154 IRRIGATION INVESTIGATIONS IN CALIFORNIA. 



power, which are used to operate pumps, hoists, and other mining macnmery. This 

 plant is of great importance to this region because of the high price of fuel, which 

 caused the shutting down of many mines. The company delivers a current for power 

 at an average price of |5 per month per horsepower for constant loads. 



The same compan}' has a station near Drj^ Creek, 20 miles northeast of Marys- 

 vuie. The water is taken from, the flume at Colegate and conveyed through 25 miles 

 of ditch to the forebaj', then to the power house through 850 feet of 30-inch riveted 

 sheet-steel pipe, afiording an eflective head of 296 feet. 



The power is transmitted by pole line to Marysville, a distance of 20 miles, and 

 used for lighting the cit}' and general jjower purposes. There is also an 8-mile 

 circuit, delivering lights and power for mining purposes at Browns Valley-, both 

 power and light being taken from each circuit. They also send power to the power 

 house of the Nevada division when that power house is unable to carry its load. 



College Station is also owned by the Ba\- Counties Power Companj-, and is situ- 

 ated on the main Yuba River at a point about 4 miles above the junction with the 

 South Fork. Construction was commenced in May. 1899, and is still being continued. 

 The companj' holds the Page lease of the mechanical privileges of the M'ater of 

 Browns Valley district, and claims an additional right to 10,000 inches in the North 

 Yuba at the headgates. 



The clam in the North Yuba has been raised to a height of 37 feet, and a new 

 flume, 6 by 7 feet, on a grade of 13 feet to the mile, with an estimated capacity of 

 300 cubic feet per second, has been built from the dam to Colegate, a distance of 7.6 

 miles. From the foi-ebay to the power house there is a drop of 695 feet, which is 

 used to develop power. The water is to be conveyed to the wheels in five 30-inch 

 pipes, two of which are now laid. They have a length of 1,600 feet, the first 700 

 feet being riveted steel, and the lower 900 feet cast iron. 



The companj' intends to deliver power at San Francisco and intennediate points, 

 a total distance' of 140 miles. The total cost of the plant will be $3,000,000, 

 $2,300,000 having already been expended. 



At Dobbins a reservoir is being built to be dmwn on in case the water in the 

 flume has to be shut off. Its capacity will be about 35,000,000 cubic feet. Dobbins 

 Creek will be able to fill it during the rainy season. If it becomes necessary to refill 

 it in the summer, part of the water which runs to waste during the period of minimum 

 load is to be used to lift the balance up to the lake. When the reservoir is drawn 

 on the water will be used twice — once to generate power at the forebaj' under a 

 head of 330 feet, and again at the power house under the 665-foot head.
