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.

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.
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.
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.
