Reservoir Monitoring Update

By October 12, 2018
Rain Forecast | TRWD

TRWD staff continues to monitor conditions in the District reservoir watersheds 24 hours a day.    Much of the Eagle Mountain and Bridgeport watersheds have received 1/2 to 1 inch of rain since midnight.  The National Weather Service (NWS) continues to forecast anywhere from 2 to 8 inches of rainfall for the TRWD reservoir watersheds between now and Wednesday morning.  The NWS River Forecast Center‘s latest briefing is calling for a possibility of moderate to major river flooding in the Upper Trinity River basin, see below.  It should be noted that the locations in the Upper Trinity basin most likely to see these levels of flooding are downstream of Dallas as they are already experiencing elevated river levels from the rainfall earlier this week.  Sites in the far Upper Trinity basin such as Jacksboro and Boyd are more likely to see minor flooding, rather than moderate to major flooding.  Be sure to follow the River Forecast Center for the latest conditions at these locations.

Current conditions at TRWD reservoirs are shown below.   At the moment TRWD monitoring staff is not expecting TRWD reservoirs to fill, however the possibility cannot be ruled out.   Please be advised that forecasts are subject to change and TRWD reservoir operations are based on observed rainfall conditions.  Additional updates will be provided here if conditions dictate, please check back.
