in this region, the run-off from each square mile, if it is all con- 

 served, will supply 10,000 people. The yield of this drainage 

 basin will probably be sufficient to supply from 150,000 to 200,000 

 people if it is all conserved, as may be very readily done by the 

 Linden reservoir. 



The dam site is just above the bridge at Linden. It is par- 

 ticularly favorable. The foundations will be in solid rock. The 

 length is short, and the sides of the canyon steep. The crest of 

 the spillway will be at an elevation of 1,151 feet above sea level, 

 and about 80 feet above the bed of the stream at the site. About 

 10,000,000,000 gallons of water will be impounded and 1,150 

 acres of land flooded. 



From the reservoir, the water will be taken to a filter plant 

 below, and be filtered, though the supply would be perfectly sani- 

 tary without the filtration. Filtration in this case is simply an 

 insurance measure, so far as healthfulness is concerned. Filtra- 

 tion will, however, improve the appearance and taste of the water. 



Quality of Proposed Service. 



The proposed supply will be free from deleterious bacteria, clear 

 and fairly soft. The head available is not only ample, but will 

 have to be reduced before introduction into the systems of the 

 municipalities to be served. The reduction in insurance rates in 

 towns now served with supplies insufficient in quantity or pressure 

 will aid materially to pay for the new service. 



Capital and Operating Costs of Orleans Project. 



The preliminary estimate for the entire cost of the project is 

 $5,000,000 for the reservoir dam, spillway, regulating works, 

 filters, clear water reservoir, land damages, highway relocation 

 and entire piping system, figured to supply to the municipally 

 owned standpipes a total of 19,000,000 gallons daily. 



Based on state or county or water district bonds, this project 

 could be financed on about a 4% basis. The cost of operation and 

 repairs is estimated at $25,000' per year. The total yearly charges 

 become :
