in Klamath and Lower Foe Valleys and the reclamation 

 of Lower Klamath and Tule Lakes, by drainage. The 

 principal source of water supply is Upper Klamath 

 Lake, which has an area of 80,000 acres and is at an 

 elevation of 4,142 feet above sea level. The diversion 

 point for the main canal is at the head of Link River, 

 the outlet of the lake, one mile above the town of Kla- 



the water in Lower Klamath Lake will bo drawn into 

 Klamath River. The canals from Upper Klamath Lake 

 will then be extended over the exposed bed to provide 

 for its irrigation. Tule Lake has its only source of sup- 

 ply in Lost River. This supply is to be cut off from the 

 lake and utilized for the irrigation of the irrigable lands 

 in the valley of Lost River. Tule Lake will then dry

math Falls. Two canals, one on each side of the river, 

 having a total length of fifty miles and a capacity of 

 1,800 feet per second, will cover the irrigable lands. 

 The branch canals will have a length of fifty-two miles, 

 with one hundred and sixty miles of laterals and a 

 capacity of 1,264 second-feet. The plans provide for 

 four crossings, concrete and steel pipe, the inverted 

 siphons having a total length of 12,535 feet. 



The plans for draining Lower Klamath and Tule 

 Lakes are exceedingly simple. The present level of 

 Lower Klamath Lake is preserved by a natural dike or 

 ledge of basalt, which extends across Klamath River near 

 Keno. It is proposed to excavate a canal about nine 

 feet deep through this dike, by means of which most of 



up and later its bed will be irrigated from the canal 

 system of the lower project. 



The estimated cost of the entire project is $4,500,000. 

 Contracts for the first nine miles of the main canal were 

 awarded to a Portland, Oregon, firm, for $377,330, on 

 February 16th, and the work of excavation is already 

 well under way. This canal at the lower end will be 

 forty-five feet wide on the bottom, sixty feet wide on top, 

 and six feet deep. Link River is tapped with a tunnel 

 three-quarters of a mile in length with a cross section 

 of thirteen and a half feet by thirteen and a half feet, 

 and faced with cement its entire length. More than one 

 hundred miles of main canals will be required to supply 

 the whole vallev.
