RE: December 2011 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from December 5th through the 7th. 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 cool with high temperatures from the mid 40s to mid 70s. Low temperatures ranged in the low 30s to upper 60s. The Tidal stations received 0.52 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 22.1 ppt was recorded at Sabine River Station SRT1C at a depth of 9.0 meters. E.coli was not tested at several Tidal sites due to interferences caused by the high conductivities. Enterococcus was still sampled at all sites.

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were cool. No temperature readings were recorded at the reservoir gage this month. Toledo Bend received 3.07 inches of rainfall during the seven days prior to the sampling event.

Lake Level - The level of Toledo Bend Reservoir was recorded at 159.96 feet with 501cfs 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 sites TB6Q, TB6LN and TB6R. Low water conditions prevented the boat from being launched. Additionally, no samples or water quality were taken at site TB6CN due to the fact that the site no longer represents reservoir conditions due to the drought, or at TB6A and TB6H because high winds and rough water would not allow a boat to be launched. Increased turbidity and E.coli and reduced secchi were noted downstream to due runoff from the recent rains

 

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 cool, with daytime highs in the mid 40s to low 70s and with lows in the upper 20s to low 50s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 2.79 inches of rainfall and Lake Fork 3.28 inches of rainfall during the seven days prior to the sample run.

Lake Level - The level of Lake Tawakoni was 430.31 feet msl with a 6 cfs release and the level of Lake Fork was 395.58 feet msl with a 45 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 mixing 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 0.52 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 22.1 ppt was recorded at Sabine River Station SRT1C at 9.0 meters. E.coli was not tested at several Tidal sites due to interferences caused by the high conductivities. Enterococcus was still sampled at all sites.

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 998cfs. Increased turbidity and E.coli along with reduced secchi were noted at Big Cow Creek due to the recent rains.

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 1,260cfs and the USGS flow at Sabine River station SR5 was 1,050cfs. Increased turbidity and E.coli along with reduced secchi were noted at most sites due to runoff from recent rains.

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 3.07 inches of rainfall during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 159.96 feet with 501 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 sites TB6Q, TB6LN and TB6R. Low water conditions prevented the boat from being launched. Additionally, no samples or water quality were taken at site TB6CN due to the fact that the site no longer represents reservoir conditions due to the drought, or at TB6A and TB6H because high winds and rough water would not allow a boat to be launched. Increased turbidity and E.coli and reduced secchi were noted downstream to due runoff from the recent rains

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 599 cfs and Sabine River Station SR14 had a flow of 355 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 3.28 inches of rainfall the preceding seven days prior to sampling. The level of Lake Fork was 395.58 feet msl with a 45 cfs release at the time of sampling. Reservoir profiles indicated mixing of the water column. The USGS recorded flows were

418 cfs at Sabine River Station SR17, 263 cfs at Sabine River Station SR19 and 155 cfs at Sabine River Station SR21. The USGS recorded flow for Big Sandy Creek was 141 cfs.
