After rapidly lowering for the last several weeks to make room for snow runoff, water levels in Dillon Reservoir in Summit County Colorado will begin to rise again this week.

Denver Water announced Thursday that it's dropping outflow to the Lower Blue from 800 to 500 cubic feet per second.

The main reason for the change is that the runoff from the South Platte drainage has been considerably less than projected. The snow seems to be melting at a slower pace than originaly anticipated.

Denver water has reported that as a result it may have to bring more water through the Roberts tunnel than previously thought.

The change will improve fly-fishing conditions in the Blue River below the dam and bring water levels up at the Frisco marina.

Local outfitters said the decreased outflow won't affect commercial rafting trips on the Lower Blue.
