Flood warnings remain in effect for parts of Waterloo Region and other areas in the Grand River watershed.

The Grand River Conservation Authority says reservoirs have reached their capacity, forcing them to increase discharges – which means higher water levels along the Grand, Conestogo and Speed rivers.

“We’ve had to increase the discharges from Conestogo Lake and Belwood Lake,” says GRCA spokesperson Dave Schultz.

“That’s going to mean high water levels in the central and southern part of the Grand River watershed for several days.”

Flood warnings are in place for Cambridge – where Water Street could flood south of Concession Street late Monday evening – and West Montrose.

River flows are expected to peak in the Galt portion of Cambridge late Monday night.

Elsewhere in Waterloo Region, the low-level bridge on Three Bridges Road near St. Jacobs remains closed, as do Black Bridge Road and the Highway 401 walking trail in Cambridge, as well as the Glasgow Street bridge in Conestogo.

To the south, Gilkison Street in Brantford remains closed with the river expected to crest around 6 a.m. Tuesday.

Six Nations 4th Line and Bateman Line are also closed, while Grand River Sports Drive south of York is being monitored.

Flows are expected to peak in Caledonia Tuesday evening, Cayuga early Wednesday morning and Dunnville around 9 a.m. Wednesday.

Further north, the Maitland Valley Conservation Authority is continuing a flood warning for the Harriston area.

Water levels were expected to peak Sunday in that region, but the MVCA says further increases are possible with significant rainfall.

Heavy rain did fall across the Saugeen Valley watershed, with some areas reporting as much as 35 mm of precipitation.

Most waterways under the umbrella of the Saugeen Valley Conservation Authority remain high, and will through the rest of the week, but aren’t expected to burst their banks any further.

As water crested through the Walkerton region, five streets in the area were closed.

Near Wingham, water levels are expected to continue rising until Tuesday, and then remain high through the week – with the potential for flooding in low-lying areas.

East of that area, flooded basements were reported Sunday night in Grand Valley, while part of County Road 25 was closed due to water cover.
