GEORGETOWN LAKE UPDATE  May 5, 2017

This morning the lake water level sits at 6428.69 feet, slightly less than a foot below the spillway crest. Outflow is set at about 24 cfs, down from 45 cfs for the past several days. Peterson Meadows/Warm Springs snow water equivalent is at 119% of normal this morning, and we are right at the normal annual peak of snow water accumulation. Storms are forecast at the lake for the next several days.

The lake ended April with a water surface elevation of 6428.73, losing 119 acre feet through the month with outflow averaging 39 cfs. Calculations show that April inputs (precipitation, ground water, surface water) were right at 37 cfs, which is about 110% of normal for the month. The April 30 elevation is very near the normal of 6428.80 feet.

The Boulder Creek hydrograph is indicative of small stream response in the area, including inflows to the lake from North Fork Flint Creek. Boulder Creek flows have been below normal, but with warm weather and additional precipitation, expect flows to increase quickly. North Fork Flint Creek and lake inputs will follow, but on a smaller scale.

The NRCS just published the May Water Supply Outlook and it looks favorable for Flint Creek. Right now, the best estimate (50% chance of exceedance) is for 124% of normal water volume passing the USGS gage, Flint Creek near Southern Cross. The attached JPG shows model output using these parameters. Note the especially high outflow average for June and elevated outflows through the year.

With the snow pack pretty much in place, the biggest factor now affecting runoff and hydrograph behavior is air temperature. Reservoir outflow may require careful monitoring and increases depending on air temperatures (both day and night) and the possibility of rain or rain-on-snow events.

Thanks, Dave
