SVCA issues flood outlook statement for Saugeen Watershed

The Saugeen Valley Conservation Authority (SVCA) advises that forecasted precipitation, above freezing temperatures, and associated snowmelt are likely to result in above-seasonal water levels throughout the Saugeen Watershed over the next several days.

Temperatures are expected to rise above freezing over the next several days and will be accompanied by 20-25 millimetres (mm) of rain between Wednesday, Jan. 24, and Thursday, Jan. 25. As of Jan. 22, the average water content contained within the snowpack was 45 mm. Melting snow in combination with forecasted precipitation may result in 65-70 mm of run-off.

In some areas of the watershed, rainfall may be absorbed in the snowpack; however, sustained warm temperatures and primarily frozen soils will cause the melting snow to run-off quickly to local watercourses.

An increase in water levels will also create the potential for break-up and movement of river ice. This could result in ice jams and flooding in non-traditional areas. Ice jams can occur anywhere within a watercourse but are more likely in areas near culverts, bridges, and channel restrictions.

While significant flooding is not expected, watercourses could reach or exceed bank-full conditions, with minor flooding in low-lying areas. More extensive flooding is possible should the watershed receive temperatures and rainfall amounts greater than what is currently forecast.

The public is reminded to stay away from all watercourses and structures, such as bridges, culverts, and dams. High water levels, fast-flowing water, and slippery conditions along watercourse banks are extremely dangerous. Any remaining ice on our watercourses, during or following this event, will be unsafe to be on.

Municipal and county staff should monitor areas that are traditionally prone to flooding. SVCA staff will be closely monitoring the situation and will provide an update if conditions change.

This message will remain in effect until Sunday, Jan. 28. To report flooding in your area, visit the SVCA website: saugeenconservation.ca/reportflood.
