Adirondack Beaver 137 



On the west shore of Lake Eaton were found the largest beaver- 

 cut aspens encountered; the largest measured 17.5 inches in diameter 

 at the lower end of the cut, the others 12.5 inches, 16 inches, 16.25 

 inches, respectively (figure 18). 



6. Forked Lake Region. At the eastern end of this lake a stream 

 from the north enters the North Bay. A swath of dead timber 

 killed by beaver flows some years ago extends upstream for about 

 half a mile. From there on, beaver operations in progress at the 

 present time have caused some further damage. Approximately a 

 mile from the mouth of the creek occurs the largest recent flow met 

 with on this stream, where about four or five acres of spruce trees 

 from 6 to 10 inches in diameter are standing in water and have begun 

 to turn yellow. This is a locality of low ground which is easily 

 flooded. 



I was informed by Ranger Robinson about a large beaver flow 

 on the Whitney Preserve, along Sperry Brook below Handsome 

 Pond. Mr. Robinson's plans for taking me to this locality were 

 unfortunately thwarted by the occurrence of fires in his district which 

 required his close attention. This flow west of Long Lake, is by 

 far the largest in that general region, according to Mr. Robinson. 



7. Blue Mountain Lake Region. The most extensive beaver flow 

 in this ranger district occurs on the Salmon Lake stream. About 

 half way between Salmon Lake, and the road to the west of it 

 there is a dam across this stream which is 75 feet long and 3 

 feet high (figure 19). A flow containing a belt of dead timber 

 perhaps 12 rods wide extends upstream for a distance of approxi- 

 mately one mile. Near the road is another large dam which has 

 been abandoned. The dead timber in the long flow consists of 

 rather small or medium-sized spruce and balsam fir mixed with 

 birch (figure 20). 



On the neighboring Mud Pond inlet stream, where it parallels 

 the highway, may be seen a beaver flow with dead timber for a 

 stretch of about a quarter of a mile. 



8. Indian Lake Region. In this region none of the beaver flows 

 which I had opportunity to examine had been so destructive to 

 timber as the major ones mentioned for other regions. As an 

 example from this territory may be mentioned the private land 

 of Lot 41, in Township 17. On a small creek on this property 

 (McCabes Creek) were located three small dams which had been 

 torn open. As the result of a flow that had previously been caused
