City of Aspen water officials are now working to update the city’s comprehensive water management plan and the process could inform future decisions about potential new dams, reservoirs and hydro power plants.
The $511,000 contract is seen by city officials as a way to help protect the city’s future diversion and storage projects from being called out by downstream water owners.
Wild and Scenic status, which ultimately requires an act of Congress to obtain, prevents a federal agency from approving, or funding, a new dam or reservoir on a Wild and Scenic-designated river.
Trees on a dam are considered a hazard as their roots can cause the dam to leak and high winds could blow the trees over, leaving a big hole where the roots were.
The upper ends of both Castle and Maroon creek valleys would be the sites of two new city of Aspen water storage reservoirs and dams, under 47-year-old conditional water rights that the city has continued to keep alive.
Was the city manipulating a federal process in the name of public safety?
A state dam safety engineer is requiring the city of Aspen to cut down 25 trees on the Thomas Reservoir dam and said the trees may already have caused “dam safety problems.”

The approach used by the city of Aspen to gain federal approval for a proposed hydropower plant was cited as a bad example by a critic of the project in testimony last week before a House subcommittee on energy and power in Washington, D.C.
The location is below the city’s diversion dam and its irrigation ditches, and above the location of the proposed hydropower plant’s tailrace where diverted water is to be returned to the stream.
