be the largest artificially formed lake in the world. It forms a body

of water 25 miles long, almost 2 miles broad, and with a maximum depth

of 220 feet. The main canals are 119 miles in length and the lateral

canals 208 miles. Not only will this structure insure a supply of water

in the Salt River valley where, in recent years, orchards and other

products have perished, but it will prevent the floods which have

devastated that region from time to time. Water-power amounting to

25,000 horse-power has been developed by the construction. This power

is used in part for pumping, and another area, estimated at 40,000

acres, outside the territory covered by the canals has been reclaimed.
