 The rapid melting of snow in the drainage areas of the Colorado, the Eittle Colorado, the Salt and Gila riv- CTS is producing a good run-off, where by moderate flows Of water are being maintained. Tn the upper section of the Salt river watershed. the snow at the higher levels of the mountains varies in depth from twelve inches to forty inches: in the Little ColoTado' river watershed. fourteen inches to forty inches; in the Giia river water shed eight inches 10 thirty-six inches. There is considerably less snowfall in the mountains than there was dur ing the corresponding period of 1906. The riyerbeds, likewise, contain less volumes of water. The present quan- tity of snow in the mountains assures an adequate supply of water. which will last until June next The water holes upon the desert ranges contain good supplies The intakes at the head of the canal zones contain large volumes of water. Service throughout the main canal systems. leading to the smaller crosscut and lateral canals, continued uninterrupted.
