The province said Monday that Lake Manitoba is currently sitting at its highest level in 50 years.
Officials also issued an advisory Monday that a strong wind-warning is in effect for Lake Manitoba, Lake Winnipeg and Lake Winnipegosis, which could affect water levels.
Officials said strong winds over the next three to four days are expected on all three lakes, along with affecting Shoal Lakes and Dauphin, Oak, Pelican and Rock lakes, in addition to other lakes across Manitoba.
RMs are being contacted and residents are advised to prepare for "wind-effected lake levels," said the province.
Officials said an unstable weather system will bring rain across much of southern Manitoba on Monday. Officials will assess the impacts of the storm as conditions develop.
Farmers in the Langruth area expressed concerns about high water levels on Monday.
About 4,000 acres of Tom Tiechroeb's pasture land are already flooded.
He said too much water is flowing into Lake Manitoba from the Portage Diversion. He said the flow out of the lake should be increased at the Fairford Dam.
"If you are going to fill a tub with a four-inch line and drain it with a two-inch line, what's going to happen? Your house is going to flood," said Tiechroeb.
Joe Johnson said his farmland has been reduced to marsh. He said he's lost hundreds of thousands of dollars over the past 15 years to flooding and also blames the Portage Diversion.
"Our land is our retirement pension and our pension has been blown out of the water - blown into the water would be a better way of putting it - because who…wants to buy my farm?" asked Johnson.
The province admitted that levels on Lake Manitoba have increased because of the diversion, but said it would have happened anyways because of natural in-flows into the lake.
Provincial officials are set to hold a meeting with the public and municipal officials on Wednesday in Langruth to discuss ideas for possible long-term solutions.
