prior to the sample event were warm.
High temperatures were in the upper 80s.
Low temperatures in the area ranged from the mid 60s to the low
70s. The tidal stations received 0.37
inches of rainfall in the seven days prior to sampling.
Tidal Conditions - Surface salinities were
found at all but one Tidal station. The
largest salinity value, 15.6 ppt, was found at Sabine
River station SRT1 at 10.2 meters.
Lower Sabine Basin
Reservoir and Below)
Weather - Weather conditions in the
Lower Basin prior to the sample event were
warm. High temperatures ranged from the

in the area ranged from the mid 60s to the low 70s. Toledo
Bend received 0.39 inches of rainfall during the week prior and during the
Lake Level - The level of Toledo Bend Reservoir was recorded at 168.02 feet with
174 cfs discharge at the time of sampling. Toledo Bend Reservoir stations
were stratified in vertical profile samples. Anoxic conditions were found
at several of the deeper lake sites below 6 to 10 meters.
Fork Reservoir, and the River Above Toledo Bend)
Weather - Recent weather (previous
seven days) in the upper Sabine River Basin was warm, with daytime highs in the upper
70s to low 90s and lows in the low 60s to low 70s at Lake

Tawakoni received no rain and Lake Fork
received 0.05 inches of rain the week preceding the sample run.
Lake Levels - The level of Lake Tawakoni
was 436.87 feet msl with a 6 cfs release with no rain recorded seven days prior
to sampling. The level of Lake
Fork was 403.2 feet msl
with a 19 cfs release with 0.05 inches of rain recorded seven days prior to
sampling. Lake Tawakoni
and Lake Fork Reservoir stations were stratified in vertical profile samples.
