Summery heat causes river to surge

EAGLE RIVER – Back-to-back days of 80-plus degree weather – with 90 downvalley – has primed the runoff pump in area rivers, which suddenly have become bank full.The rapidly-melting snowpack in area hills pushed Eagle River levels up 50 percent – from 860 cubic feet per-second Thursday at Avon to 1,260 Friday.That’s just a bit better than the mean flow at Avon, 1,175 cubic feet per-second, and close to the maximum of 1,600. The former is enough water over 24 hours to supply the annual water needs of 9,500 people.Snowpack statistics compiled by the Eagle River Water and Sanitation District show the snow at 90 percent of average. The peak flows probably won’t happen for more than a week. In a typical year, water experts said the peak runoff in the Eagle River typically occurs during the first week of June.Slightly cooler weather over the weekend should slow the rate of meting.Staff Writer Cliff Thompson can be reached at 949-0555, ext. 450, or, Colorado
