April showers have brought … higher water levels in Lake Ontario

Posted by on

BURLINGTON – Even though the month of April is still not complete, it has already been a wetter month than usual for area residents. Conservation Halton rain gauges confirm that some areas within the watershed have received anywhere from 130% to 200% of the long term average precipitation amount for the month of April.

Given the above average precipitation across much of Ontario, not only in April but during the milder winter, current water levels within Lake Ontario are higher than normal. Elevated lake levels are expected to continue over the next several months prior to receding.

Accordingly, Conservation Halton is asking all residents and children to exercise caution along lakefront areas during this period. Elevated lake levels combined with wave activity can make these areas potentially dangerous.

Conservation Halton’s Flood Forecasting and Operations program monitors weather forecasts for high winds and storm surge along with wave heights. Staff is also working closely with shoreline municipalities to provide detailed monitoring information and will issue flood messages as required. We encourage the public to monitor our website for further updates.

About Conservation Halton’s Flood Forecasting and Operations Program

Conservation Halton provides a flood forecasting and operations program to reduce the risk of property damage and loss of life due to flooding.

When flooding is possible or about to occur, Conservation Halton issues flood messages to municipal emergency management officials, school boards, police and EMS as well as the media. The municipal officials then take action to warn local residents.

Conservation Halton is responsible for the maintenance and operation of four major flood control dams (Kelso, Hilton Falls, Scotch Block and Mountsberg) and over 12 kilometers of flood conveyance channels (Sixteen Mile Creek through Milton, Morrison-Wedgewood diversion in Oakville and the Rambo-Hager diversion in Burlington).
