Subject: Gunnison River Whitewater Course — Case No. 02CW38
Dear Cynthia:
This letter report presents my opinions regarding water availability and administration
issues concerning the water rights application for the proposed Gunnison Whitewater Course filed
in Case No. 02CW38. Gunnison County is in the process of developing a Whitewater Park located
just west of the town of Gunnison where Highway 50 crosses over the Gunnison River as shown in
Figure 1. The Board of County Commissioners of the County of Gunnison and the Upper Gunnison
River Water Conservancy District (UGRWCD) entered into an intergovernmental agreement dated
March 26, 2002. One of the results of this agreement is that the UGRWCD is responsible to "file
and diligently pursue an application for water rights for the Whitewater Park ". This letter report was
prepared for the UGRWCD to support its water rights application in Case No. 02CW38.
Description of Whitewater Park
The Gunnison River Whitewater Course is part of the planned Gunnison River Whitewater
Park designed by Mr. Gary M. Lacy of Recreation Engineering and Planning. The future
Whitewater Park would include a parking area, trails, restroom facilities, and a Whitewater Course.
A conceptual plan of the Whitewater Park is shown in Figure 2. The major planned feature of the
Whitewater Park is the Whitewater Course that would be constructed within the existing banks of
the Gunnison River. The Whitewater Course is located approximately 150 miles upstream of the
stateline.
The Whitewater Course will be made up of six structures (three dams and three offset
deflector structures) which are designed to control, concentrate, and direct flow around boulders
and through self- scouring pools and holes to cause waves, directional current changes, and other
whitewater features that are used by kayakers and other boaters for recreation. A description of
these structures is included in the water rights application for the Whitewater Course as presented
in Appendix A. The Whitewater course will extend approximately one - quarter mile within the bed of
the Gunnison River. Mr. Lacy designed the course for a range of flows between 250 cfs and 2,000
cfs
