flood watch graphic - high water on a creek

Cataraqui Conservation has issued a Flood Watch today for the Cataraqui Watershed and Gananoque River System, due to the excessive amount of rainfall in recent days, and the increased likelihood of flooding in certain portions of the region.

Weather Situation: Throughout the region, 55 to 77 mm of rain has fallen since April 29. This represents about a month’s worth of rain in only two or three days. There may be some additional rainfall over the next few days before drier conditions arrive.

Risks: This has meant that there are high flows on watercourses and high-water levels on inland lakes. As well, lake levels will continue to rise for several days. Water Managers have increased discharge and continue to monitor levels closely to limit, as much as possible, negative impacts from the rainfall runoff.

Widespread flooding is NOT expected. However, flooding of low-lying areas IS expected.

Specific locations where water levels are exceptionally high include*:

Cataraqui Watershed

  • Loughborough Lake
  • Buck Lake
  • Canoe Lake
  • Kingsford Lake
  • Devil Lake
  • Newboro Lake
  • Opinicon Lake
  • Sand Lake
  • Cranberry Lake
  • Dog Lake
  • Colonel By Lake

Gananoque River System

  • Upper Beverley Lake & Delta
  • Lower Beverley Lake
  • Singleton Lake
  • Charleston Lake
  • Gananoque Lake
  • Gananoque River – the reach between Marble Rock Dam downstream to the 401 causeway (includes Marble Rock Road)

*Connected lakes and watercourses, associated with the above list, may also be affected.

Residents in flood-prone or low-lying areas, historically susceptible to flooding, are advised to remove items stored in the floodplains of area watercourses and lakes.

If you witness flooding and/or require assistance your first point of contact is the local municipality. Affected residents are advised that sand and bags are available at the following municipal locations (separate municipalities):

Cataraqui Conservation is urging caution around all dams (inflow and outflow channels) and fast-flowing watercourses. Respect the hazards in these areas by obeying all warning signs, and keep away from booms, buoys, and barriers. Stay well back from the water’s edge above and below dams and hydroelectric stations. Creek banks and lake shorelines may be slippery, increasing the chance of falling in.

Staff will continue to monitor conditions and forecasts and update statements as needed. This Flood Watch will remain in effect until (or updated before) Wednesday, May 10, 2023, at 11:59 PM.
