Fishing Information

Knapps Lake is a small pond located in Islip. It is quite shallow and in the summer it becomes thickly covered with aquatic plants. The predominant fish species are common carp, largemouth bass and sunfish. The fish tend to be small. While large bass have been caught at Knapps Lake, they are not common. Few exceed 12 inches.
