Reservoir Monitoring Update – March 27, 2018

By March 27, 2018
Rainfall Accumulation | TRWD

TRWD staff continues to monitor conditions in the District reservoir watersheds 24 hours a day.  The past 24 hours have brought a varying amount of rainfall across the Lake Bridgeport and Eagle Mountain Lake watersheds.  A map displaying the radar-estimated rainfall depths along with rain gauge observations for the District area of interest is displayed below.  The greatest rainfall totals have been in the headwaters of the Lake Bridgeport watershed near Antelope.  This water will not make it to Lake Bridgeport for 2-4 days if it makes it at all due to infiltration and channel losses.  Elsewhere, there has been about an inch of rainfall.  This has not been enough to generate significant runoff at this time, but this could change and District staff will be watching the stream gauges closely over the next few days.  The eastern reservoirs have received little to no rain so far, but this is expected to change this afternoon through tomorrow afternoon according National Weather Service guidance.  Please check back during this event for further updates.
