Enough rain has fallen this week to leave some low-lying parks and roads flooded – and authorities are watching closely to see if water levels increase.

One of the most notable flooded areas in Waterloo is Cambridge’s Riverside Park, where the overflowing Speed River made many parts of the park inaccessible.

The low-level bridge over the Conestogo River in St. Jacobs has also been closed due to high water, as has Black Bridge Road in Cambridge.

According to Environment Canada, nearly 40 mm of rain fell in Kitchener on Thursday, as a low-pressure system made its way through the area.

Brantford saw 37.5 mm of rainfall, while the total in Elora stood at 32.5 mm.

Higher totals were reported in midwestern Ontario, including 63.7 mm in Durham, 59.9 mm in Seaforth, and 57.9 mm in Kincardine.

The Grand River Conservation Authority said Friday afternoon that water levels had peaked in the northern parts of the watershed, but would remain high through the weekend.

The Grand was expected to peak at midnight in Brantford, and 24 hours later in Dunnville. The Nith River was expected to hit its peak in Ayr at midnight.

In Six Nations and points downstream, the GRCA warned of potential flooding in summer campgrounds and other low-lying areas, including on the 4th Line at Bateman Line.

Lions Park in Burford was closed Friday due to flooding.

Elsewhere, the Saugeen Valley Conservation Authority warned Friday morning that water levels in the Saugeen River and its tributaries had yet to crest.

The highest water levels in that area were expected to be seen later in the day – with low-lying areas in Hanover, Paisley and further downstream most at risk of flooding.

North of Durham, Highway 6 was closed Friday around Williamsford due to flooding. Several homes in the area were also evacuated.
