U01801 will mean enough water to irrigate all the irrigable areas on the reservations. This totals up to 453,315 acre-feet, which Judge Rifkind said is to be charged against the states in which the Indian lands are situated. (Of the total cited; 426,135 acre-feet are accounted for by Indian lands located in Arizona and thus are considered part of our 2,800,000 acre-feet allocation of main- stream water. It will not impair the proposed Central Arizona divet3ion. however. and, in any event, is certainly to be regarded as watel' consumed in Arizona, by Arizonans, and hence bene- ficial to Arizona's economy,) Judge Rifkind also recommended allocations totaling 69,839 acre-feet to the Havasu and Imperial waterfowl refuges, these likewise to be charged against the state,~ in which the uses occur. The Master declined to rule on other federal claims relating to tributaries of the Colorado and involving uses for national forests, recreation at'eas, parks, memorials, monuments and lands administered by the U.S. Bureau of Land Management. He held that there was no controversy relative to those claims. He did, however, uphold a federal reservation of water from the mainstream fOl' use by the Lake Mead National Recreation Area. But he said that this use is so small-less than 300 acre- feet per year now, with little prospect for increase-that it is not neeessary to set a maximum limit.
