Floods in Wallkill river. Very little information is available 

 as to the flood-flows of this stream any further than that on August 

 7. 1901, the discharge at New Taltz was 7365 cubic feet per second 

 i catchment. 730 square miles) . or at the rate of 10 cubic feet per 

 second per square mile. The extreme flood must be much higher 

 than this. Mr Vermeule states that high-water marks on Clove 

 river, one of the tributaries of the Wallkill river, indicate a maxi- 

 mum discharge of 07 cubic feet per second (catchment, 0.7 square 

 mile), or at the rate of 96 cubic feet per second per square mile. 1 

 This catchment is perhaps rather small for final conclusions. 



Floods in Esopus creel:. According to the statement of M. E. 

 Evans in a report to the Saugerties Manufacturing Company, the 

 maximum flood in Esopus creek at Saugerties occurred on Decem- 

 ber 10, 1S7S. This flood resulted from a snowfall of six inches, 

 followed by excessive and continuous rain for three days. The 

 extreme depth on the crest of a dam 330 feet in length was 14 

 to 14.5, feet, indicating a flood discharge of from 50.000 to 60,000 

 cubic feet per second (catchment, 417 square miles), or at the 

 rate of from 120 to 145 cubic feet per second per square mile. 



Floods m Rondont creel:. The most severe flood in this stream 

 was that of March 1. 1902, when there was a discharge as meas- 

 ured at Rosendale of about 14.000 cubic feet per second (catch- 

 ment, 365 square miles), or the flow was at the rate of 38 cubic 

 feet per second per square mile. 



Floods in Cat si: ill creel:. This stream is of rapid descent and 

 subject to wide variation in flow. From high-water marks at 

 Woodstock dam the flood-flow in the spring of 1901 has been com- 

 puted at 21.000 cubic feet per second (catchment. 210 square 

 miles) , or at the rate of 100 cubic feet per second per square mile. 



Floods in the Normans kill. So far as can be learned, the only 

 information in regard to flood-flows of this stream is given in a re- 

 port of the Water Commissioners of Albany to the Common Coun- 

 cil in 1891 ns to the advisability of ut ilizing this stream for a water 

 supply for the city of Albany. Tn this report the catchment area 

 above French Mills is stated at 111 square miles. From 

 measurements taken in February, 1*91. the flow was 1240 cubic
