Mongaup River Guide Service

Status: active | Rating: 4.7/5 (3 reviews)

The Mongaup River tailwater below the Rio Reservoir dam fishes like a spring creek — cold, clear, and technical. We specialize in sight fishing to rising trout in gin-clear water. Not for the faint of heart, but incredibly rewarding.

Greg Flannery5/5Sight fishing to rising browns

The Mongaup tailwater is like a spring creek. Dave spotted fish for me and coached my casts. Landed three browns over 16 inches on tiny dries. Incredibly technical and rewarding.

Michelle Tran5/5Most challenging and rewarding trip

This is not easy fishing — the Mongaup is crystal clear and the fish are spooky. Dave is a master at it. Brought my A-game and still got humbled. Loved every minute.

Jim Callahan4/5Beautiful but technical

Dave warned me this was advanced-level fishing and he was right. Needed 7x tippet and perfect drifts. Caught two nice fish and lost several more. Will be back better prepared.

      "question": "What makes the Mongaup unique?",
      "answer": "The Mongaup River below the Rio Reservoir dam is essentially a spring creek — cold, clear water with aquatic vegetation and highly selective trout. Sight fishing with small dries and nymphs in 6x-7x tippet. It's the most technical water in the Catskills.",

      "answer": "Honestly, the Mongaup is best for intermediate to advanced anglers. The fish are wary and the water is clear — sloppy casts and heavy tippet won't work. That said, we welcome ambitious beginners who want a challenge.",
