I I I I I I I I I I I I I I I I I I I Alternative No.1: Cost $622,000 Alternative No. 1 is for rehabilitation of the existing dams to attain the decreed water level of Gage Height 24.0. The dam is at 3:1 slopes and the location of the spillway is between the two dams near the east abutment of the West Dam. The total project cost was estimated at $622,000 and an increase in storage of 1532 acre-feet is realized with the rehabilitation. The Total Project Cost including interest: $622,000 x 0.07501 x 40 = $1,866,249 The Cost per acre-foot of water storage gained is: $1,866,249 + 1532 = $1218 I acre-foot The annual cost for the 40 year project loan: $1218 + 40 years = $30.45 I acre-foot I year The value of the water storage gained: 1532 acre-feet x $1,000 = $1,532,000 If the value of the wate~ is evaluated in terms of the crop production produced by the ir~igated land versus dry land farming, the water stored in Reservoi~ No. 2 would be worth $615,910- $240,638 = $375,272 per yea~ as shown by the analysis in Table VII-I. Thus the cost of the ~ehabilitation is worth two years of irrigated crop production. As previously stated this figure assumes a total loss of ability to irrigate the 3400 acres served by No.2. This is not the true case but is a good comparison to show the true worth of water erom a production standpoint. Alternative No.2: Cost $689,860 / Alternative No. 2 is for rehabilitation of the existing dams to attain the decreed max~mum water level of Gage Height 24.0 feet. The dam is at 4:1 upst~eam slopes, 3:1 downstream slopes, and the spillway at the West pam location. The total project cost was estimated at $689,860 and an increase in storage of 1532 acre- feet is realized. The Total Proiect Cost including interest: $689,860 x 0.07501 ~ 40 = $2,069,856 The Cost per Acre-foot ot water storage gained is: $2,069,856 + 1532 = $1351 I acre-foot VII-3
