The current reservoir elevation is 6496.4 feet, which amounts to 79 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. Similarly, inflow for the month of August was limited to 53,000 AF, or 69 percent of average. Recent daily inflow averages have ranged from 540 cfs to 650 cfs.

Reservoir releases were reduced to 1,020 cfs on Monday, August 31, 2015. September weather conditions have been relatively warm and dry, and the Colorado Basin River Forecast Center has forecasted late summer inflows that are below average.  Depending on observed hydrology, releases may be further reduced to a winter baseflow level below 1,000 cfs.
