This is the Sabine River Authority
Water Quality Report for November 2006.
Water quality sampling was performed November 6th through
November 9th. Recent weather
(previous seven days) in the
Upper Sabine Basin Above Toledo Bend Including Lake Fork and Lake Tawakoni
Water quality parameter measurements at the Upper Basin sites were consistent with water of high quality for the November sample run. The level of Lake Fork was recorded at 397.97 feet msl with 33 cfs releases and the level of Lake Tawakoni was recorded at 426.01 feet msl with 6 cfs releases at the time of sampling. Station LT23C exceeded the stream standards numeric criteria for pH. SR22, SR21, LF20, SR19, BS9, SR17, SR16, SR15, SR14 exceeded the numeric criteria for the stream standard for E. coli. All of these sites exhibited increased flows, elevated turbidity and decreased secchi disk transparency due to runoff from area wide rainfall.
Lower Sabine Basin Including Toledo Bend to Morgan Bluff
The November monthly sampling results were indicative of water of high quality at most sites. The area received 1.37 inches of rainfall during sampling and the week prior. The level of Toledo Bend Reservoir was recorded at 164.95 feet with 174 cfs discharge at the time of sampling. Most reservoir stations were only slightly stratified with small dissolved oxygen and temperature differences throughout the water column. No anoxic conditions were found at any of the lake stations. The stream standards numeric criteria were not met at station TB8 for chloride, sulfate, and pH. Close to half of the stations in this section of the basin exceeded the criteria for bacteria, most likely due to runoff from the heavy rains received during the week of sampling.
