These beoOme critical periods for <br />determining the firm annual yield. Based on a, . drought frequency <br />analy$is ,performed iIi. the screening phase of this study,' it is <br />estimatEid that.' the 1954~195 drought would occur once in 50 to 100 <br />years while the 19?7 drOught .would oocur once. in 30 to 50 years <br />dependingoIi. lodationof the stream. AccordiIi.gl,y, the, firm annual <br />yie;J.d presented in' thil3 ,report indicates, the saf.e amount, of water <br />that can be supplied during theSe two drought periods. <br /> <br />For each single reservoir, several reservoir capacities were <br />selected to develop a r_elationship between capacity and yield. The <br />results are summarized in Table 5.4. <br /> <br />wolford Mountain site Aland Wolcott were analYsedfor use as off- <br />stream storage sites. The Wolford Mountain Site AI analysis <br />considered two alternate diversion locations on the COlorado River, <br />one above the confluence with the Blue River and one below. <br />Wolcott Reservoir Could. store water from the Eagle River and the <br />Colorado Ri vel;' . The analysis of the combination reservoirs are <br />based on ~he fOllowing capacities. <br /> <br />5-9 <br />
