142 IRRIGATION INVESTIGATIONS IN CALIFORNIA. 



of sale is 18 cents a day per horsepower. The charge for water sold in bulk to 

 municipalities is 18 cents and upward per inch, according to amount, cost of 

 delivery, etc. Where waterworks are owned by the company the rates are collected 

 from families on a gross charge for general family use, under liberal regulation 

 charges. These average $2 per month per family. 



Value of the Property. 



Including the water rights and rights of way the entire property owned by the 

 South Yuba Water Company is now valued at $4,000,000. 



SUMMIT WATER AND IRRIGATION COMPANY. 



The propertj' of this company is situated on the ridge between the South and 

 Middle forks of Yuba River. Its water rights represent the combined rights of 

 several companies and are among the oldest in the Yuba River Basin. The works 

 were constructed between 1851 and 1856. They were originally constructed to furnish 

 water to the various miners along the ridge, but recently the company has acquired 

 mining properties and the water is nearly all used upon these properties. 



From Eureka to the summit of the Sierras the geological formation is principally 

 granite. The slopes rise into high and rugged peaks, some of which attain an 

 elevation of 8,500 feet. The Middle and South forks with their tributary streams, 

 such as Canyon Creek, Pass Creek, and others, rise in these mountains, among which 

 are numerous lakes from 20 to 400 acres in area. The Summit Water and Irrigation 

 Company has formed a sj^stem of reservoirs bj^ building dams at the outlets of many 

 of these lakes. 



Eureka or French Lake is situated at the head of Canyon Creek about 4 miles 

 west of the summit, and is the principal reservoir of this system. A substantial dam 

 formed of granite blocks was erected in 1858 and 1859, at a cost of $35,000. The 

 width at bottom is 120 feet, height 70 feet, and length on top 250 feet. The front 

 is protected with two layers of 25-inch lumber well secured to the face of the 

 dam. An arched sluice is constructed through the dam, bj^ which the flow of water 

 is regulated. The high-water mark is 62.5 feet above the bottom of the outlet. The 

 area is 337.2 acres and the capacity 661,000,000 cubic feci. Mr. George Black 

 I'eported in 1864 that the height of the Eureka Dam could be safely raised 12 feet, or 

 to a total height of 82 feet. This would increase the storage capacity of the dam 

 262,000,000 cubic feet. The catchment area of the lake is 5 square miles. 



The waters of Eureka Lake flow down Canj'on Creek 10 or 12 miles to Faucherie 

 Lake, which is about 600 feet lower in elevation. Faucherie Lake is the basin of a 

 natural lake, the surface of which was originally raised by a dam 44 feet high, forming 

 a reservoir with an area of 139 acres, a catchment of 3,262 acres, and a capacity of 

 170,000,000 cubic feet. This dam was washed away and has been replaced by one 21 

 feet high, which forms a reservoir with an area of 90 acres, a capacity of 50,900,000 

 ciiVjic feet, or about one-third the capacity of the reservoir as first constructed. 

 The cost of this new dam was $8,000. 



Weaver Lake is a natural lake situated about 2 miles north of Bowmans. Its
