RE: March 2009 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from March 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 warm with highs from the mid 40s to the low 80s. Low temperatures ranged from low 40s to upper 60s. The Tidal stations received 2.44 inches of rainfall in the seven days prior to the sampling event. The area received some heavy rainfall in the weekend just prior to the sampling event.

 Tidal Conditions - Surface salinities were found at all but three of the Tidal stations. The largest salinity value, 14.6ppt, was found at Sabine River station SRT1C at a depth of 10.5 meters. 

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were warm with highs from the upper 40s to low 80s. Low temperatures ranged from mid 40s to low 70s. Toledo Bend received 5.58 inches of rainfall during the seven days prior to the sampling event, including very heavy rains just prior to sampling.  This heavy rain resulted in an increase in the turbidity, bacterial results, and lower Secchi values.

Lake Level - The level of Toledo Bend Reservoir was recorded at 170.13 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 at all lake 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 cool, with daytime highs in the low 40s to upper 70s with lows in the mid 30s to mid 50s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 3.26 inches of rainfall and Lake Fork received 3.66 inches rainfall the week preceding the sample run.

Lake Level - The level of Lake Tawakoni was 433.12 feet msl with a 6 cfs release and the level of Lake Fork was 402.73 feet msl with a 9.5 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 mixing of the water column at all 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 2.44 inches of rainfall in the seven days prior to the sample event.  The area received heavy rainfall the weekend before sampling. This rainfall resulted in increased turbidity, lower Secchi values, and higher bacterial results due to the amount of runoff . Good downstream flow was also observed in the river. Surface salinities were found at all but three of the Tidal stations.  The largest salinity value, 14.6 ppt, was found at Sabine River stations SRT1C at a depth of 10.5 meters.  Heavy activity continues along the lower river in conjunction with underground pipeline construction.

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 area received heavy rainfall several days prior to sampling. This rainfall resulted in higher than normal flows, increased turbidity, lower Secchi values, and higher bacterial results due to the amount of runoff. The USGS recorded flow at Sabine River station SR2 was 9530 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 area received heavy rainfall several days prior to sampling. This rainfall resulted in higher than normal flows, increased turbidity, lower Secchi values, and higher bacterial results due to the amount of runoff. The USGS recorded flow at Sabine River station SR3 was 6110 cfs and the USGS flow at Sabine River station SR5 was 1280 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 5.58 inches of rainfall during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 170.13 feet with 204 cfs discharge at the time of sampling. Reservoir profiles indicated thermal mixing of the water column.

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 6,460 cfs and Sabine River Station SR14 had a flow of 5,350 cfs. Increased flows, elevated turbidity and reduced Secchi transparency were observed due to recent rainfall runoff.

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 3.66 inches of rainfall the preceding seven days prior to sampling. The level of Lake Fork was 402.73 feet msl with a 9.5 cfs release at the time of sampling. Reservoir profiles indicated mixing of the water column at all Lake Fork stations. The USGS recorded flows were 4,770 cfs at Sabine River Station SR17, 3.610 cfs at Sabine River Station SR19 and 2,210 cfs at Sabine River Station SR21. Increased flows, elevated turbidity and reduced Secchi transparency were observed at river stations due to recent rainfall runoff.
