The current reservoir elevation is 6500.0 feet, which amounts to 87 percent of live storage capacity. The total 2015 April-July inflow volume was 768,000 AF, or 106% of average.  While the seasonal inflow volume was above average, inflows to Fontenelle for the month of July were only 126,000 acre-feet (AF), or 71 percent of average. Recent daily inflow averages have ranged from 860 cfs to 1,020 cfs.

Reservoir releases have been held steady at 1,500 cfs since mid-July.  August weather conditions are expected to be relatively cool and dry, though strong storms continue to track southeast of the basin.  The Colorado Basin River Forecast Center has forecasted late summer inflows that are below average.  Releases will be reduced to 1,200 cfs on Monday, August 17, 2015. At the end of the month, releases will be further reduced to a winter baseflow level near 1,000 cfs. This is subject to change based on observed hydrology.
