About Main River

Main River rises in the Long Range uplands beside Gros Morne National Park and runs east to the sea at Sop's Arm, in White Bay. It was named a Canadian Heritage River for its wild, undammed course, and it carries a run of Atlantic salmon and grilse into some of the quietest country on the island. DFO lists it under the Sop's Arm River, with Main, Doucer's and Natlin's and their tributaries.

This page covers the lower river, from the Paradise Pool gauge down to Sop's Arm. Above it the river is canoe country. The river rises and falls fast with rain off the uplands. As a rough guide from the Paradise Pool gauge, it fishes well between about 7 and 50 m³/s and is high over about 140. Wet flies and a riffling hitch take grilse in July, and a dry fly earns its place in low, clear water.

It is Class 4: two salmon a season under 63 cm on tags 1 and 2, and 3 released a day. Sunshine Pool, from 150 m below to 300 m above the falls, is catch and release only, and so is the Northwest Branch. No one may fish within 23 m below the falls at Sunshine Pool or Wardens Pool, and the Northwest Branch is closed from 300 m below to 300 m above the falls at Wardens Pool. A non-resident needs a licensed guide or a resident relative. Services are thin: plan on Deer Lake or Baie Verte for supplies.

Species

  • Atlantic Salmon

Licence
A Newfoundland and Labrador inland fishery licence to take salmon: $23 for a resident, $80 for a non-resident, plus the vendor's $3 fee and HST. It is needed for catch and release too. A non-resident may fish a scheduled salmon river only with a licensed guide or a resident direct relative.
Tags
Tags 1 and 2 (red and green) are valid: keep at most two salmon in the season, each under 63 cm. Lock the tag through the gills and mouth and cut out the month and day as soon as you keep a fish. You may also catch and release 3 salmon a day.
River class
Class 4 (Sop's Arm River, including Main, Doucer's, Natlin's, Corner Brook and all tributaries).
  • Artificial fly only on scheduled salmon rivers, with a single barbless hook, one rod and one hook at a time. No weight, spinner or bait on the fly.
  • Salmon angling from one hour before sunrise to one hour after sunset only.
  • No salmon of 63 cm or more may be kept. Release every large salmon, every black salmon (kelt) and every salmon under 30 cm.
  • No angling within 23 m downstream of a fishway, canal, obstacle or falls.
  • Environmental protocol: when the water passes 20.0 °C over two to three days, DFO may close the river from 10:01 a.m. to one hour before sunrise until it cools (18.0 °C on Class 0 catch-and-release water). Low water can close a river too. Check the In-Season River Status before you fish.
  • Keep a salmon angling log and return it to DFO at the end of the season.
  • Catch and release only on Sunshine Pool, from 150 m below to 300 m above the falls, and on the Northwest Branch of Main River.
  • No angling within 23 m downstream of any falls, at both Sunshine Pool and Wardens Pool.

In-season closures for warm or low water are posted on DFO's In-Season River Status. Rules change each year, so read the current Anglers' Guide before you fish.
