Lake Ronkonkoma

Suffolk County, New York

moon phase
Sun times displayed in .
Formed by ancient glaciers, Lake Ronkonkoma is the largest and perhaps best known of Long Island's freshwater lakes. Portions of its irregular basin are unusually deep for Long Island (65 feet), but most of the lake is less than 15 feet deep.

As a rule of thumb, it is unproductive to fish deeper than 15 feet in Lake Ronkonkoma because there is seldom enough dissolved oxygen to sustain fish beyond this depth. The primary gamefish are largemouth bass and smallmouth bass. Lake Ronkonkoma holds large bass, but locating them is a challenge due to the scarcity of natural structure to attract these fish. Stumps have been placed into the lake for habitat enhancement (see below). Chain pickerel are extremely rare.

In the last two decades, white perch and yellow perch populations have increased to the point of upsetting the ecological balance of the lake. To control these species, the DEC began stocking walleye in 1994. Walleye over 27 inches long can be caught and provide a good targeted fishery. For more information on this species see the walleye fact sheet. (PDF) Lake Ronkonkoma also contains sunfish and crappie though large specimens are not common.
