dense beds off the northern and northeastern shores. The bottom is 

 mainly sand and fibrous peat. Over the peat bottom, generally toward 

 the middle of the lake, thick stands of bushy-pondweed, Najas guadalu- 

 pensis, occur and a green alga, Nitella sp., is seasonally abundant. 

 Average depth of the lake is 2.3 m, and maximum depth is 3.3 m. 



In addition to Big Creek, the lake is fed by three smaller streams: 

 Little, Second, and Third creeks. Acid water from these streams is neu- 

 tralized by the calcareous Waccamaw limestone formation, which 

 underlies the lake and is exposed along the north shore (Frey 1951).
