The Productivity of Fish Food in Oneida Lake 35 



feet or more and must be upwards of a hundred feet wide. 

 How far this streak of gravel may extend is not known as 

 only three dredgings were made. It is probably to be found 

 for a long distance east and west bordering the south shore 

 of the lake. Mr. Fred Becker and otlier fishermen first 

 reported this deposit to me and dredging corroborated their 

 observations. 



Other boulder areas of small extent occur at the west end of 

 Dunham Island and on several shoals between Dunham and 

 Frenchman Islands. On the boulder shores, especially when 

 the lake lies at the bottom of a land terrace, as the shore east 

 from Norcross Point, a line of boulders is usually found which 

 is probably comparable to the ice rampart bordering the shores 

 of other lakes. A typical ice rampart, however, was not 

 observed by the writer on the shores of Oneida Lake, though 

 such may exist. 



Sand Bottom Areas. Sand areas are of wide extent in 

 Lower South Bay, occurring in places where there is more or 

 less protection from the waves, either by natural barriers or 

 by depth of water. Sand usually borders the boulder and 

 gravel territory where the water is five or six feet deep. On 

 these sand bottoms the water ranges from a few inches to five 

 or six feet in depth but in one spot it was found at a depth of 

 14 feet. Extensive sand areas occur on the south shore of 

 Long Point, from the end westward for nearly 3,500 feet. 

 These are from 150 to 400 feet wide. An area fully 900 feet 

 long and having a maximum width of 400 feet occupies the 

 head of Short Point Bay. At the end of Conway Point, in 

 Conway Bay, and on Short Point, large sand bottom areas 

 occur. The west shore of Lower South Bay, from south of 

 Conway's house to the southwest corner of the bay, a distance 

 of about 4,000 feet, has a border of sandy beach 50 to 100 feet 

 in width. The largest sand bottom areas occur on the south 

 shore of the bay, extending from Thierre's landing eastward to 

 Norcross Point, embracing an area of approximately 38.34 

 acres, or 1,670,000 square feet. 



On the large sand bottom areas bordering the west side of 

 Short Point Bay, where there is little vegetation, the sand is
