other weed beds of any extent occur between Dresden and Long 

 point on the west shore of the lake. Here occurred several fairly 

 dense beds of Potamogeton with minor species intermingled, but 

 they are mostly near the shore and only in a few places extend 

 more than 300 yards from shore. The total area of these beds is 

 probably less than one-half square mile. Only a very few small 

 weed beds were noted at the south end of Seneca lake. These occur 

 near the inlet in the southeast corner. In Seneca lake, as in 

 Cayuga lake, only occasional narrow scattered weed beds were 

 found along the east and west shores. 



A rough estimate of the areas covered by weed beds would be 

 about six square miles in Cayuga lake and about two square miles 

 in Seneca lake.
