developed powers on the Ausable. The merchantable timber has 

 mostly been cut, and the original dams used by the lumbermen for 

 floating logs have decayed. There is a large undeveloped water 

 power at Wilmington notch, where there is a fall of 100 feet. 

 There is also a fall of 100 feet at High Falls. From the upper end 

 of Wilmington notch to two miles above the village of Wilmington 

 there is a fall of 600 feet in a distance of four miles. This part 

 of the stream is as yet entirely undeveloped. These water powers 

 are on the west branch of the Ausable which heads in Lake Placid. 



Bouquet river. The Bouquet river rises in the eastern part of 

 Essex county and flows northerly to the village of Willsboro and 

 thence southeasterly for two miles, when it enters Lake Cham- 

 plain. 



Outlet of Lake George. The most southerly tributary of Lake 

 Champlain of any great importance for water purposes is the 

 outlet of Lake George, which in about 2 miles has a fall of 222 

 feet. The greater portion of this is concentrated in the first mile 

 from the lake. The elevation of Lake George above tidewater is 

 323 feet. The area of the lake surface is 13 square miles, and the 

 tributary catchment area about the foot of the lake is 229 square 

 miles. 



The streams in eastern XeAv York can not be depended on to 

 furnish a natural flow of more than about 0.2 cubic foot per sec- 

 ond per square mile as a minimum in a dry year. On account of 

 the large water surface of Lake George in proportion to the catch- 

 ment area, it is possible, by utilizing the storage on the lake sur- 

 face, to realize in an average year a much larger quantity. From 

 0.7 to 0.8 cubic foot per second per square mile may be assumed as 

 a conservative estimate, the results being based on allowing the 

 water to flow out of the lake 21 hours per day for only 310 days in 

 i ho year. On this basis we may assume a mean flow for minimum 

 dry years of about 200 cubic feet per second. Since the entire 

 222-foot fall of the Lake George outlet is now utilized, we may 

 I lace the permanent power in a dry year at about 5000 gross
