Windy Gap Reservoir, reservoir in Grand County, Colorado

Windy Gap Reservoir is a large manmade lake in Grand County, Colorado, that stores water from the Colorado River. The basin sits in open landscape with mountains in the background and connects to nearby Lake Granby through a pumping system.

The lake was created in 1985 by building a dam that flooded a meadow. The project sparked debate over environmental impacts, and later efforts began to restore the damaged river section downstream.

The reservoir was created by damming a meadow and now serves as a place where water management and wildlife protection meet. Visitors experience how the site balances human needs with preserving the natural habitat for local animals.

The site is easily accessible from US 40 with a signed parking lot, restrooms, and drinking fountains available. Access requires a valid wildlife area pass for visitors over 16 years old, and dogs are permitted only in the parking area.

The Windy Gap Watchable Wildlife Area, on the reservoir's north side, has parking and picnic tables for visitors watching birds on the water. The reservoir is a diversion dam, and a nearby pumping station lifts water six miles to Lake Granby before it is pumped over the mountains to the Front Range.
