Reservoir Monitoring Update

By November 1, 2018

TRWD staff continues to monitor conditions in the TRWD reservoir watersheds 24 hours a day.   Graphic-1 shows the rainfall totals for yesterday across the TRWD watersheds.  The Richland-Chambers and Cedar Creek watersheds received the bulk of the rain, but Bridgeport received enough to fill later today.  Bridgeport has not been above conservation level since July 6, 2017.  This is a 482 day period during which the pool was as low as 7.06 feet below conservation.
