Reservoir Monitoring Update

By May 30, 2021

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, the TRWD watershed data viewer, 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.  No rain was recorded in TRWD service area in the last 24 hours. The weather is expected to be dry throughout the day with a slight chance of rain in the evening in the Northwest. A wet Memorial Day is expected as storms arriving from the West are possible tomorrow morning and chances linger in the afternoon. Increased chances of widespread heavy rainfall in the night are expected. Rain is still possible through the week with higher chances on Tuesday. See National Weather Service (NWS) guidance below in Graphic-1.

Current reservoir conditions are shown below.  Richland-Chambers and Cedar Creek continue to make flood discharges. Discharges from Eagle Mountain are continuing. Pool elevation has decreased and is expected to remain near conservation level, unless additional rain occurs. Bridgeport remains below conservation level and no discharges are being made at this time.  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.
