These data were fo:r the period 1981 through 1985. No <br />depletion data were received for the area above Navajo Reservoir. <br />There has been very little development, other than some minor <br />transbasin diversions, upstream from this reservoir. Depletions for <br />this area were assumed to be zero. Table 5.5 displays the annual <br />depletions for the major reservoirs upstream from Glen Canyon Dam. <br /> <br />Table 5.5.--1981-1985 annual depletions to major reservoirs upstream <br />from Glen Canyon Dam <br /> <br />Annual depletions <br /> <br />1981 59,800 68,600 96,400 161,900 <br />1982 60,900 69,900 85,100 152,600 <br />1983 64,400 78,200 116,900 177,400 <br />1984 56,900 66,900 83,800 148,800 <br />1985 71,400 81,400 97,400 154,900 <br />Total 312,900 364,700 479,600 795,6-00 <br />Average 62,600 72,900 95,900 159,100 <br /> <br />The monthly depletion distribution for these areas was assumed to be <br />similar to the distribution for the entire area above Glen Canyon. <br />Using the same monthly depletion distribution percentages as were <br />used for the depletions above Glen Canyon, the monthly 1985-level <br />depletions for these points are as presented in table 5.6. <br /> <br />66 <br />
