Wayne N. Aspinall Storage Unit

Curecanti National Recreation Area is administered by the National Park Service (NPS) through a February 11, 1965, Memorandum of Agreement between the NPS and the U.S. Bureau of Reclamation (BOR) and is part of the National Park System.

Blue Mesa Reservoir, Morrow Point Reservoir, and Crystal Reservoir make up the Wayne N. Aspinall Storage Unit, named after the Colorado congressman instrumental in implementing the project.

The Wayne N. Aspinall Unit is one of the four main units of the Colorado River Storage Project (UCRSP). The other large dams in this project include the Navajo Dam (New Mexico), Flaming Gorge Dam (Utah), and Glen Canyon Dam (Utah). The primary purpose of this project is to provide water storage to the Upper Colorado River Basin states of Colorado, Wyoming, New Mexico, and Utah.

The three dams in Curecanti each serve a specific purpose and work as a system to store water, produce electricity, and regulate water flow for downstream irrigation, flood control, and habitat mitigation. The creation of dams undoubtedly impacted the Gunnison River and surrounding landscapes; native desert and shrubland were repurposed for agricultural use and the river channel disappeared beneath a reservoir.

There are currently no tours offered for any of the three dams within Curecanti National Recreation Area.

Blue Mesa Dam

Blue Mesa Dam is an earth fill embankment with a structural height of 390 feet, a crest length of 785 feet, and a volume of 3,080,000 cubic yards of materials. It was the first large dam built on the Gunnison River. Finished in 1965, Blue Mesa Dam created Blue Mesa Reservoir. Blue Mesa Reservoir is 20 miles long with 96 miles of shoreline. While Blue Mesa Dam does produce hydroelectricity, its primary purpose is water storage.

Blue Mesa Dam can be viewed from the Blue Mesa Dam Overlook on CO Highway 92, approximately 1 mile from the junction with U.S. Highway 50.

Morrow Point Dam

Morrow Point Dam was completed in 1967 and lies 12 miles below Blue Mesa Dam. This dam created a deep, narrow reservoir between the steep walls of the Black Canyon. The dam is a concrete, double curvature, thin arch dam rising 469ft. high. It was the first dam of its type built by the Bureau of Reclamation. The primary function of Morrow Point Dam is the production of hydroelectricity. With two 83,000kw generators, its power capacity is 172,000kw - almost twice the power capacity of Blue Mesa Dam.

Crystal Dam

Crystal Dam was completed in 1976 and lies six miles below Morrow Point Dam. Like Morrow Point, Crystal Dam is a concrete, double curvature, thin arch dam. Approximately 2 miles below the dam is the eastern boundary of Black Canyon of the Gunnison National Park; the Gunnison River continues from there. The purpose of Crystal Dam is to stabilize and regulate the flow of water through the national park. Crystal Dam also produces some hydroelectricity as a secondary function.

Overlooks
Crystal Dam can be seen from the end of the East Portal Road.
