About St. Mary River

St. Mary River cuts through Alberta, Canada and offers classic stream fishing. The local patterns are the universal river patterns: fish the heads of pools at first light, the deep slow water in the middle of the day, and the tail-outs as light fades. Light tackle and a careful drift go a long way at St. Mary River — heavy splashes spook a whole pool.

Fishing Techniques

  • For Northern pike

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

  • For Westlope cutthroat trout

    Westlope cutthroat trout are often found in clear, cold streams; fish upstream, presenting your bait or lure naturally and avoiding spooking the fish by keeping a low profile.

  • For Rainbow trout

    Vary your retrieve speed when using spinners to find what triggers a strike; sometimes a slow, steady retrieve works best, while other times a faster, erratic retrieve is more effective.
