Reservoir Monitoring Update

By October 13, 2021

Weather Update

The next 48 hours is expected to be active in terms of rainfall across the State.  In the TRWD watersheds 3 to 4 inches of widespread rainfall is likely and isolated areas of heavier rain are not out of the question.  Graphice-1, below, from the National Weather Service (NWS) River Forecast Center (RFC) shows the latest thinking on rainfall amounts and the potential for river flooding.  The highest potential for river flooding is in Central Texas.  Watershed conditions in the TRWD area are such that a bulk of this rain can be absorbed into the ground without turning to runoff.  That said, large amounts of rain in a short period of time or rain directly a lake will be converted to runoff at a much higher rate.  Also be on the look out for flash flooding in the more urban locations.  Please follow our partners at the NWS and RFC for the latest weather and river conditions, respectively.

Reservoir Conditions

Current reservoir conditions are shown below.   All reservoirs are currently below conservation level meaning they are less than full.  Low level water supply release are on-going at Bridgeport and Eagle Mountain, these will be monitored and adjusted as conditions dictate.  Flood operations are not expected at this time; however, staff will continue to monitor conditions and take action as needed to safely move any excess water through the system. Updates to lake status and flood discharges will be posted here as needed.

Remember to check out on your smartphone or computer to view the latest observed lake levels and rainfall totals in the TRWD watersheds.

Please be advised that forecasts and projections are subject to change, and TRWD reservoir operations are based on observed rainfall conditions. Additional updates will be provided as conditions dictate.  Be sure to subscribe to receive e-mail notification of any new Lake Level Blog posts.  You can also follow @TRWD_News on Twitter to receive Lake Level blog notifications.
