About Northwest Miramichi River

The Northwest Miramichi is the system's northern branch: smaller and quieter than the Southwest, with its own runs of salmon and grilse. It rises in the woods of northern New Brunswick, takes in the Little River and its own South Branch, and runs down past Wayerton and Trout Brook to Red Bank, where the Little Southwest joins it, and on to the Sunny Corner bridge. The upper river is reached by forest roads. Route 430 crosses at Miners Bridge, and Route 425 crosses at Red Bank.

The lower river opens to bright salmon on May 16, and the water above the Little River opens June 10. The main runs come in July, and the fall fish run into the October 15 close below the Little River. Read the Trout Brook gauge. It also carries a water temperature, so this page shows where the river stands against DFO's warm-water line. In hot summers the salmon stack up at the cold brook mouths, and DFO closes the protected pools at Wildcat Brook, Trout Brook and Pat's Brook until the water cools. The pool at the mouth of Sutherland Brook closes every year on July 1.

It is fly only for salmon, catch and release, two bright fish a day. Brook trout are common through the river. Non-residents fish with a licensed guide.

Best seasons

July for the main run, and September into the October 15 close for fall fish on the lower river. A summer rise brings fish up from Red Bank. In a heat wave, watch the Trout Brook water temperature: DFO acts on warm mornings, and the cold-water pools close first.
