Reservoir Monitoring Update

By October 20, 2018

TRWD staff continues to monitor conditions in the TRWD reservoir watersheds 24 hours a day.  The National Weather Service (NWS) forecasts are calling for no rain in TRWD watersheds until Tuesday.  This is a welcome break from the rain.  Graphic-1 shows rainfall recorded at the TRWD reservoirs so far this month.  At least one of the reservoirs has recorded rainfall on 14 of the 19 days.

Current river conditions and forecasts from the NWS River Forecast Center can be found at the following links: West Fork Trinity River near JacksboroWest Fork Trinity River near Boyd, Trinity River at Trinidad, and Chambers Creek near Rice.

The latest reservoir projections follow:

  • Bridgeport continues to rise, but is not projected to fill at this time.
  • Eagle Mountain has crested from yesterday’s rainfall.  Discharges were increased this morning and the water level will recede over the weekend.
  • Lake Worth has crested from yesterday’s rainfall.  The increased discharges from Eagle Mountain are not expected to increase the pool level at Lake Worth.  However, the Eagle Mountain discharges will maintain the Lake Worth pool around elevation 594.9 ft-msl until discharges are reduced.
  • Richland-Chambers crested overnight.  Discharges were reduced this morning, but the pool is still expected to fall.
  • Cedar Creek continues to slowly fall. Discharges will continue until the pool has returned to conservation level.

Please be advised that projections are made barring additional rainfall and are subject to change.  TRWD reservoir operations are based on observed rainfall conditions.  Additional updates will be provided here if conditions dictate.  Please check back.
