~] '• Sage Creek Dam failed in 1984 and has not been repaired. The failure and subsequent flood washed out the diversion dam for the Sage Creek Reservoir Outlet Ditch. The diversion dam was repaired and diversions have occurred in the past few years. The plan for augmentation proposed herein involves changing the water rights for the ' Sage Creek Reservoir and the Sage Creek Reservoir Outlet Ditch from irrigation to industrial purposes and adding places of storage and points of diversion. Limitations to the proposed changes will involve the historical use of the structures and historical irrigation practices. The ' following discussions describe the water rights and document the historical use of the water rights. This information was obtained from the State Engineer's office, discussions with Truman Manes (the former Water Commissioned, and a meeting with Bob Barnes on ' September 28, 1988. Water Rights Sage Creek Reservoir was decreed for irrigation purposes in Civil Action No. 1071 by ' the Routt County District Court on July 22, 1916. It was for 804 acre-feet with an appropriation date of June 30, 1908. Pertinent aspects of the water right are shown in Table 4 and this decree is included as Attachment A. ' The Bates Ditch water right was decreed for irrigation purposes on September 22, 1897 by the Routt County District Court. It was for 2.0 cfs with an appropriation date of June 19, 1897. Pertinent aspects of this water right are shown in Table 4 and this decree is shown in Attachment B. In Civil Action No. 1070 (July 14, 1916), the Court transferred 1.0 cfs from the Bates Ditch to the Sage Creek Reservoir Outlet Ditch. This decree is shown ' in Attachment C. In Case No. 91CW116, the remaining 1.0 cfs was abandoned. Diversion Records ' Diversion and storage records were obtained for the Sage Creek Reservoir Outlet Ditch, Dry Creek Ditch, and Sage Creek Reservoir from the State Engineer's office for 1965 through ' 1993. Descriptions of the diversion records follow. Sage Creek Reservoir Outlet Ditch. The ditch diverted streamflow and releases from ' Sage Creek Reservoir. The diversions averaged 232.3 acre-feet annually and ranged from none in several years to 865.8 acre-feet in 1975. The diversions normally began in late May to early June and continued into late August. There were no diversions from 1985 through ' 1990 due to the failure of Sage Creek Dam, and from 1991 through 1993 the ditch diverted small amounts of streamflow. The records are summarized in Table 7. The direct flow component of the diversions averaged 18.7 acre-feet annually as shown in Table 8. The ' average first day of direct flow diversion was June 8 and the average last day was July 18. The storage water diverted by the ditch averaged 213.6 acre-feet annually as shown in Table 9. The records do not segregate the diversions into direct flow and storage components for ' 1965-70 so the entire diversion was assigned to storage releases for this period. Dry Creek Ditch. The diversions by the Dry Creek Ditch averaged 129.8 acre-feet annually and ranged from none in 1981 to 410.6 acre-feet in 1985 as shown in Table 10. The diversion records include storage releases from Greasewood Flats Reservoir. The ' 5
