In 1894 the rainfall dropped to a total of 30.51 inches and the 

 runoff to a total of 8.70 inches, of which 7.63 inches occurred in 

 the storage period. In 1895 the total rainfall was 29.84 inches 

 and the total runoff 4.90 inches, of which 4.04 inches occurred 

 during the storage period. 



Runoff of Genesee river. Genesee river, while not tributary to 

 the Great Lakes above Niagara river, may still be cited as showing 

 that at times the runoff of streams tributary to the Great Lakes is 

 very low. Referring to table No. 43, which, for the years 1890, 

 1891 and 1892, gives the rainfall and runoff of Oatka creek, a 

 tributary of the Genesee, we learn that in the water year 1891, 

 with a rainfall of 38.12 inches, the runoff was 14.05 inches. In 

 1892, with a rainfall of 41.69 inches, the runoff was 15.42 inches.

Taking the record of Genesee river proper, for the years 1893- 

 1898, inclusive, as given in table No. 43, we learn that for the 

 water year 1894, with a mean precipitation above the point of 

 measurement of 47.79 inches, the runoff was 19.38 inches, of which 

 15.73 inches occurred in the storage period. In 1S95 the rainfall 

 dropped to 31 inches and the total runoff to 6.67 inches. In 18S0 

 Hemlock lake, a tributary of Genesee river, with a catchment area 

 of 43 square miles and a total rainfall of 21.99 inches, gave a 

 runoff of only about 3.4 inches.
