Green Mountain Reservoir, one of the biggest reservoirs in Summit County, located in Summit County, is low this summer, but it’s not as low as in previous drought years. The reservoir is currently storing about 101,000 acre-feet of water — 32.9 billion gallons — James Heath, division engineer for the Colorado Division of Water Resources, said in an email. He noted that the reservoir is typically nearly full around this time of year. A full Green Mountain Reservoir is about 154,000 acre-feet of water, or approximately 50 billion gallons. However, Heath said in previous drought years like 2002 and 2012, there was less water stored in the reservoir than there is this year.
