tains) is drained by Lackawaxen creek and its tributaries. 

 This drainage basin constitutes about two-thirds of the area 

 of Wayne county ; hence the Lackawaxen carries a large 

 amount of water. Its principal tributaries are : 



Dyeberry empties into it from the north at Honesdale ; 



Middle Branch comes in from the west at Hawley ; 



WaUenpaupack, from the south, pours a large volume of 

 water into it at the same locality over the cliffs of Paupack 

 Falls. 



A very insignificant area at the extreme south-eastern cor- 

 ner of Wayne is drained by a tributary of the Lehigh river. 



Lakes and Ponds. 



. A peculiarity of the drainage systems in both Wayne and 

 Susquehanna, but especially in Wayne, is the great number 

 of ponds and lakelets clustered around the heads of the 

 streams.and principally at the summits of the water-sheds. 



There are probably seventy-five of these in W^ayne, vary- 

 ing in size from an acre of surface up to 150. Many of 

 them are surrounded by dry banks of gravel extending down 

 to the water's edge, with no streams draining into them, and 

 only a narrow channel cut down through the gravel heap 

 for the outlet. Of course such a pond can be fed only by 

 springs rising from its bottom. Others again have small feed- 

 ing streams, and are often surrounded by a great expanse 

 of swamp or marshy lands, thus indicating the probable 

 greater expanse of the water in the past. 



The Delaware & Hudson Canal Co. has taken advantage 

 of these ancient drained lake basins to secure a constant 

 supply of water for their canal from Honesdale to the Dela- 

 ware river, during the dry seasons of summer and fall. 

 By throwing high dams across the narrow outlets of several 

 lakelets tributary to the Lackawaxen, the surplus rainfall 

 of winter and spring is thus caught and stored up to be 

 gradually let out through wickets in the dams when needed 

 in the summer. 



The following are the principal lakelets and ponds in Sus- 

 quehanna, with their elevation above tide (by barometer,) 

 and depth where known :
