Flooding is possible for some areas of Mississauga.

Credit Valley Conservation (CVC) recently announced that a low pressure system will bring warmer weather, along with some rain, to the Credit River Watershed. The rain will begin on Thursday and persist into Friday.  

Temperatures are forecasted to rise to high single digits by Friday, with 10 to 15 mm of precipitation. The increased temperatures, along with rain, will result in significant melting of the remaining snow pack.

This weather shift could lead to higher runoff/flows and water levels along the Credit River and tributaries. Also, ice jams have existed since early February at the following locations along the Credit River:

  • Glen Williams at Main St
  • Ferndale
  • Meadowvale Park in Mississauga

CVC says there is a higher risk of flooding at these ice jams.  Also, increased flows and temperatures may result in mechanical and thermal break-up of the ice jams. As such, the potential for subsequent mobilization of ice jams to downstream areas remain high. Flooding along the Credit River and its major tributaries may occur in low-lying areas if ice jams are mobilized.

As a result, local streams, rivers, and shorelines remain dangerous, especially in the vicinity of culverts, bridges and dams.

Also, warmer than normal temperatures will reduce or eliminate ice cover in creeks and rivers, resulting in dangerous ice conditions. People are advised to stay away from all watercourses, and adults should ensure children and pets keep away at all times.

CVC says the watershed conditions statement for flood outlook will be in effect through Friday March 15, 2019 or until further notice.
