SIX NATIONS OF THE GRAND RIVER- Flood warnings have been issued for the southern Grand River watershed with Six Nations experiencing flooding along Fourth Line Road today.
Fourth Line has been closed with signs posted warning drivers of flooding. Flooding along Fourth Line Road and along Newport Road in Brant County was caused by ice jams in the river, the Grand River Conservation Authority said in a release Wednesday.
Meanwhile River levels and flows have peaked and are receding in the northern and central Grand River watershed, north of Brantford. The Nith River through Ayr is expected to peak late Wednesday afternoon/early evening while the lower Nith River will peak Wednesday evening.Flows through the community of Ayr on the Nith River are expected to peak below Warning Zone 1.River flows reached their peak in the Grand River through Brantford around 8:00 pm Tuesday night.
The GRCA said flows are forecast to peak through Cayuga on Wednesday evening and through Dunnville and Port Maitland early Thursday morning. Much of the river reach through Cayuga is open and free of ice at this time. Ice has moved downstream of the community of Cayuga but is still intact in the river between Dunnville and Cayuga.
-The southern Grand River downstream of Brantford: River ice is still present in the southern river. Potential for ice jams and flooding is
possible in low lying areas that are typically prone to flooding. These areas include River Drive (south of Caledonia), Sims Lock Road, Grand Sports Road, Town of Cayuga and community of Port Maitland. Haldimand flood co-ordinators are asked to monitor these locations through Wednesday evening. If the ice sheet upstream of Caledonia dam
releases, ice jam flooding could result in these areas.
-GRCA’s major reservoirs at Belwood, Conestogo, Guelph, Luther, Woolwich, Laurel, and Shade’s Mills are being used to manage runoff from this event and reduce flooding downstream of these reservoirs. Small increases in discharge were initiated at Belwood, Conestogo and Guelph reservoirs this morning. River flows will remain high over the next few days.
Stay Safe-The public is reminded to exercise extreme caution around all water bodies. Banks adjacent to rivers and creeks are very slippery at this time and, when combined with current weather conditions, pose a serious hazard. Parents are encouraged to keep their children and pets away from all watercourses and off frozen water bodies, which will be weakened as a result of the warming trend.
This message will remain in effect until noon on Thursday February 7, 2019. Updated flood messages will be issued as conditions develop and better forecast information becomes available.
