Quebec to 740 square miles. The total area of the catchment, not 

 including water surface, is 7960 square miles, or the total area of 

 the catchment basin, including water surface, is 8360 square miles. 

 Lake Champlain is considered as beginning at Whitehall and ter- 

 minating at St Johns, on the Richelieu. Its length is 125 miles 

 and its breadth in the northern portion is about 13 miles. The 

 standard low-water elevation is given at 95.03 feet, and the 

 standard high water at 103.78 feet, above tide. 



The streams tributary to Lake Champlain are Big Chazy, Little 

 Chazy, Saranac, Salmon river east, Little Ausable, Big Ausable, 

 and Bouquet rivers and the outlet of Lake George. There are also 

 a few small streams of no special importance. 



Big Chazy river. This stream rises in the western part of 

 Clinton county, and flows in an easterly direction into Lake 

 Champlain, at King bay, five miles south of the village of Rouse 

 Point. The main branch issues from Chazy lake, of which the 

 elevation is 1500 feet above tidewater. The headwaters of the 

 north branch probably are at a somewhat greater elevation than 

 this. The catchment area is 300 square miles. 



Little Chazy river. This river enters Lake Champlain two 

 miles south of the Big Chazy. 



Saranac river. The streams tributary to Lake Champlain are, 

 as a rule, not of great length, but rising, as they nearly all do, in 

 or near the high mountains of the northern plateau, they have 

 a rapid descent with an abundant fall. Saranac river has its 

 head chiefly in Upper Saranac lake, 1 at an elevation of 1577 feet 

 above tide and flows northeasterly, entering Lake Champlain at 

 the village of Plattsburg. The length of the river, according to 

 Bien's atlas, is 55 miles from its mouth to Lower Saranac lake. 

 The elevation of Lake Champlain above tidewater is 101 feet, 

 while that of Lower Saranac lake is 1539 feet; hence, the fall in 

 55 miles of river course is 1438 feet. Middle Saranac lake lies 

 at an elevation of 1542 feet and Upper Saranac, as already given, 

 at 1577 feet. 



l There are a number of lakes and ponds tributary to Upper Saranac lake 

 which are not here specially considered.
