THE IRRIGATION AGE. 



of about 240,000 acres of fertile valley and lake bottom 

 lands in the Klamath Basin in Oregon and California. 

 It stands out unique among the several stupendous 

 works proposed by the Reclamation Service, and involves 

 features of irrigation, storage and drainage in unusual 

 combination. About fifty-five per cent of the total irri- 

 gable area is United States public land, and about sixty-

 sixty miles,' finally emptying into Tule Lake, which is 

 only six miles distant from the source of the river. 

 Storage for the Upper project is provided in Clear Lake 

 reservoir by constructing a dam across Lost River two 

 miles below its junction with Willow Creek. The capac- 

 ity will be 462,356 acre-feet. An auxiliary reservoir,

two per cent is located in Oregon. The topographic 

 features as shown on the map are singularly interesting. 

 Nature has kindly placed the water and the land in such 

 nice juxtaposition that the engineering works required 

 are comparatively simple, and the average cost for irriga- 

 tion per acre is the lowest of any of the projects so far 

 approved by the government. 



The Klamath project is naturally divided into two 

 distinct parts the Upper and the Lower projects each 

 having a separate source of water supply. The Upper 

 project provides for the irrigation of about 50,000 acres 

 in Langells, Yonna, Poe and Upper Klamath Valleys. 

 These valleys are drained by Lost Eiver, which rises in 



known as the Horsefly, with a capacity of 125,000 acre- 

 feet, will be formed by constructing a dam across Miller 

 Creek. The Clear Lake dam will be thirty feet high, 

 twenty feet wide on top, and eight hundred and fifty 

 feet long. The Horsefly dam will be seventy feet high, 

 twenty feet wide on top, and four hundred and eighty 

 feet long. Both dams will be constructed of earth and 

 rock. The total length of the main canals of the Upper 

 project will be seventy miles. There will be three cross- 

 ings by inverted siphons, two over Lost River, one over 

 Miller Creek, with total length of 3,212 feet. The 

 estimated cost of the Upper project is $947,776. 



The Lower project involves the irrigation of lands
