Existing Water Right Information
Staff has analyzed the water rights tabulation and consulted with the Division Engineer Office
(DEO) to identify any potential water availability problems. There are no decreed surface
diversions within this reach of stream. Four decreed surface diversions are located downstream
of this segment: Alder Creek Ditch, Malcolm Ditch, B Clark Ditch and Means Ditch. Based on
this analysis, staff has determined that water is available for appropriation on Alder Creek,
between the BLM-National Forest boundary and the headgate of the Alder Creek Ditch, to
preserve the natural environment to a reasonable degree without limiting or foreclosing the
exercise of valid existing water rights.
