RE: December 2008 monthly Water Quality Report

The Environmental Services Field Offices conducted water quality monitoring in the Sabine Basin from December 8th through 15th. 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 variable with wide ranges in the temperatures. The highs ranged from the low 40s to the low 70s. Low temperatures ranged from low 30s to upper 40s. The Tidal stations received 2.57 inches of rainfall in the seven days prior to the sampling event. In a rare occurrence, the area received a measureable amount of snowfall the night prior to sampling.

 

Tidal Conditions - Surface salinities were found at all but the northern most Tidal station. The largest salinity value, 12.7ppt, was found at Blacks Bayou station BB1. 

Lower Sabine Basin (Toledo Bend Reservoir and Below)

 

Weather - Weather conditions in the Lower Basin were variable with a wide range of temperatures. The highs ranged from the low 40s to mid 70s. Low temperatures ranged from mid 30s to mid 60s. Toledo Bend received 2.91 inches of rainfall during the seven days prior to the sampling event. The Lower Basin also received a measurable amount during that seven day period.

Lake Level - The level of Toledo Bend Reservoir was recorded at 168.47 feet with 7404 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 Upper Basin was variable, with daytime highs in the low 40s to mid 70s with lows in the mid 20s to low 30s at Lake Tawakoni and at Lake Fork. Lake Tawakoni received 0.09 inches of rainfall and Lake Fork received 1.05 inches rainfall the week preceding the sample run.

Lake Level - The level of Lake Tawakoni was 433.13 feet msl with a 6 cfs release and the level of Lake Fork was 402.21 feet msl with a 7 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 2.57 inches of rainfall in the seven days prior to the sample event. In a rare occurrence, the area received a measureable amount of snowfall the night prior to sampling. Surface salinities were found at all but the northern most of the Tidal stations.  The largest salinity value, 12.7 ppt, was found at Blacks Bayou station BB1.  Heavy activity continues along the lower river in conjunction with underground pipeline construction.

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 890 cfs and the USGS flow at Sabine River station SR5 was 401 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 2.91 inches during the week prior to sampling.  The level of Toledo Bend Reservoir was recorded at 168.47 feet with 7404 cfs discharge at the time of sampling. Reservoir profiles indicated thermal mixing of the water column.  No profiles were taken at Toledo Bend station TB6H due to the weather conditions. The high winds and strong waves did not allow the boat to be launched at that site.

TOLEDO BEND RESERVOIR MAIN LAKE ABOVE THE DAM AT THE OLD RIVER CHANNEL

 

 

 

TOLEDO BEND RESERVOIR AT RAGTOWN


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 1,150 cfs and Sabine River Station SR14 had a flow of 907 cfs. Increased flows, increased turbidities and low secchi transparencies observed after 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 1.05 inches of rainfall the preceding seven days prior to sampling. The level of Lake Fork was 402.21 feet msl with a 7 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 1350 cfs at Sabine River Station SR17, 282 cfs at Sabine River Station SR19 and 75 cfs at Sabine River Station SR21. Increased flows, increased turbidities and low secchi transparencies observed at river stations after 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 0.09 inches of rainfall the preceding seven days prior to sampling. The level of Lake Tawakoni was 433.13 feet msl with a 6 cfs release at the time of sampling. Reservoir profiles indicated thermal mixing of the water column.
