About Steel River

The Steel is one of the north shore rivers that steelhead anglers drive Highway 17 for. Below Santoy Lake it runs a short, steep course through bedrock and boulder runs to Lake Superior, about 15 km east of Terrace Bay as the crow flies. Lake-run rainbows push in from the lake in late April, peak in mid-May and keep coming into June, and they can climb as far as the Golden Staircase at Santoy Lake's outflow. Drop-back fish that have spawned feed hard on their way out in late May and June. Coaster brook trout work the shoreline off the mouth from mid-May into summer.

It is a wading river, with pools strung between rapids. Steelhead rest in the soft water between long rapids and in the seams behind boulders, so read the water and fish the slots, not the white water. A bead-head nymph with an egg pattern behind it, drifted near the bottom, is the standard north shore rig on an 8 weight. Swing streamers for drop-backs. The water stays ice cold well into June, so wear insulated waders, and expect slick bedrock and fast water. The gauge below Santoy Lake reads the river's flow. A spring freshet that runs high and coloured is hard to fish, and the river comes into shape as it drops and clears.

The pools at the Highway 17 bridge are the community holes, and when the run is on a dozen anglers can line one pool. Walk upstream or down on the angler trails and you will usually find room. Rainbows are one a day on a sport licence and none on a conservation licence, and a brook trout must be over 56 cm to keep, so most fish here go back. Above Santoy Lake the Steel is a canoe route in a provincial waterway park with no facilities. Terrace Bay and Marathon have motels and gas, and there is little else between them.

Species

    Wild lake-run rainbows. Fresh fish arrive from late April, and drop-backs that have spawned feed on their way back to the lake into June. Land them fast and release them in the water.

  • Brook Trout

    Coaster brook trout cruise the Lake Superior shoreline near the mouth. Below the Golden Staircase a brook trout must be over 56 cm to keep, one a day, so release them.

Sections

2 reaches

Golden Staircase to Highway 17

WadeSteelhead

From the Golden Staircase at Santoy Lake's outflow down about 9 km of bedrock, boulder runs and pools to the Highway 17 bridge. Angler trails follow the river up from the highway. Do not fish within 23 m below the falls at the top.

Best for: Spring steelhead from late April into June on a nymph and egg rig, and drop-back steelhead on streamers.

Highway 17 to Lake Superior

WadeSteelhead · Brook Trout

The last kilometre below the bridge to the mouth. The bridge pools are the most fished water on the river when the run is on. Fish milling off the mouth can be reached from shore.

Best for: Fresh steelhead coming in from the lake, and coaster brook trout off the mouth from mid-May.

Best seasons

Late April through June for spring steelhead, with the peak in mid-May and drop-backs into June. Coasters near the mouth from mid-May into summer. Read the gauge below Santoy Lake: the river runs high and coloured during the spring freshet and fishes best once it starts to drop and clear.
