The Ministry of Natural Resources (MNR) storm surge model forecast for the eastern end of Lake Erie is indicating a rise in lake levels to above the threshold of Lake Erie Flood Zone 1. The passage of a strong low-pressure system is expected to bring high winds to Lake Erie on Monday.

The Grand River Conservation Authority (GRCA) is issuing a Flood Watch message for Nith River Subwatershed and a Watershed Conditions – Water Safety message for the remainder of the Grand River watershed remains in effect.

The Grand River Conservation Authority (GRCA) is concerned about the use of frozen natural water bodies for on-ice activities such as skating and ice fishing. Recent cold temperatures and early-season snowfall have resulted in the formation of thin ice on local rivers, reservoirs, ponds, and lakes across the watershed. While ice may appear to be forming earlier than in previous years, ice conditions remain highly unstable, unpredictable, and unsafe for any type of recreation.

It is important to note that river systems, reservoirs, and water control structures experience fluctuating water levels and variable flows that prevent stable ice formation. While colder temperatures allow for some ice formation, daily changes in temperature, wind, precipitation and underwater currents greatly affect ice conditions. In many areas, snow cover can also insulate the ice surface, slowing the freezing process and creating hidden weak spots.

The Grand River Conservation Authority (GRCA) held its Annual Workshop for municipal participants of its Watershed-wide Wastewater Optimization Program (WWOP) on November 13, 2025, at its Administration Centre in Cambridge.

The booms and buoys are in addition to permanent signage that is installed at GRCA-owned dams warning people of dangers around dams and alerting paddlers and boaters of portage access points.

Water users in parts of Brant County, Six Nations of the Grand River, Mississaugas of the Credit First Nation, Haldimand County and Norfolk County in the McKenzie Creek sub-watershed are being asked to voluntarily reduce their water consumption by 20 per cent due to continued dry conditions. The current Level 2 low water condition declared for Whitemans Creek and Lower Nith sub-watersheds on August 29, 2025 remains in effect. The rest of the Grand River watershed remains in a Level 1 condition, as declared on August 22, 2025.
