<br />Summary <br />The information contained in this report and the associated instream flow file folder forms the <br />basis for staff s instream flow recommendation to be considered by the Board. It is staff's <br />opinion that the information contained in this report is sufficient to support the fmdings required <br />in Rule 5.40. <br /> <br />Colorado's Instream Flow Program was created in 1973 when the Colorado State Legislature <br />recognized "the need to correlate the activities of mankind with some reasonable preservation of <br />the natural environment" (see 37-92-102 (3) C.R.S.). The statute vests the CWCB with the <br />exclusive authority to appropriate and acquire instream flow and natural lake level water rights. <br />In order to encourage other entities to participate in Colorado's Instream Flow Program, the <br />statute directs the CWCB to request instream flow recommendations from other state and federal <br />agencies. The Bureau of Land Management recommended this segment of Spring Creek to the <br />CWCB for inclusion into the Instream Flow Program. Spring Creek is being considered for <br />inclusion into the Instream Flow Program because it has a natural environment that can be <br />preserved to a reasonable degree with an instream flow water right. The BLM is very interested <br />in protecting stream flows because Spring Creek supports a fishery as wells as a diverse and <br />stable riparian community down to the floor of the Uncompahgre Valley. It is one of the few <br />perennial streams managed by BLM on the eastern side of Uncompahgre Plateau on which <br />diversions do not occur until the stream reaches the valley floor. <br /> <br />Spring Creek is 17.4 miles long. It begins at the confluence of the East Fork of Spring and the <br />Middle Fork of Spring Creek at an elevation of approximately 7,400 feet and terminates at the <br />confluence with the Uncompahgre River at an elevation of approximately 5,500 feet. The entire <br />5.5 mile segment addressed by this report is located on federal lands. Spring Creek is located <br />within Ouray and Montrose Counties Spring Creek generally flows in a northeasterly direction. <br /> <br />The subj ect of this report is a segment of Spring Creek beginning at the confluence of the East <br />and Middle Forks of Spring Creek and extending downstream to the Kenton Ditch (see Map). <br />The proposed segment is located southwest of Montrose. The staff has received only one <br />recommendation for this segment, from the BLM. The recommendation for this segment is <br />discussed below. <br /> <br />Instream Flow Recommendation(s) <br /> <br />BLM recommended 5.3 cfs, summer, and 2.6 cfs, winter, based on its May 22, 2002, and June 4, <br />2003, data collection efforts (see Appendix A). The modeling results from these survey efforts <br />are within the confidence interval produced by the R2Cross model. <br /> <br />land Status Review <br /> <br /> Total Length Land Ownership <br />Upper Terminus Lower Terminus (miles) % Private % Public <br />East & Middle Forks Kenton Ditch 5.5 7% 93 % <br />Spring Creek <br /> <br />Biological Data <br /> <br />The BLM has conducted field surveys of the fishery resources on this stream and have found a <br />natural environment that can be preserved.
