Flood Warning – Lake Temagami & Lake Nipissing Areas

Issued: May 26, 2026. In effect until: June 2, 2026 at 4:00 p.m.

The Ministry of Natural Resources has extended a Flood Warning for the Lake Temagami area and along the shoreline of Lake Nipissing.

What this means:

  • Water levels are high and flooding is already happening in some areas.
  • Additional flooding is still possible, especially if weather conditions change.
  • Shorelines, riverbanks, and low-lying areas are at risk.

What residents should do:

  • Stay alert and keep a close watch on local conditions.
  • Keep children and pets away from the water and supervise them at all times.
  • Be careful near shorelines—they may be slippery and unstable.
  • If you live in a low-lying or flood-prone area, prepare for possible flooding.
  • Watch for updates from Environment Canada and local authorities.

Water conditions:

  • Water levels remain above normal and are slowly decreasing, but still high.
  • Wind can push water onto shore, increasing the risk of flooding.
  • Debris such as logs and docks may be floating in the water.

Boating and recreation:

  • Use extreme caution when boating, kayaking, or using personal watercraft.
  • Stay away from dams, fast-moving water, and floating debris.
  • Avoid creating large waves near shorelines, which could cause damage.

Important reminder: Even though little rain is currently forecast, conditions can change quickly. High water levels mean the area remains vulnerable.

Definitions:

  • Flood Warning: Flooding is happening or expected very soon.
  • Flood Watch: Flooding could happen.
