TWO IRRIGATION PROJECTS. 



I, The San Carlos Dam, 



IN the recent annual report of the 

 Secretary of the Interior he recom- 

 mended the construction of three pro- 

 jects, the lir.st of these being the San 

 Carlos dam, on Gila River, in southern 

 Arizona. The picture given here is a 

 .sketch of the propo.sed dam, showing 

 the lake created and the flood water 

 pouring out through the waste ways on 

 each side. 



This project is designed to regulate 

 the flow of Gila River, .storing the floods 

 for the use of the agricultural Indians 

 on the reser\'ation below,. and also to 

 furnish water to at least 100,000 acres 

 of government land in the valley be- 

 tween Florence and Casa Grande, a 

 station on the Southern Pacific Railroad. 

 The lands to be irrigated have been re- 

 served from entry and settlement by the 

 Secretary- of the Interior. 



The cost of the dam is estimated at a 

 little over $1,000,000. Measurements 

 of the flow of the river at this point 

 show that there is ample water to fill 

 the reser\'oir, and that in addition to 

 the needs of the Indians at lea.st 100,000 

 acres can be irrigated. The reser\'oir 

 site is on the Apache Indian Reserva- 

 tion, below Solomonsville \^alley. The 

 ground to be flooded has little value, 

 small patches being utilized by the In- 

 dians. These farms can be transferred 

 to higher land along the resen-oir, which 

 will be wet in part by the receding 

 waters of the lake and by ditches head- 

 ing above the upper end of the reser\'oir. 



Water for irrigation will be drawn 

 out through the bottom of the dam, 

 being controlled by gates located at the 

 foot of the towers shown in the picture ; 

 a portion also can be taken out by a 

 tunnel run through the solid rock of the 

 abutments. By so doing a considerable 

 part of the silt deposited in the reser- 

 voir will be drawn off, and the remainder, 

 if it tends to accumulate, can be dredged 

 or .sluiced out by hydraulic processes, 

 keeping the re.ser\'oir clean. 



The water discharged back into the 

 stream follows a narrow, rocky canyon 

 for about forty miles. Measurements 

 show that losses in this canyon from 

 evaporation are compensated b)^ the 

 seepage received from side canyons. 

 Passing beyond the Buttes, twelve 

 miles above the town of Florence, the 

 waters will be recovered in a canal 

 located above all existing ditches, a 

 sufficient amount being allowed to flow 

 down to supply the needs of prior ap- 

 propriators. 



This large canal will be continued out 

 on the south .side of the river above ex- 

 isting works, a branch conducting water 

 down to the Indian lands and another 

 covering the public lands. 



The legislation before Congress con- 

 templates throwing open this land to 

 homestead entry in small tracts, pay- 

 ment to be made to the government for 

 the cost of storing the water, the annual 

 installments being small. Title to the 

 land will be given only after the propor- 

 tional cost lias been refunded by the 

 settler.
