Floodwaters on the Ottawa River are now forecast to creep almost as high as the worst of the flooding in May 2017.

The latest flood forecast for the Ottawa River has pushed back the water's expected peak to this weekend, with many areas in line for flooding just below what the region saw in May 2017.

The Ottawa River Regulation Planning Board's latest predictions calls for the river's floods to peak between Saturday and Monday, along sections of the river from Pembroke to Hawkesbury.

Water levels in Ottawa and Gatineau are expected to stay below the peak floods of May 2017, but by only by a few centimetres. Areas farther upstream, in Mattawa and Pembroke, are expected to see river levels rise even higher than in 2017.

Areas along rivers that lead into the Ottawa River are also seeing flooding. Several locations in Lanark County -- including Carleton Place, Mississippi Mills and Lanark Village have seen rivers burst their banks and roads covered by floodwater.
