The Penrose Water District purchased 224 acre feet from Beaver Park Water in 1978 for domestic use. Table 1 shows the monthly water provided by the ditch in the District's settling pond for treatment and sale to the District's customers in each month of 1977 and 1978. The contract to supply water to the Water District provides that it can draw up to 500 AF, from the ditch. The Penrose Water District has a projected 100% increase in water use in the next 10 years at present growth rates. The water requirements for the individual crops grown at Beaver Park are listed in Table 2. Included on the table are the average rainfall amounts to be expected at Penrose. The ability to supply water to the shareholders is limited by both theavailabili ty of water in Beaver Creek and by the carrying capacity of the pipeline laterals. As stated pre- viously, the original system design was based upon the de- livery of 1.5 acre feet per acre in four rotations of three days each. This design results in the delivery of 0.125 AF per day for each acre. The basic unit in the irrigated area is a 10-acre tract. The delivery boxes were equipped with 18-inch contracted weirs and the normal depth or "head" over the weir is ) inches or 0,61 cfs, In the common terms used by the water users, they refer to a )-inch "head" of water for) days on a 10 - acre tract, At present, the maximum delivery capabilities of the laterals is about 40 "heads" delivered at the turn- out points for the water users, When the water is delivered to the turn-outs, the canals and laterals are absorbing the delivery losses in the system, At a delivery rate of )0 "heads", the system can supply )00 acres in ) days, however it requires an average of 50 days
