SVCA issues flood outlook statement for Saugeen watershed

The Saugeen Valley Conservation Authority (SVCA) has issued a watershed conditions statement - flood outlook, and advising that mild temperatures and freezing rain can create the potential for flooding near water bodies throughout the Saugeen watershed.

Mild temperatures over the past several days have caused the snowpack to become dense, reducing its ability to absorb more water. Prolonged above-freezing temperatures may result in some snowmelt.

A freezing rain warning issued by Environment Canada and Climate Change advises that freezing rain is forecast in the area Wednesday (Feb. 18) with five to 10 millimetres (mm) of ice build-up expected. Temperatures are likely to remain slightly above freezing through Friday (Feb. 20) significant run-off is not expected.

With substantial river ice cover in the watershed, the primary concern over the next several days will be the weakening of river ice and potential for ice movement and jamming. Rising water levels may cause river ice to break up and move, creating the potential for ice jams to occur which can cause water levels to rise quickly, resulting in localized flooding.

While ice jams can form anywhere, municipal staff is advised to monitor locations of historic ice jamming and higher risk locations, such as bridge crossings, channel constrictions, areas of slow-moving water and sharp river bends. Municipal staff is also encouraged to monitor drainage systems, culverts, and low-lying areas and roads for flooding.

Water levels may rise quickly, and fast-moving water, unsafe ice, and slippery banks could make conditions dangerous near any river, stream, or shoreline. The public is reminded to stay away from all watercourses and structures, such as bridges, culverts, and dams.

SVCA staff will be closely monitoring watershed conditions. This message will remain in effect until Monday, Feb. 23, at 9 a.m., unless updated otherwise.
