"Power from this plant is transmitted at 6,600 volts to the smelter at 

 Great Falls over duplicate steel tower transmission lines operating at 100,000 

 volts. From Butte an additional line is extended to Anaconda so that at 

 present almost the entire capacity of both the Rainbow plant and the 

 Missouri river plants are utilized in the mines of Butte and the smelters at 

 Anaconda and Great Falls. In addition to these main transmission lines 

 additional feeders of smaller capacity have been built from the Rainbow 

 plant to Lewistown, Havre and Cascade. 



"In 1906 and 1907 a timber dam Avas built on the ^lissoula river, six 

 miles above Missoula, just below the mouth of the Blackfoot river. A
