​SVCA issues water safety notice with possibility of localized flooding

The Saugeen Valley Conservation Authority (SVCA) has issued a water safety notice, warning of the possibility of localized flooding.

Persistent cold temperatures and significant snowfall have resulted in an above-average snowpack and formation of thick ice on local streams and rivers. The snowpack is currently holding an average of 124 millimetres (mm) of water, with areas ranging from 87-180 mm.

The current thickness of ice on the Saugeen River is estimated to be between 30-37 centimetres (cm). An extensive snowpack and thick river ice leading into spring can bring significant flood potential due to heavy runoff and ice jams.

The regional forecast indicates above freezing temperatures and 15-25 mm of rain through Wednesday night. The melting of the snowpack, accompanied by rain, is expected to increase water levels beginning Tuesday and continuing into next week.

Elevated water levels, in combination with thick river ice, may increase the risk of ice jams should significant break-up occur. Temperatures are forecast to quickly return to freezing later this week, which may diminish the potential of flooding; however, dangerous conditions can be expected due to weakening ice and unstable snow around riverbanks.

The public is reminded to stay away from all watercourses and structures, such as bridges, culverts, and dams. Municipal staff should monitor flood-prone areas for ice jams and localized flooding.

SVCA staff will be closely monitoring watershed conditions and will provide an update if conditions change. This message will remain in effect until 4 p.m., Monday, March 10, unless otherwise updated.
