This record of Genesee river is made up as- follows : From April, 

 3890, to November, 1892, actual gagings of Oatka creek, above 

 The village of Warsaw, with a catchment area of 27.5 square miles, 

 have been used. From December, 1892, to August, 1893, in- 

 clusive, gagings were not kept of Genesee river, and accordingly 

 for this period the runoff is approximately computed from the 

 rainfall. September, 1893, to February, 1897, inclusive, the 

 record is that of Genesee river at Mount Morris (catchment, 1070 

 square miles). Early in March, 1-697, the dam over which the 

 gagings were made was carried away by a flood and the record 

 for the balance of that year and for the year 1898 is deduced 

 from the record at Kochester (catchment, not including Hemlock 

 lake, water supply of the city of Kochester, 2365 square miles) . 



In 1896 a sharp-crested weir was erected on Genesee river about 

 t wo and one-half miles above the gaging dam, where rock bottom 

 clear across the river afforded an opportunity for such construc- 

 tion without heavy expense. This weir was made perfectly tight.
