Reservoir Monitoring Update

By May 6, 2018

TRWD staff continues to monitor conditions in the District reservoir watersheds 24 hours a day.  Runoff from the rainfall that fell last Thursday and Friday continues to pass through the system.  Overall the District’s area of interest received 1.5 to 2.5 inches of rainfall, see rainfall map below.   Richland-Chambers  Reservoir initiated controlled discharges yesterday.  They will continue will until the reservoir is at or near conservation level.  Eagle Mountain Lake is slightly above conservation which has activated low level discharges over the uncontrolled spillway.  With that being said, this will be the final update for this event.  Updates will resume if and when weather/reservoir conditions dictate.
