Photos: Fontenelle Dam and Reservoir, August 2021

This page features imagery of Fontenelle Reservoir along the Green River in southwestern Wyoming.

Created by Fontenelle Dam, a 139-foot earthfill dam, Fontenelle Reservoir has a storage capacity of 345,000 acre-feet at full capacity. Although it was initially created to provide Green River water for irrigation, this unit of the Colorado River Storage Project now primarily serves as a storage reservoir.

In November 2021, the Wyoming Legislature’s Select Water Committee began drafting a stand-alone bill that would fund new dam, reservoir and irrigation projects. If passed, the bill would allocate $25 million to reinforcing Fontenelle Dam to increase its usable capacity.

This would not be the first dam reinforcement project conducted on Fontenelle Dam. In 1965, a significant leak prompted an emergency release of water to prevent the dam from failing. The release flooded downstream areas and damaged homes. In 1985, an evaluation determined that the dam was notably distressed and an emergency drawdown drained the entire reservoir. Both episodes prompted repairs and new construction.
