7. Green Pond: The smallest natural lake within the boundaries 

 of the Park lies just east of Stahahe Lake. It is a small circular 

 body of water with a diameter of a tenth of a mile and a maximum 

 depth of eight feet. The encroachment of vegetation from the 

 shores and the silting up of the bottom have reached an advanced 

 stage, and the lake will disappear completely in a short time. 



8. Highland or Hessian Lake: Found in the extreme eastern part 

 of the Park, just a few hundred feet back from the Hudson River 

 and 350 feet above it. It is a natural lake bearing the old Indian 

 name Sinnipink, according to Cole. The length is .52 miles, breadth 

 .15 miles, and depth about 35 feet. 



9. Island Lake: It lies in the southern part of the Harriman 

 estate and is one of the smallest natural lakes studied. At the 

 same time its depth is nearly three times that of any other lake of 

 the region, that was visited. It is a summit lake which originally 

 drained both north and south, but the construction of a dam raised 

 the water-level three or four feet and caused all of the water to 

 flow into Echo lake. It has a length of .35 of a mile and a breadth 

 of a quarter of a mile. The deepest part of the lake is 126 feet and 

 an average of 35 soundings taken in the northern half was 91 feet. 



10. II. Upper and Lower Kanahwauke Lakes: These lakes are 

 wholly artificial and were constructed by the Park authorities in 

 1914 by building two dams across the valley of Stillwater Creek, 

 which rises in Little Long Pond. Both of these lakes are shallow 

 and about a mile long. 



12. Little Dam Lake : Made by damming the stream flowing from 

 Lake Mombasha in the northern part of Tuxedo Township. Rutten- 

 ber and Clark state that the Southfield works were established in 

 1805 or 1806, and the presumption is that this old mill-pond was built 

 at about that time. At present it is a very shallow body of water 

 with the macrophytic vegetation encroaching from all sides. It is 

 rather irregular in shape with a maximum length of three fourths 

 of a mile and a breadth of an eighth of a mile. 



13. Little Long Pond: The largest natural lake within the bound- 

 aries of the Park lies in the western portion between Cedar and 

 Stahahe Lakes. It is shown on the Sterling map of 1779 as Long 

 Pond. In 1914 the depth of the water was increased about three 

 feet by the construction of a dam at the outlet. The dimensions of 

 the lake are thirty-five by eleven hundredths of a mile; the average 

 depth is 21 feet and the maximum depth 33 feet. 



14. Lo7tg Pond: Another body of water outside of the Park 

 limits is about three miles west of Highland Falls. It is a natural 

 lake shown on all old maps, but I am unable to find whether or not 

 its level has been raised by dams. It is .56 of a mile long and .15 

 broad. 



15. Mine Lake: A half mile east of Popolopen Pond, is undoubt- 

 edly an artificial pond built to furnish power for the Forest of Dean
