It is staff's opinion that the 21 years of stream -flow data analyzed is representative of average water- years. Existing Water Right Information Staff has analyzed the water rights tabulation and consulted with the Division Engineer's Office (DEO) to identify any potential water availability problems. There are several decreed surface diversions within the proposed lower instream flow reach. Currant Creek is not subject to calls from the Arkansas River due to a dry segment of stream below the lower terminus of the proposed instream flow segment; this results in a "Futile Call" on Currant Creek. Currant Creek is then self - administered by the local water user based on an agreement between the water users. Based on this analysis, staff recognizes that small portions of Currant Creek may experience water shortages during the irrigation season. However, return flows accrue quickly to the stream providing sufficient stream flows in the majority of the proposed lower instream flow reach to preserve natural environment to a reasonable degree without limiting or foreclosing the exercise of valid existing water rights, between the confluence with Thirtyone Mile Creek and the confluence with Cottonwood Creek.
