Reservoir Monitoring Update

By May 15, 2023

The rain is winding down in our area and conditions are stabilizing. Yesterday’s rain was concentrated in East Texas and Richland-Chambers and Cedar Creek received 0.6″ and 1.1″, respectively. Bridgeport and Eagle Mountain got little to no rain. See Graphic-1 for rainfall totals over the past 24 hours.

Graphic-2 shows the accumulated rainfall for this event (starting Wednesday morning to today). The watershed average for TRWD lakes ranged from 1.2″ to 2.2″. The northern part of the West Fork system and parts of the Cedar Creek watershed received the heaviest rain.

The flood threat at Richland-Chambers has passed, since we are not expecting the lake to fill at this time. However, the pool is only 0.46 ft below conservation (315 ft). The right amount of rain in the right location could push the lake above conservation. Discharge operations continues at Cedar Creek. The pool is currently 0.11 ft above conservation (322 ft) and pool is expected to recede soon, barring additional rainfall. Flood discharges at the East Texas lakes will be adjusted accordingly to return the lakes to conservation level.

Graphic-3 below shows a map of rainfall expected in the TRWD watersheds over the next five days. There are small chances of rain multiple days during the workweek. Additional 0.3″ to 0.5″ are expected across TRWD watersheds. See Graphic-4 for NWS Guidance for additional details on the next system entering the area.
