Heavy rains in April and May have prompted the province to issue a flood warning for Dauphin Lake and a flood watch for lakes in Whiteshell Provincial Park.
Government flood forecasters are also keeping an eye on Lake Manitoba and Lake St. Martin, both of which could reach flood stage if there are heavy rains in the coming weeks.
Infrastructure and Transportation Minister Steve Ashton said Manitoba has served notice to the federal government that it may need to reopen an emergency outlet draining Lake St. Martin. The outlet was employed during the 2011 flood. Heavy equipment that can be used to open the channel is stationed there.
Double normal rainfall in western Manitoba in both April and May has also led to some overland flooding of farmland, the province said.
Heavy springtime rains in the Whiteshell Provincial Park caused some lake water levels to reach record highs. While most lake levels have been falling since then, there’s concern that forecast precipitation of 20 to 30 mm in the region over the next few days will cause levels to rise significantly.
