The past few weeks of rain have left the TRWD watersheds near saturation and prone to runoff. In other words, the majority of the rain that falls in the TRWD watersheds will make its way to one of the reservoirs. With more rain in the upcoming forecast, be sure to monitor lake levels and continue following this Lake Level blog for any updates regarding the TRWD reservoirs. Current lake levels can be found in a variety of locations including TRWD.com, the TRWD watershed data viewer trwd.onerain.com, or download the TRWD Lake Level App for iOS or Android. You may also follow the National Weather Service (NWS) and the River Forecast Center (RFC) for the latest information regarding weather and river conditions, respectively.
TRWD continues to monitor reservoir conditions 24 hours a day. After a couple of dry days, rains are back to TRWD watersheds. Rainfall started overnight averaging 0.2 inches of rain to the Upper Trinity watersheds with totals of up to 0.7 inches. Rain is expected to continue throughout the day, with higher chances of heavy rain in the Northwest. See Graphic-1 for rain totals for the past 24 hours ending 7:00 am this morning. Increased chances of widespread heavy rain is expected tonight with a few showers lingering through Tuesday morning as a cold front slowly moves toward Southeast. Scattered storms and heavy rain is possible through the week with higher isolated amounts of 3-6″ through Sunday. See National Weather Service (NWS) today and tonight guidance below in Graphic-2. See NWS guidance for this week’s rainfall chances in Graphic-3.
Current reservoir conditions are shown below. Richland-Chambers and Cedar Creek continue to make flood discharges. Discharges from Eagle Mountain are continuing. Pool elevation is near conservation level, but it is expected to increase if forecasted rain materializes. Bridgeport remains below conservation level and no discharges are being made at this time, however its pool is expected to increase if additional rain falls. Staff will continue to monitor conditions and make discharges as needed to safely move excess water through the system. Updates to lake status and flood discharges will be posted here.
Please be advised that forecasts and projections are subject to change, and TRWD reservoir operations are based on observed rainfall conditions. The next update will come tomorrow morning, unless conditions dictate otherwise. Please check back.
