Green Mountain Reservoir, a historically significant body of water, is nestled in Summit County, Colorado, near the northern end of the county along the Blue River, approximately 13 miles southeast of Kremmling. A significant part of the Colorado-Big Thompson Project (C-BT), a water diversion project approved by President Franklin D. Roosevelt in 1937, is the reservoir created by the Green Mountain Dam. This project, a testament to human ingenuity, was designed to divert water from the Colorado River to the Front Range cities for agricultural and municipal purposes, and Green Mountain Reservoir plays a crucial role in balancing this water diversion.
The Green Mountain Dam was constructed between 1938 and 1943 by the United States Bureau of Reclamation. It stands at 309 feet (94 meters) high and helps store up to 153,000 acre-feet (189,000,000 cubic meters) of water. At its maximum capacity, the reservoir covers a surface area of approximately 2,125 acres and reaches 7,950 feet (2,420 meters) above sea level. The dam’s power plant can generate up to 21,000 kilowatts of electricity, contributing significantly to the region’s energy needs and powering nearly 60,000 homes annually.
Green Mountain Reservoir is a practical structure and a popular recreational destination. The reservoir and surrounding areas offer a variety of activities for outdoor enthusiasts. Fishing is particularly popular, with the lake home to species such as brown trout, rainbow trout, lake trout, and kokanee salmon. The clear, cool waters of the reservoir provide an excellent habitat for these fish, making it a favored spot for anglers.
Boating is another major draw, with two boat-launch facilities available for use. The reservoir accommodates various watercraft, including powerboats, pontoons, and fishing boats, with rentals available from local marinas. Additionally, the lake features a designated swim beach, providing a safe and enjoyable spot for swimming during the warmer months.
Camping is well-supported around Green Mountain Reservoir, with six campgrounds offering 208 campsites. These campgrounds have picnic areas, public restrooms, and parking facilities. While these campgrounds are closed in winter due to snow and ice, they are highly popular during the summer, providing a perfect base for exploring the surrounding area.
Trails that provide picturesque views of the reservoir and its mountainous surroundings make hiking and nature hikes easier. The Green Mountain Reservoir Trail, running along the lake’s western side, is particularly popular among hikers and cyclists. The trail provides access to various natural features and is a great way to experience the area’s beauty up close.
Green Mountain Reservoir is not just a summer destination; it’s a year-round paradise for outdoor enthusiasts. Even during the colder months, the reservoir beckons with its winter activities. The lake freezes over, transforming into a destination for ice fishing. The surrounding snow-covered trails are ideal for snowmobiling, cross-country skiing, and snowshoeing, ensuring the reservoir remains a year-round destination for outdoor recreation. Whether it’s the vibrant colors of summer or the serene white of winter, the Green Mountain Reservoir is always ready to welcome you.
Green Mountain Reservoir is a testament to effective multi-purpose infrastructure. It balances water storage for agricultural and municipal use with recreational opportunities and support for local wildlife. Its scenic beauty and well-maintained facilities make it a beloved spot for locals and visitors seeking to enjoy Colorado’s natural splendor.
