haTf a mile to one mile wide and witli an average depth of sixty 

 feet. As shown by tables Nos. 84 and 85. it would control the 

 entire flow of the river above Portageville, where the catchment 

 area is 1000 square miles. Detailed statements as to the rainfall 

 and water yield of Genesee river catchment may be found in the 

 writer's report on Genesee river storage in the Report of the 

 State Engineer and Surveyor for 1896, as well as in the preced- 

 ing pages. 



Genesee river tcaterpower. The water-power of Genesee river 

 is nearly all concentrated in six heavy falls. Three of these are 

 within the limits of the city of Rochester and three are at Portage. 

 The total descent from the head of the falls at Portage to the 

 level of Lake Ontario is 833 feet, of which 262 feet are at 

 Rochester and 290 feet at Portage. At Mount Morris the fall is 

 18 feet; between Mount Morris and the foot of the lower falls 

 at Portage, 210 feet; the balance is in a reach of meandering river 

 between Rochester and Mount Morris where, aside from small 

 powers at Geneseo and York, there are no opportunities for 

 developing power. 



The present developed power on the stream is at Rochester,. 

 Geneseo, York and Mount Morris; the Genesee canyon and Port- 

 age falls are virgin territory, with no power now developed on 

 this reach of the stream. With this storage project carried out, 

 nearly 26,000 gross horsepower may be developed here. 



The figures on page 590 show a total of 57,223 gross horse- 

 power on Genesee river from Portage to Rochester. It is believed, 

 however, that the computations for storage have been so con- 

 servatively made that it will yield fully 60,000 gross horsepower 

 in the year of lowest flow. The tabulation on page 590 also show& 

 a total at Rochester of 29,840 gross horsepower to be derived from 

 1000 cubic feet per second flow. This total is based on a utiliza- 

 tion of the entire fall of 262 feet. Probably this is impracticable 

 and 28,620 gross horsepower may be taken as the safe figure for 

 a flow of 1000 cubic feet per second. However, the computations 

 of tables Nos. 84 and 85 have been made on the basis of 80 cubic 

 feet per second to the Erie canal, but under the new conditions 

 existing in 1904, with the barge canal authorized and the entire 

 water supply to be taken from Lake Erie, we may consider the
