The Ministry of Natural Resources is keeping a close eye on parts of the Kam River.

Spokesperson Ross Johnston said the MNR and Ontario Power Generation are monitoring the high water levels in the Kaministiquia watershed.

Johnston noted there's a concern even if there's no fresh rainfall.

"You have to understand that the catchment area for Dog Lake is very large so the rain that fell on Sunday night is still moving towards Dog Lake," he said.

"We haven't seen it, it hasn't peaked yet. They're trying to maintain the level of the lake so that there isn't any flooding or damage to the road."

Johnston said travellers on Silver Falls Road may encounter water on the road surface in lower areas. The last time there was serious flooding in that part of the Kam watershed was in 2008.

Flood warning lifted

The Lakehead Region Conservation Authority (LCRA) has lifted its flood warning for some rural townships, including the municipalities of Neebing and Shuniah, and the townships of O'Connor, Gillies and Dorion.

The LRCA says watercourse levels are on the decline. But the warning still applies to the city of Thunder Bay, Oliver-Paipoonge and Conmee.

The LRCA said the Neebing River and Neebing-McIntyre Floodway have both crested, and should continue to decline over the next few days.

The LCRA also said the Kam River will maintain a high flow for an extended period.
