The Environmental
Services Field Offices conducted water quality monitoring in the Sabine Basin
from December 10th through the 12th. 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 mild with
highs from the low 60s to the upper 70s.
Low temperatures ranged from the low 30s to the upper 60s. The Tidal stations received 0.05 inches of
rainfall in the seven days prior to the sample event.
Tidal Conditions - Surface salinities were found at all but two of the Tidal stations. The largest salinity value, 15.1 ppt, was
found at Sabine River station SRT1A at 10.6
meters.
Lower Sabine Basin
(Toledo Bend
Reservoir and Below)
Weather - Weather
conditions in the Lower
Basin were mild with
highs from the low 60s to the low 80s.
Low temperatures ranged from the mid 20s to the mid 60s. Toledo
Bend received 0.18 inches of rainfall during the week prior and during sampling.
Lake Level - The level of Toledo Bend Reservoir was recorded at 167.73 feet with
204 cfs discharge at the time of sampling.
Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated thermal mixing
of the water column.
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
50s to low 80s with lows in the upper 20s to mid 60s at Lake
Tawakoni and at Lake Fork. Lake
Tawakoni received 0.04 inches of rain
and Lake Fork received no rain the week preceding
the sample run.
Lake Level - The level of Lake
Tawakoni was 435.47 feet msl with a 6
cfs release and the level of Lake
Fork was 402.53 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 thermal mixing of the water column at Lake Tawakoni
and Lake Fork.
