An Ecological Study of Buckeye Lake. 17 



mouth the banks are low, flat and wet and are covered with a 

 dense growth of Hibiscus moscheutos and with a few Sambucus 

 canadensis and SaHx nigra shrubs ; this is followed lakeward 

 by a mixed Hibiscus-Scirpus zone which passes into a dense 

 growth of Typha latifolia. In the more open water Nelumbo 

 lutea becomes dominant. Altho the feeder has so little current, 

 enough sediment has been deposited during the eighty years of 

 its existence to form a broad low delta.

 at the center are on the delta. 



The levee which was the eastern embankment of the canal 

 and the western of the old reservoir, is intact only from the 

 southern end to Onion Island. The remainder consists of de- 

 tached portions with broad open water channels between them. 

 These broken portions bear a few trees, willows and elms. 

 Some places are so broken down that the trees are standing in 

 water. From the margin of the lake to Lieb's Island the levee 

 is clothed with large trees on the south side and a shrub zone, 

 Sambucus and Salix nigra on the north. The shrub zone is in- 

 teresting as it has had undisturbed possession only since the 

 abandoning of the use of canal boats.
