About Gravel River

The Gravel is a small north shore river that reaches Lake Superior between Nipigon and Rossport. The fishing is in its lower river, about 13 km of meanders from the falls down to a wide sand delta on Lake Superior. Lake-run rainbows come in from late April, peak in mid-May and hang on into June. Coaster brook trout work the delta and the nearby shoreline from mid-May, and the river is part of the stretch of shore where coasters have come back over the past 30 years.

Below the falls the river slows, meanders and cuts into its own sandy banks, so it fishes differently from the bedrock rivers to the east. Look for steelhead in the deeper bends and in the runs just below the falls, and drift a bead-head nymph and an egg pattern close to the bottom. In the clear, slow water at the mouth, a sculpin or smelt streamer on a sink tip finds coasters along the drop-offs. The gauge near Cavers sits just above the falls. The spring freshet colours the river, and it fishes best on the drop. It is a small river, so a few anglers fill it, and a cold, clear April day can find the fish still out in the lake.

The lower river and delta are in Gravel River Provincial Park, a nature reserve with no facilities where camping is not allowed. Below the falls a brook trout must be over 56 cm to keep, and rainbows are one a day on a sport licence and none on a conservation licence, so plan to release what you catch. Nipigon is 45 minutes west and Rossport is 15 minutes east, with motels and a provincial park campground at Rainbow Falls. If the Gravel is crowded, the Cypress and the Jackpine are just west along the highway, and the Steel is about an hour east.

Species

  • Steelhead
    Primary · Late Apr-Jun (peak mid-May) · About 2.3 kg (5 lb) on average

The Falls to Lake Superior

WadeSteelhead · Brook Trout

Below the falls the Gravel slows and meanders through its own sand deposits for about 13 km to a wide bird's-foot delta on Lake Superior, all inside Gravel River Provincial Park. The river cuts deeper bends where fish hold. No camping, and no facilities. Do not fish within 23 m below the falls.

Best for: Spring steelhead in the bends and below the falls from late April into June, and coaster brook trout on the delta from mid-May.

Best seasons

Late April into June for steelhead, peaking in mid-May. Coasters on the delta from mid-May until brook trout close on Labour Day. Read the gauge near Cavers: the spring freshet runs high and coloured, and the river fishes best as it drops and clears.

Regulations

The Gravel is in Zone 7. Rainbow trout: one a day on a sport licence, none on a conservation licence. Below the falls, brook trout are open from the fourth Saturday in April to Labour Day, one a day over 56 cm.

  • Rainbow trout (steelhead): open all year, S-1 and C-0.
  • Brook trout, Gravel River downstream from the falls: open from the fourth Saturday in April to Labour Day, S-1 and C-0, and it must be over 56 cm.
  • Pacific salmon: open all year, S-5 and C-2. All trout and salmon together: S-5 and C-2.
  • Province-wide: no fishing within 23 m downstream of the lower entrance to any fishway, obstruction or leap.

Ontario sells a sport licence (S) with full limits and a conservation licence (C) with reduced ones, and you need an Outdoors Card for any licence longer than one day. Buy them through HuntAndFishOntario.com. Check the Zone 7 page of the regulations summary before every trip.
