Reservoir Monitoring Update

By August 22, 2022

TRWD staff continues to monitor conditions at the reservoirs.  A lot of rain over the weekend and especially in the last 24-hours, see Graphic 1 for totals.  The bulk of the heavy rain in Tarrant County fell below the reservoirs meaning it will not make its way to Bridgeport or Eagle Mountain.  Cedar Creek received nearly than 10″ right at the lake and an average of 5.4″ in the watershed.  The dry watershed conditions are limiting the impacts of all this rain as a majority of the rain will be lost to infiltration.  Cedar Creek is expected to continue climbing and can could possibly reach as high as elevation 319.  That said,  Cedar Creek is not expected to fill at this time.  The same is true at the other TRWD lakes, Bridgeport, Eagle Mountain and Richland-Chambers are not expected to fill at this time either.  Keep up with lake levels at  or at the TRWD OneRain site  and remain weather aware by following the National Weather Service (NWS) River Forecast Center (RFC).  This will be the last post for this event.
