. . . 1121 The 1975 operating plan predicted a Project diversion of 36,000 acre-feet under the most probable conditions. The March 1, April 1, and May 1 forecasts based on Soil Conservation Service snow course data projected imports of 38,700 acre-feet, 46,500 acre-feet, and 43,500 acre-feet, respectively. Cool spring weather caused a delayed runoff and a large amount of water was lost due to evaporation. The actual diversion was 37,060 acre-feet as measured at the east portal of the Charles H. Boustead Tunnel. The maximum mean daily import was 481 c.f.s. on July 2 and a maximum instantaneous peak of 612 c.f.s. on July 1 and July 3. Turquoise Lake On October 1, 1974, the Turquoise Lake theoretical ownership was 51,986 acre-feet. The ownerShip of this water was as follows: CF&I, 13,668 acre-feet; Homestake, 7299 acre-feet; Highline Canal, 82 acre-feet; Catlin Canal, 92 acre-feet; and the Fryingpan-Arkansas Project, 30,845 acre- feet. All the water allocated to the Southeastern Colorado Water Conservancy District in 1974 was delivered. In November 1600 acre-feet of water was'released from Turquoise Lake for storage in Pueblo Reservoir. This additional water was needed to main- tain sufficient discharge capability for the Bessemer Ditch Outlet Works. In April and Mayan additional 12,800 acre-feet of water was transferred from Turquoise Lake to Pueblo Reservoir to finish filling the minimum pool and to store some water in the conservation pool in Pueblo Reservoir. Homestake Project started importing water in the middle of April and ended in late September. Their total imports amounted to just over 60,000 acre-feet. This import was not considered in the 1974-1975 Annual Operating Plan, so the inflow to Turquoise Lake was larger than anticipated. The Project allocation to the District was 25,000 acre-feet in 1975. This allocation was larger than in previous years because the Southeastern Colorado Water Conservancy District approved a plan in which the buildup of water for Project operations was deferred to later years. This allowed for more water to be utilized in current years with a larger buildup being accomplished when more diversion points are operating in the Collection System. Under this plan, as transmountain diversions increase with the added diversion points, the water will be used for Project buildup. The spring runoff in the Arkansas River was late; and, as a result, about one-fourth of the water allocated to the District was delivered in May. A small amount was delivered in June and July, and one-half was delivered in August. On September 30, 1975, about 2295 acre- feet of allocated water was undelivered.' Because of channel restrictions in Lake Fork below Sugar Loaf Dam, an exchange was made with Twin Lakes to deliver Homestake water during peak runoff. As a result, Twin Lakes was credited with 1677 acre-feet in the Project account in Sugar Loaf, which will be delivered during the next irrigation season. 5
