Summary The information contained in this report and the associated instream flow file folder forms the basis for staff s instream flow recommendation to be considered by the Board. It is staff s opinion that the information contained in this report is sufficient to support the findings required in Rule 5.40. Colorado's Instream Flow Program was created in 1973 when the Colorado State Legislature recognized "the need to correlate the activities of mankind with some reasonable preservation of the natural environment" (see 37-92-102 (3) C.R.S.). The statute vests the CWCB with the exclusive authority to appropriate and acquire instream flow and natural lake level water rights. In order to encourage other entities to participate in Colorado's Instream Flow Program, the statute directs the CWCB to request instream flow recommendations from other state and federal agencies. The Bureau of Land Management (BLM) recommended this segment of Roc Creek to the CWCB for inclusion into the Instream Flow Program. Roc Creek is being considered for inclusion into the Instream Flow Program because it has a natural environment that can be preserved to a reasonable degree with an instream flow water right. The BLM is very interested in protecting streamflows because Roc Creek provides important habitat for sensitive fish speCIes. . Roc Creek is a tributary of the Dolores River, and the portion of the creek within Colorado is approximately 13.0 miles long. Roc originates on the east side of the La Sal Mountains in Utah at approximately 10,700 feet, and terminates at the confluence with the Dolores River at an elevation of approximately 4900 feet. The reach in Colorado is located primarily on federal lands, with the exception of 2.75 miles on private lands near Garvey Gulch. The creek is located in Montrose County. The total drainage area of the creek is approximately 87.5 square - 2 -
