The biggest brown trout in the Catskills, and perhaps the east, swim in the Pepacton. The reservoir is part of the New York City water supply system, and requires a permit to access. Fish from shore or rowboat just about anywhere in the spring, then go deep during the summer. Live bait fish (usually sawbellies) and shiny spoons (most notably Krocodiles) are proven methods. Water levels fluctuate depending on seasonal rainfall fluctuations. Beware of mercury contamination and other State health advisories.
