Services Field Offices conducted water quality monitoring in the Sabine Basin
from November 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 warm with
highs from the high 70s to the low 80s.
Low temperatures ranged from the low to mid 50s. The Tidal stations received 0.1 inches of
rainfall in the seven days prior to the sample event.
Tidal Conditions - Surface salinities were found at all but one of the Tidal stations. The largest salinity value, 20.9 ppt, was
found at station SRT1 at 9.7 meters.
Lower Sabine Basin
Reservoir and Below)
Weather - Weather
conditions in the Lower
Basin were warm with highs
from the mid 70s to the low 80s. Low
temperatures ranged from the low to mid 50s.
Toledo Bend received no rainfall during the week prior to sampling.
Lake Level - The level of Toledo Bend Reservoir was recorded at 167.68 feet with
204 cfs discharge at the time of sampling.
Toledo Bend has a conservation pool level of 172ft msl. Reservoir profiles indicated thermal
stratification of the water column.
Upper Sabine Basin
Reservoir, and the River above Toledo Bend)
Weather - Recent weather (previous
seven days) in the Sabine River Basin was warm, with daytime highs in the low
60s to low 80s and lows in the low 40s to low 60s at Lake Tawakoni and at Lake
Tawakoni and Lake Fork
received no rain the week preceding the sample run.
Lake Level - The level of Lake
Tawakoni was 436.04 feet msl with a 6
cfs release and the level of Lake
Fork was 402.75 feet msl
with a 19 cfs release at the time of sampling.
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.
