fruits, do well, especially on the higher portions of the project near 

 the bliiifs, and potatoes can be raised on the south side of the river, 

 where the soil is more sandy. The main crop, however, is alfalfa 

 and native hay for use as winter feed, the great number of cattle and 

 sheep summer pastured on the open range surrounding the project 

 creating a demand for alfalfa. The fruits and vegetables raised on 

 the project are sold to the mining camps in the Black Hills. 



Utah, Strawheri'nj Valley jwoject. — This provides for the irrigation 

 of about 60,000 acres of land in Utah and Wasatch Counties, on the 

 eastern shore of Utah Lake. The water* supply will be obtained 

 from a storage reservoir to be built in Strawberry Valley, about 30 

 miles east of the irrigable area. By means of a tunnel (pi. 11, fig. 1) 

 about 3| miles (19,200 feet) long the stored waters will be carried 

 through the mountains and emptied into Spanish Fork, from which 

 a canal 18 to 20 miles long will convey them to the irrigable area. 

 Power created from the high-line canal is now transmitted electrically 

 to the tunnel for drilling, and later will be utilized to pump water to 

 lands above the gravity system and for drainage of low-lying lands. 



The lands have an elevation of about 4,600 feet, and the tempera- 

 ture ranges from —10° to 95°. Alfalfa, hay, cereals, sugar beets, 

 fiiiits, and vegetables are grown. Settlers are getting ready to plant 

 orchards as soon as water is available. The existing canals are being 

 enlarged to form part of the Government system. 



The watershed area is 870 square miles, the annual rainfall on 

 watershed 45 inches, and the estimated annual run-off 168,000 acre- 

 feet. 



Washington, Okanogan project. — The most interesting engineering 

 feature is a storage dam 64 feet high and 1,000 feet long, built by the 

 hydraulic fill process, forming a reservoir with a capacity of 13,000 

 acre-feet. The watershed area is 150 square miles, the average an- 

 nual rainfall on watershed 17 inches, and the estimated annual run- 

 off 37,000 acre-feet. The annual rainfall on the irrigable area is 

 8 inches. \ 



This project is designed to supply water to 10,000 acres of land in 

 Okanogan County, Wash. The soil is decomposed basalt, sand, and 

 gravel, and is very fertile. Grain, hay, fruit, nuts, and vegetables 

 are grown, but the principal crop is apples. The elevation of the 

 land is about 1,000 feet above sea level. The temperature ranges 

 from —10° to 105°. In the history of 20 years of fruit growing in 

 the valley frost has not seriously injured the crops, and there has 

 never been a failure with apples, peaches, plums, prunes, apricots, 

 pears, cherries, nectarines, grapes, or any variety of small berries 

 grown there. 



On account of the possibilities of high development in this section 

 the farm unit has been fixed at 40 acres. The building: charge is
