point in question is near the mouth of the tributary, Allen's 

 creek, and the catchment area above the same is large enough to 

 justify the assumption of a minimum flow of 2,000,000 gallons per 

 day. The lift to Mount Hope reservoir, including friction head 

 in a 16-inch force main, would be at least 300 feet. Filtration of 

 the water would be required, and the total cost of the works on 

 this plan may be placed at f 100,000. 



Allen's creek was the only available tributary to Irondequoit 

 creek, and may be reached at a distance of two miles from Mount 

 Hope reservoir. At this point, however, the minimum flow was 

 probably much less than the desired quantity, so that storage 

 works would have become necessary. The water was, moreover, 

 liable to contamination from the sewage of the county buildings. 



Red creek. This stream rises in the southeastern part of Hen- 

 rietta, and after flowing northwesterly, enters Genesee river a 

 little over one and one-half miles southerly from Mount Hope 

 reservoir. Its catchment area was too small to insure the re- 

 quired daily volume in periods of drought, and its waters were 

 often highly discolored by swamp drainage — in consequence of 

 which it is named Red creek. 



Little Black creek. This stream rises near the middle of the 

 town of Ogden, and after a short southerly course flows through 

 the southern parts of Ogden and Gates to Coldwater station and 

 thence to Genesee river. Its mouth is about three and one-half 

 miles southwest from Mount Hope reservoir, and the water in 

 the river is here about 127 feet below said reservoir. All of the 

 springs in the vicinity of Coldwater, as well as Snow springs 

 farther west, discharge into this creek after flowing through ex- 

 tensive swamps. Casual examination of the stream near Cold- 

 water showed not only that the water could not safely be used 

 for drinking purposes without filtration, but also that its flow 

 was not more than 1,500,000 or 2,000,000 gallons per day. Under 

 these circumstances this source could not be recommended, as it 

 was certain that the flow would diminish greatly during a dry 

 season. 



Wells at Coldwater. It was rumored that a large supply of 

 excellent water could easily be obtained from wells at Coldwalor.
