Park Staff Seeking Input On Lily Lake Dam Project

The Lily Lake Dam, located in Rocky Mountain National Park, has been rated a high-hazard dam by the U.S. Bureau of Reclamation. Failure of the dam is not imminent, and park staff are evaluating long term solutions; considering two options to reduce the risk, either repairing or removing the dam. Until a long term solution is implemented, the dam will be regularly inspected and monitored, and a pump has been purchased to lower the lake level in the event of a significant weather event.
The Lily Lake Dam is situated at the headwaters of Fish Creek, which flows into Lake Estes in Estes Park. Fish Creek is about 5 miles in length and the elevation difference between Lily Lake and Lake Estes is about 1,500 feet. If the dam were to fail, the ensuing floodwaters could result in the loss of life and property along Fish Creek. Repairs are needed to the dam to reduce the hazard, or the dam could be removed and the area restored to natural conditions.
Lily Lake, located along Highway 7, has become a popular recreational area in Rocky Mountain National Park. The lake sits in a beautiful mountain setting, surrounded by an accessible trail. The lake is a popular fishing spot and is stocked with greenback cutthroat trout, a federally listed threatened species.
Park staff are seeking the public’s input on two long term alternatives. Both repairing and removing the dam would involve several steps. The estimated cost of repairing the dam is approximately $1.4 million, with additional annual costs to maintain and monitor the dam. The estimated cost of removing the dam would be approximately $150,000. If the dam is removed, the resulting lake would be about 14 acres in surface area and would contain about 39 acre feet of water. If the dam remains in place, the lake would be about 17 acres in surface area and contain about 75 acre feet of water.
