Chemung river. This river is formed by the confluence of the 

 Cohocton, Canisteo and Tioga rivers, at Painted Post. The 

 Tioga river receives the Canisteo at Erwin, a few miles south- 

 west of Painted Post. The elevation at .Painted Post is 947 feet 

 above tidewater. From Painted Post the. Chemung river pursues 

 a southeasterly course, crossing the State line at Waverly and 

 joining the Susquehanna near Athens, in Bradford county, Penn- 

 sylvania, a short distance south of the State line. 



Tioga river. This stream rises in Tioga county, Pennsylvania, 

 and flows north to join the Cohocton at Painted Post. 



Canisteo river. This stream is the principal tributary in New 

 York of the Tioga river, joining it five miles south of Painted Post. 

 It rises in the extreme northeastern part of Allegany county and 

 flows southeasterly to its junction with the Tioga at Erwin. 



Cohocton river. The Cohocton river rises in the town of Spring- 

 water in Livingston county and flows southeast to join the Tioga, 

 at Painted Post. There are several small powers on this stream 

 at Bath and other places. The area drained by the Cohocton and 

 Canisteo rivers is almost entirely denuded of forests, and these 

 streams are in consequence less valuable for water power than 

 formerly. For a considerable length of time in the fall of 1895 

 the natural yield of these streams was probably not more than 

 0.05 of a cubic foot per second per square mile. At an early date 

 the Cohocton, Canisteo and Tioga rivers were extensively utilized 

 for floating logs to market, but this business has, of course, long 

 since ceased for lack of material. 



The topography of the country from which these streams issue 

 may all be classed as semi-mountainous. The parts remote from 

 the main streams are roughly rolling, while in their vicinity the 

 topography is more rugged, with valleys flanked by high and steep 

 hills, in many cases precipitous and bluff-like at their bases. The 

 main valleys are at elevations ranging from 800 to 1200 feet above 

 tidewater, while the hills rise to an altitude of 2500 feet. 



Cayuta creek. This creek rises in the central part of Chemung 

 county and flows south through Waverly into the Susquehanna 

 l iver just south of the Pennsylvania line. Its headwaters are at
