Lake Surveys Will Help Manage Fisheries

Natural Resources Crews Monitoring Northwestern Ontario Lakes

Provincial fisheries staff will be out on nearly 100 area lakes this summer, monitoring the lakes' health and gathering information to help manage fish populations effectively.

Crews will survey lakes north of Ignace, Dryden, Sioux Lookout, Red Lake and Kenora by plane and boat from May 16 to September 13, collecting water samples and setting nets.

Important dates:

  • Saturday, May 16 - Aircraft begin biweekly aerial angler surveys.
  • Tuesday, May 19 - Aircraft begin landing on survey lakes to collect water samples.
  • Monday, June 15 - Crews begin netting operations.
If you're on a lake that is being monitored and see Ministry of Natural Resources buoys, please avoid recreational activities in these areas. All nets will be clearly marked.

Quick Facts

  • Crews will survey lakes throughout Fisheries Management Zone 4, travelling as far north as St. Raphael Lake Provincial Park and Trout Lake.
  • About 1.4 million anglers fish in Ontario each year. They spend more than $2.3 billion in the province annually.
