About Mattagami River

Mattagami River is a river flowing through Ontario, Canada. River fishing rewards anglers who learn to read current — fish hold in the seams between fast and slow water, behind rocks and submerged logs, and at the heads and tails of pools. At Mattagami River, working a lure or fly down-and-across the current usually outperforms casting straight upstream. Higher water concentrates fish; clear, low water makes them spookier.

Fishing Techniques

  • For Northern pike

    Vary your retrieval speed and add pauses to entice strikes, especially in colder water.

  • For Walleye

    Focus your efforts around dawn and dusk, as walleye are typically more active during these low-light periods; use a slow, deliberate retrieve, as walleye often prefer a subtle presentation.

  • For Smallmouth bass

    Focus your fishing efforts around rocky structures, ledges, and areas with current, as smallmouth bass prefer these habitats.
