Watershed Conditions Statement – March 11, 2013 – Flood Event 3, Bulletin 1

March 11, 2013

Highlights:

  • 20 to 25 mm of Precipitation for today and tomorrowTop of bank water levels on local watercourses
  • Slippery stream banks
  • Road closures anticipated

Current:
Water levels on the Sydenham River and its tributaries are rising as a result of above normal temperatures and snow melt. Localized flooding is occurring at a handful of locations (Alvinston and Oil springs) while some areas have bank full conditions (Brigden and Florence).

In St. Clair Township, Pretty Road, South of Stanley Line is expected to be closed later today, due to flooding.

Short Term:
Precipitation forecast for today and tomorrow call for accumulations near 25 mm. Remaining snow will continue to melt with rain and above freezing temperatures. Water levels will remain high and near top of the bank on Sydenham River for the next few days. Drains and smaller watercourses in upstream areas may experience localized flooding in some areas.

Municipal officials and road superintendents should monitor local conditions.

Municipal emergency response staff and road superintendents should monitor local conditions closely.

Residents are reminded to avoid watercourses and flooded areas due to slippery banks, cold and swift moving water and deteriorating ice. Parents in particular are urged to keep their children away from floodplain areas.

The St. Clair Region Conservation Authority will monitor the flood condition of the watersheds in the region and will provide warnings to municipal officials and media in the event conditions develop which could result in the potential of flooding.

Update: As required.
