Watershed Conditions Statement - Flood Safety
Issued January 11, 2018
Flood Potential: Low
The Ganaraska Region Conservation Authority advises that a messy winter storm will move into southern Ontario this evening bringing mild temperatures and rainfall followed by plunging temperatures beginning tomorrow afternoon. The forecasted rainfall amounts are 15 to 25 mm. The rain is expected to begin with scattered light showers during the day and become more steady rainfall this evening and overnight.
The forecasted rainfall, mild temperatures and melting snow will contribute runoff causing water levels and flows in local streams to rise. There is potential for ice-break up and subsequent ice jams. All water bodies, including ponds, streams and many ditches will be flowing higher than normal. No flooding is anticipated at this time.
Additionally, slippery stream banks, unstable ice cover, and fast flowing, cold water will create hazardous conditions around all bodies of water. As a result, local streams and rivers will 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 Friday January 12th, 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.
