If the Members' of the <br />Regi.ona1 System were to acquire other sources of WIlW in addition to <br />thOllll :reoommended in this report, there llkel. y would be a need for an <br />Oak Creek ReseIVoir larger than 500 to 1,000 acre-feet to maximize the <br />System's willer supply, amone other reasons. <br /> <br />Fourth, depending on the decillion of the Regional System, the System <br />may wish to allow participation by others in the constIuctioo and use of <br />Oak Creek Reservoir. For example, the System might decide that it will <br />construct Oak Creek keservoit to a capacity of 1,250 acrp-fcet, and that <br />it will allow som~e else to use the other 1,000 acre-feet of the decreed <br />2,250 acre-feet of capacity, if that someone pays for the 'use of Its 1;000 <br />acre-feet. <br /> <br />VIII. SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS <br /> <br />A. Adequaey of Members Existin& Water Supplies. Without Raw Water <br />Storage In Oak CJ:tek Reservoir. <br /> <br />1. City of Florence <br /> <br />Florence has sufficient water supplieQ, without tbe use' of its <br />881.63 Union Ditch shares or its 67 Fremont County 'Ditch <br />shares, to satisfy itll water requirements through the year 2005. <br /> <br />When Florence's additional 881.63 Union Ditch shares and itB 67 <br />Fremont County Ditch share$ are added to the City's existing <br />supplies, Florence will have enough water for its year 2010 <br />average annuaJ requirement of 3,074 acre-feet, <br /> <br />19 <br /> <br />~ 009/015 <br />
