1037 . through the lake. No storage by exchange for the Pueblo Water Board ,is foreseen in 1974. That part of the Busk-Ivanhoe imports belonging to the High Line Canal Company was considered stored in Turquoise Lake under interim agreement. Releases to High Line Canal Company was assumed to be of the same quantity and pattern as occurred in 1973. CF&I Steel Corporation stores native inflow in the winter months up to l7,400 acre-feet under that corporation's 1902 storage right. Releases of CF&l water were assumed to be the same as those occurring in 1973. Fryingpan-Arkansas project imports are based On a probability study, exhibit 2. Those imports are estimated to be as follows: reason- able minimuni, 19,OOO acre-feet; most probable, 36,000 acre-feet; and reasonable maximum, 55,000 acre-feet. Water for the inactive pool in Pueblo Reservoir, 30,000 acre-feet, is to be delivered beginning December l5, 1973. The transmission loss between Turquoise Lake and Pueblo Reservoir is considered to be lO percent, therefore, 33,300 acre-feet ,of project water was considered released for this purpose beginning in December 1973. Two sets of criteria were considered in the accomplishment of this transfer. In one, assuming a mild winter, all of the 33,300 acre- feet was released from Turquoise Lake. Under the other criteria, a severe winter with resulting channel icing problems, all of the 33,300 acre-foot release was made from Twin Lakes and repayment made to Twin Lakes with a release beginning in the middle of April. It was assumed that this exchange release would be made at a rate of 365 c.f.s. as long as channel capacity [in Lake Fork below Sugar Loaf Dam remained to handle a flow of this magnitude. Safe channel capacity in Lake Fork below Sugar Loaf Dam for the sake of these computations was considered to be 400 c.f.s. . The amount of water considered delivered to the Southeastern COlorado Water Conservancy District was 36,000 acre-feet under most probable conditions, 24,800 acre-feet under reason~ble minimum conditions, and 37,lOO acre-feet under reasonable max~mum conditions. Delivery under reasonable minimum conditions was l~mited only by the amount required to keep an inactive pool in Turquoise Lake. Channel restric- tions below Sugar Loaf Dam li~ited the delivery under reasonable maximum conditions. Under the latter condition, it is quite possible that additional project water would be delivered to the Conservancy District early in the following year. There was 2,400 acre-feet of allocated water remaining at the end of the 1973 water year and this was considered to be delivered in Octobe~ 1973. . 18
