ooo second feet. Generating- equipment will be installed to utilize the 

 normal flow of 6.000 second feet in six vertical single runner waterwheel 

 units of 10,000 kilowatts capacity each. To illustrate the high efhciency 

 which can be obtained in a modern waterwheel of this type, it may be 

 stated that manufacturers have promised an efficiency of 90% for these 

 wheels, and this efficiency has even been exceeded by similar wheels which 

 have already been built. The power plant will be built on a rock ledge just 

 below the falls and will take its water through six short steel pipes leading 

 directly to the dam. 



''The Great Falls development will supply power to the territory cov- 

 ered by the present system and to the Chicago. ?ililwaukee & St. Paul rail- 

 way from Harlowton to Deer Lodge. 



It Will Pull "The Thompson Falls development will be similar to the 



the Trains Great Falls development, in that approximatel_v one-half the 

 Over High head exists in the form of a natural fall and the other half 

 Mountains, will be developed by a dam immediately above this fall. In 

 the case of Thompson falls, however, the plant will be situated 

 some little distance below the falls and the water conducted thereto through 

 an old dry channel, which will be flooded when the dam is built. The 

 design of generating units and the general plan of the power house will 

 be similar to that of the Great Falls plant. A total head of about 50 feet 

 will be utilized. The Thompson falls development will supply power to the 

 territory west of that which is covered at present and to the Chicago, 

 Milwaukee & St. Paul railway from Deer Lodge to Avery, Idaho. 



"The addition to these two plants will more than double the present 

 capacity of the system, but it is estimated that this increase will be absorbed 

 within a very short time after the completion of the plants, which will 

 require two or three years." 



^luch of the power developed in this State is now used in the mining 

 and smelting industries at Butte, Anaconda and Great Falls. The mines in 

 Butte use electric power principally for operating compressors, hoisting and 

 pumping. 



The Mines In addition to the plants already built and under construc- 



and Smelt- tion, there are a large number of power sites standing ready 

 ers Use to be developed as demands for power continue to increase. 



Electricity. Although these developments are located in all parts of the 

 State, the larger possibilities exist in the northwestern section 

 of Montana, where the waters of the Flathead, the Kootenai river and other 

 large streams present possibilities for the development of at least 500.000 

 horse-power. The power site at the mouth of Flathead lake, \Vhich is one 

 of the most feasible in the State, has been reserved by the government in 

 connection with the reclamation system centering a portion of what was form- 

 erly the Flathead Indian reservation. A number of smaller power sites have 

 also been reserv-ed, while man}- others are under private ownership. 



-Montana needs strong, self-reliant, stout hearted men.
