Mayor Sam Katz visited Kilkenny Drive in south Winnipeg Monday as flood preparations were underway.
The city said the need for volunteers has eased somewhat, but more help will be needed in the days ahead, to help protect some Winnipeg homes.
"The real task has been getting volunteers during the week…we're fortunate people do come out during the weekend, they're not working," said Katz.
"We're very fortunate that…volunteers from schools, have been coming out. Because we would have been in serious trouble without them last week, I can assure you of that," said Katz.
Emergency coordinator Randy Hull said the city is also advising homeowners about people going door-to-door offering to help build dikes, but who aren't with the city.
Hull said it's not a scam, but it's not helping either.
"We've had a couple of people come to homeowners. They thought they were city people and they weren't. (We) want to keep the operation within the city," said Randy Hull.
He advised homeowners should ask for photo identification that will clearly show they are from the city.
Those wanting to help out with sandbag efforts are also being asked to call the city's 311 phone line.
Officials are bracing for water from North Dakota to move into the province.
Randy Hull said Winnipeg still needs to prepare for a worst-case scenario.
"We still know there's a wall of water coming from that American portion of the Red River. We're just not certain what (amount) that might be," said Hull.
Areas such as those around Kildonan Drive need sandbagging, said officials.
