too. without any lake pondage, with steep sharp slopes, and with 

 everything against high flows. Obviously, then, the conclusion 

 that Schoharie creek flows as high as 0.4 cubic foot per second per 

 square mile is absurd. At present the writer does not feel justi- 

 fied in assigning to it. on the evidence, more than from 0.2 to 0.25 

 cubic foot per second per square mile. Such flows, however, prob- 

 ably do not continue very long, because the stream responds 

 quickly to relatively small rains, which is certainly an advantage, 

 the more especially because the rainfall is possibly slightly greater 

 in the elevated highlands from which this stream issues than it is 

 in less elevated regions. 



It was also stated : 



In the absence of gagings of Schoharie creek the determination 

 of the minimum flow is a matter of judgment, but taking into ac- 

 count all the evidence, the writer believes he has given Schoharie 

 creek a liberal place. 



Since that time definite gagings have been kept, showing that 

 the low-water flow of this stream is lower even than estimated 

 from general considerations in 1900; it is. in fact, shown to be an 

 exceedingly poor water yielder, and it is clear that the writer's 

 report of 1900 did not place the low water flow as low as it 

 really is. 



Minimum flow of East Canada creel:. The mean low-water flow 

 of this stream at Dolgeville for September. 1899, was 92 cubic feet 

 per second. For eleven days it was 67 cubic feet per second 

 ( catchment. 256 square miles) . or at the rate of 0.26 cubic foot per 

 second per square mile. For August, 1899, the mean flow for the 

 month was 97 cubic feet per second. For September. 1900, it was 

 133 cubic feet per second. 



Minimum flow of West Canada creek. The mean flow of this 

 stream at Middleville for September, 1899. was 221 cubic feet per 

 second (catchment, 518 square miles), or at the rate of 0.12 cubic- 

 foot per second per square mile. For several days the flow was 

 only 115 cubic feet per second, and for eleven days, September 

 2-12. inclusive, the mean flow was 183 cubic feet per second, or at 

 the rate of 0.35 cubic foot per second per square mile. In the pre- 

 ceding month of August the mean flow for the month was 235 cubic 

 feet per second. These figures show the superiority of both East 

 and West Canada creeks over Schoharie creek as water yielders.
