 lfIiBdllOIl NdlGI ldS Detll pAt-lililul The beds of the various streams con- tain decreased volumes of water. Tn the northern counties the stream beds are still covered by depths of water ranging from 1 foot to feet Tn the Salt. Gfla. Santa Cruz. San Francisco and San Pedro river beds, the depths of flowing water range from 1 foot to feet. The areas embraced within the canal zones of the Territory are full of flowing water. Irrigation ser vice was maintained, uninterruptedly, during the entire week The volume of flow in the various canals was fully up to standard of measurements of the preceding week In the lower Salt and lower Gila, the water appears to be very thick and muddy. indicating that the run-off. produced by the recent copiOus rainfall has not entirely passed gulfward.
