18 COMMERCIAL IMPORTANCE OF WHITE MOUNTAIN FORESTS. 



basin includes about 11,000 square miles (10,924), of which about 

 2,500, or nearly one-fourth, lie in New Hampshire. About 2,000 

 square miles of its catchment basin are in the White Mountain region 

 of New Hampshire, and its tributaries in this area are shown in the 

 following tabulation:

The sources of these tributaries of the Connecticut are found at 

 high altitudes. The third Connecticut Lake, which is the source of 

 the main river, is 2,038 feet above the sea. Thence, over thirteen 

 or more dams which store the water for log driving or make it avail- 

 able for local mills, it falls 1,600 feet in 113 miles, and 430 feet in the 

 remaining 262 miles. In its upper reaches it is a turbulent stream, 

 with tributaries (Halls, Perry, and Indian streams) of the same 

 character. 



The eastern edge of the watershed through the White Mountain 

 region averages about 4,000 feet elevation and includes the great 

 mountains of the Presidential and Franconia ranges from Mount 

 Madison to Mount Moosilauk, many of them above 5,000 feet. The 

 steep and rocky slopes, without large lakes or swamp areas, cause an 

 uneven flow, restrained solely by the moisture-holding power of the 

 forest. The upper water powers are developed chiefly at Fifteen 

 Mile and Mclndoes Falls on the main river, and at Littleton and 

 Lisbon on the Lower Ammonusuc, but the region has many local 

 mills of small individual output, yet with a total product of 

 considerable value. Mclndoes Falls, which mark the lower end of 

 the turbulent part of the Connecticut, 7 miles above Wells River, 

 has a fall, of 12 feet, and more than 1,000 available horsepower, of 

 which 400 has been utilized for many years by a large sawmill. At 

 Littleton various wares and lumber are manufactured, and at Lisbon 

 chiefly lumber. One company at Lisbon manufactures piano sound- 

 ing boards from spruce butts, a product that in its final form is 

 widely distributed throughout the United States.

& There are several other small streams, the Mohawk for instance, with drainage 

 areas of about 20 square miles.
