percent losses from diversion from Oak Creek to the distribution system
intake, there would be 684 acre-feet per year of yield to the Town's water
system during an average year. It should be noted that this estimate assumes
that the full 986.5 acre-feet of storage right is available each year.

Records to indicate the firm yield of the Town's water rights do not
ex i st. However, streamfl ow data from 1954, the dri est year on record, show
that the flow in Oak Creek at the town was not less than 0.5 cfs throughout
the year. Assuming that diversion of 0.5 cfs is possible year round, the firm
yield of the Town's water rights is conservatively estimated at 360 acre-feet.
This is a conservative estimate because it assumes that Sheriff Reservoir
water will not be available. No data exist that show the yield of Sheriff
Reservoir for 1954 or for other years.

The average annual yield of treated water from the Oak Creek water right
and Sheriff Reservoir storage is compared to the current demand in Table 1.
Table 1 shows that the yield from the Oak Creek right (0.5 cfs) and Sheriff
Reservoir storage provides 'over twice the current water demand for the Town.
At a minimum, Sheriff Reservoir supplies 25 percent of the current demand.
