Current Conditions

As of 7/13/26, the boat ramp is closed for public safety at Heeney Marina due to low water. Hand-launching of non-motorized vessels is allowed, but hand-launching motorized vessels is not permitted due to the risk of spreading aquatic nuisance species. Docked rental motorized boats are available for rent at the Heeney Marina.

Green Mountain Reservoir lies at the northern end of Summit County, Colorado along the Blue River near the town of Heeney. There are 6 campgrounds at the reservoir and a 7th campground is located along Cataract Creek adjacent to Eagles Nest Wilderness and various hiking trails.

The reservoir has boat-launch facilities and is a popular spot for motor boating, sailing, canoeing, and water skiing. Fishing is also primary recreational activity at the reservoir. Primary sport fish available are brown trout, rainbow trout, and salmon.

This area is bear country! Storage of food, garbage and bear attractants is required. Wilderness regulations apply in Eagles Nest Wilderness.
