<br />
<br />condition for municipal, industriel, and irrigation de~ands.
<br />
<br />The critical period in the analysis was from July 1952 through October 1956.
<br />
<br />During the critical period, the average annual diversion and release from Navajo
<br />
<br />Reservoir was 506,000 ecre-feet for municipal, industrial, and irrigation
<br />
<br />demands. This left 524,600 acre-feet in the conservation poo~ at the end of the
<br />
<br />critical period (4 years-4 months). Therefore, the San Juen River, through
<br />
<br />regulation provided by Navajo Reservoir, has the capability to meet the pro-
<br />
<br />jected Gallup-Navajo water demands.

<br />
<br />Based on the historical period of record (1906-1978), the CRSS natural flows,
<br />
<br />and hydrologic analysis, it appears that 5.8 KAY is a conservative estimate of
<br />
<br />the allowable limit of Opper Colorado River Basin depletions and there is no
<br />
<br />evidence to indicate that the 5.8 KAY figure should be changed. Colorado liver
<br />
<br />operation studies based on use of existing up-to-date hydrologic data and analy-
<br />
<br />sis, coupled with the estimated future Upper Basin depletions through the year
<br />
<br />2039 indicate that with the available storage afforded by tbe Colorado River
<br />
<br />Storage Project, tbe Upper Basin could meet its obligation for water delivery at
<br />
<br />Lee Ferry and still readily acco_odate the projected 69,000 acre-feet depletion
<br />
<br />for municipal and industrial uSeS in New Mexico.
