Cold temperatures have slowed runoff and will cause declining water levels in watershed lakes and streams through the weekend.

There is enough water moving through the system from the melt and rain that flows are still increasing in some tributaries. This will tail off today and levels can be expected to decline through the weekend. Weather forecasts indicate another warmup with some rain next week that could cause flows to increase again.

The warm temperatures and increased flows caused the ice on all waterbodies to become unstable. With refreezing occurring, new ice will be forming. However, it will take a few days for a consistent ice sheet to develop. All watershed residents, especially children, are advised to stay off of the ice on rivers and streams and avoid icy or wet streambanks where footing can be difficult.

Conservation Authority staff will continue to monitor conditions and issue further statements as conditions warrant.


RVCA Watershed Conditions Statements:

  • Water Safety – High flows, unstable banks, melting ice or other factors that could be dangerous for recreational users such as anglers, canoeists, hikers, children, pets, etc. Flooding is not expected.
  • Flood Outlook – Early notice of the potential for flooding based on weather forecasts, calling for heavy rain, snow melt, high winds or other conditions that could lead to high runoff, cause ice jams and/or lakeshore flooding or erosion.
  • Flood Watch – Flooding is possible in specific watercourses or municipalities. Municipalities, emergency services and individuals in flood prone areas should prepare.
  • Flood Warning – Flooding is imminent or already occurring in area watercourses.
