About Wanaque River

The Wanaque River below Wanaque Reservoir is a legitimate tailwater fishery in Passaic County that holds brown trout year-round thanks to cold, consistent releases from the deep reservoir. It's a smaller, technical stream that rewards careful wading and precise presentations.

Regulations

Tailwater fishery — flows are reservoir-controlled and can change rapidly. Standard NJ trout regulations apply; confirm current season dates and any access restrictions along North Jersey District Water Supply Commission land bordering the river. CFS alone does not indicate fishability — check dam release schedules. NOTE: USGS gauge 01388000 is unverified — flow data may be stale or unavailable; check with local outfitters as backup.
