Fishing Lake Ronkonkoma
Lake Ronkonkoma is the largest and perhaps best known of Long Island's freshwater lakes. Formed by ancient glaciers, portions of its irregular basin are unusually deep for Long Island, reaching 65 feet. However, most of the lake is less than 15 feet deep. Access is available from a concrete boat ramp off Victory Drive and a 100-foot accessible fishing pier off Shore Road.

What to watch for
Anglers should be aware that seasonal parking fees may apply for parking in certain locations around the lake.
What anglers say
According to the New York State Department of Environmental Conservation, the fishing pier is highly recommended as a shore fishing spot. This recommendation is due to its proximity to some of the best habitat in Lake Ronkonkoma.
