About this water

The Nissequogue gives New York anglers a Long Island trout and sea-run brook-trout conservation page. It is close, unusual and fragile: brook trout rules are conservative, park rules apply in places, and the lower river/tidal context is not the same as a stocked inland trout stream. It belongs because NYC anglers will search for local trout options; it must be handled as conservation-first water.
