THE IRRIGATION AGE. 



LAKE TAHOE ON THE TRUCKEE-CARSON 

 IRRIGATION PROJECT 



Here is the marvelous record of the Truckee- 

 Carson project for 1915, as prepared by the officials 

 of the Reclamation Service : 



Number of people on the farms, 1,986; number 

 engaged in agricultural work, 779; acreage pre- 

 viously cleared and leveled, 30,975 ; additional acre- 

 age prepared in 1915, 1,965; total invested in land 

 and all improvements, $2,992,822 ; present value of 

 farms, with improvements, including livestock and 

 equipment, $3,831,905. 



During the thirteen years that have elapsed 

 since the project was started, more than $6,000,000 



Concrete dam for diverting water from Truckee 

 river into Truckee canal. 



Carson diversion dam, six miles below Lahon- 

 tan dam, and headworks of Northside and Southside 

 canal systems. 



One hundred and four miles of main canals 

 with numerous concrete structures. 



Four hundred and twenty miles of laterals with 

 concrete and wooden structures. 



One hundred and seventy-eight miles of sur- 

 face drains. 



Four miles of tile drains. 



World famous Lake Tahoe, beauty spot of the Sierras. Great natural reservoir, source of Truckee River, furnishing water 

 for power and irrigation near Reno and on Truckee-Carson project. 



have been expended in constructing an efficient, 

 modern, and permanent irrigation system. The 

 system is about two-thirds completed, and the fea- 

 tures already finished and in operation comprise 

 the following: 



Concrete dam for controlling outflow from 

 Lake Tahoe. 



Lahontan dam and reservoir for storage of 

 290,000 acre-feet of water, on the Carson river 

 eighteen miles above Fallon. 



Truckee canal, thirty-one miles long, extending 

 from Truckee river near Derby, Nevada, to the 

 Lahontan reservoir. 



Hydro-electric plant in concrete power house 

 below Lahontan dam, capacity 2,400 horsepower. 



One hundred and twent^eight miles of tele- 

 phone line. y-yF' 



Plans for completion of the project involve the 

 construction of additional storage reservoirs on 

 both the Truckee and Carson rivers, and extensions 

 of the present canal, lateral, and drainage systems 

 for additional units. The first feature undertaken 

 was the Truckee canal, extending from the Truckee 

 river above Derby, 31 miles across the low divide 

 into the valley of the Carson and emptying into the 

 reservoir just above the Lahontan dam. Construc- 

 tion work was started in 1903.
