IRRIGATION AND HYDRO-ELECTRIC DEVELOPMENTS 

 creased as required out of storage, there having 

 been constructed a large storage reservoir at Big 

 Meadows on the North Fork of Feather River. The 

 dam forming this reservoir is an earth dam with 

 concrete core. 



Other Hydro-Electric Developments in Califor- 

 nia. Other notable hydro-electric developments in 

 California are those on the southern streams which 

 supply power to Los Angeles and vicinity, as also 

 in the northern part of the State the Northern 

 Electric Company and the Snow Mountain Power 

 Company. Reference may be made, too, to the 

 power development proposed for the Los Angeles 

 water supply system. On the new city aqueduct, 

 which has a length of 235 miles and a capacity 

 of about 400 cubic feet per second (250,000,000 

 gallons per day) there are several points where 

 the fall in the line is to be utilized for the genera- 

 tion of power. Some 80,000 horse power are to be 

 thus ultimately made available. 



Washington Water Power Company, Washing- 

 ton. In the State of Washington at Spokane, easy 

 of access, is a noteworthy hydro-electric plant. 

 There are three developments in operation and an- 

 other in course of construction. The Spokane River 

 has a minimum or low-water flow of about 1500 

 cubic feet per second. This is considerably in- 

 creased by controlling the outflow from Coeur 

 d'Alene Lake above Spokane, in which Spokane 

 River has its source. The controlling works are 

 located about ten miles below the lake at Post Falls. 

 Here the river separates into three channels, on 

 the southerly of which is the power house. The 

 four turbines installed at this point operate gen- 

 erators which have a combined capacity of 8800 

 kilowatts. At Little Falls, about thirty miles north- 

 west of Spokane, the company has another power 

 station at which the water wheels, also four in 

 number, can develop a maximum of 44,000 horse 

 power. In the same vicinity there is being added 

 to the system the Long Lake development where 

 the water power installation will reach 89,000 horse 

 power. 



The Portland Railway Light & Power Company, 

 Oregon. Electricity for light and power are sup- 

 plied to Portland, Oregon, by the Portland Railway 

 Light & Power Company. This company has five 

 hydro-electric and five steam generating plants. 

 Tnese have a combined capacity of 76,980 kilowatts. 

 The hydro-electric plants have a capacity of 53,230 

 kilowatts, and produce over 90 per cent of the 

 power consumed. The oldest of the hydro-electric
