depths.

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 939 cfs and Sabine River Station SR14 had a flow of 681 cfs. Increased flows, increased turbidities and low secchi transparencies observed at all sites after heavy overnight rainfall.

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 2.75 inches of rain the preceding seven days prior to sampling. The level of Lake Fork was 403.58 feet msl with a 9 cfs release at the time of sampling. Reservoir profiles indicated thermal stratification of the water column at deeper sites. The USGS recorded flows were 294 cfs at Sabine River Station SR17, 278 cfs at Sabine River Station SR19 and 150 cfs at Sabine River Station SR21. Segments 0506 and 0515 had increased turbidities and low secchi transparences after heavy overnight rainfall.

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 2.02 inches of rain the preceding seven days prior to sampling. The level of Lake Tawakoni was 437.8 feet msl with a 230 cfs release at the time of sampling. Reservoir profiles indicated thermal stratification of the water column at deeper sites.
