Flood Potential: Low
The Ganaraska Region Conservation Authority advises that a low pressure system is moving into Southern Ontario this evening. Rain is expected to start overnight with total rainfall amounts of 20 to 30mm, which will taper off by morning as the storm moves out of the region.
The watersheds are generally saturated with reduced storage in wetlands due to the storm last Saturday. There is still a snowpack in headwater areas of the watersheds. This snowpack is very dense from absorbing rainfall from previous storms and will likely add runoff as it continues to melt.
The forecasted rainfall combined with melting snow and saturated ground conditions will result in higher than normal water levels and flows in all our local streams. No flooding is anticipated.
Additionally, slippery stream banks, and fast flowing, cold water will create hazardous conditions around bodies of water, 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 Thursday, March 2nd, 2017. 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.
