Flood Status

September 7 2018 - The Ganaraska Region Conservation Authority advises that remnants of Hurricane Gordon will move through the watershed starting Sunday night. Rainfall in the amount of 50 to 60 mm is forecast for Sunday overnight and into Monday.

Local rivers and creeks are currently flowing at normal summer levels. Ground conditions are generally dry and should help to absorb some of the rainfall.

The forecasted rainfall will cause water levels and flows in local streams to rise especially after the heavier rainfall on early Monday morning. Should these rainfall totals materialize, minor flooding in low lying areas adjacent to streams is possible on Monday morning. All water bodies, including ponds, streams and many ditches will be flowing higher than normal.

Additionally, slippery stream banks and fast flowing water will create hazardous conditions around all bodies of water. As a result, local streams and rivers may become dangerous, especially in the vicinity of culverts and bridges. Children should be warned to stay away from all watercourses.

This Watershed Conditions Statement will be in effect through Tuesday September 11th, 2018. Conservation Authority staff will continue to monitor watershed conditions and provide updates as necessary. Should you have any questions or wish to report flooding, please contact the following GRCA staff at 905-885-8173.

Note: A Watershed Condition Statement for Flood Outlook is issued as notice of the potential for flooding based on weather forecasts calling for heavy rain, snow melt, high wind or other conditions that could lead to high runoff, cause ice jams, lakeshore flooding or erosion.
