462 SEVENTH REPORT OF THE FOREST, FISH AND GAME COMMISSION. 



John B. Jervis, in 1835, of Madison and Eaton brooks, the State of New York had 

 never made any gagings, a fact which can hardly be placed to the credit of the 

 authorities of this State. Measurements of Croton River had, however, been made 

 by the City of New York since about 1868. Oatka Creek, a tributary of Genesee 

 River, with a catchment area of 27.5 square miles above the point of measurement, 

 was gaged by the present writer from April. 1890, to November, 1892. In 1895 a 

 survey of the Upper Hudson River was authorized, of which the writer was placed 

 in charge. It so happened that his previous experience had been extensively along 

 the line of gaging streams, and he accordingly very early devoted considerable 

 attention to this matter. Inquiry soon developed the fact that The Duncan Com- 

 pany, at Mechanicville, had kept gagings of the flow of Hudson River since 

 October, 1887. This matter was immediately examined into, new gages set, and 

 additional refinement introduced in the work, which has been continued to the 

 present time, \\ith the result that the gagings of the Hudson River form one of the 

 best long time series of a large river thus far made in the United States. The 

 catchment area at Mechanicville is 4,500 square miles. 



The catchment area of Hudson River is. as per final determination for the 

 Board of Engineers on Deep Waterways, 4,507 square miles.* This, however, is so 

 slight a difference as to render it inadvisable to be taken into account, since the 

 error is only about 0.15 of one per cent. 



Gages were also established at Fort Edward on the Hudson River, and at War- 

 rensburg on Schroon River. At the time of establishing the gagings at Warrcns-
