About Paulinskill River

The Paulinskill flows through Warren County's farm country before joining the Delaware River. It's a solid stocked trout river with a mix of flat water and productive riffles, best fished in spring before water temperatures climb. The river corridor includes sections of the Paulinskill Valley Trail, making access straightforward for wade fishers.
