Maitland Conservation is issuing a Watershed Conditions Statement – Water Safety for all municipalities in the Maitland and Nine Mile River watersheds.
A Texas Low will track through the Great Lakes region on Thursday, bringing unseasonably warm temperatures, strong winds and upwards of 25 mm of rain to the Maitland and Nine Mile River watersheds. Showers are forecasted to begin early Thursday and intensify throughout the morning hours before tapering off to steady light rain in the evening. Precipitation is expected to shift to light snow as temperatures drop below 0°C overnight. The brief period of intense rainfall Thursday morning will be accompanied by mild temperatures that will approach 9°C, causing rapid snowmelt and a quick runoff.
Significant flooding is not expected at this time. Levels in watercourses may approach bankfull conditions resulting in minor ponding in typical low-lying areas. Smaller streams in headwater areas are expected to quickly peak by Friday, while larger rivers will peak over the weekend. River ice will weaken and breakup as water levels rise throughout the watershed. Minor ice jamming remains a possibility but is not expected.
Municipal officials are encouraged to check drainage systems and monitor low-lying and flood prone roads. We remind people that slippery and unstable streambanks and cold-water temperatures will create hazardous conditions around all watercourses. River ice will be extremely unstable and dangerous.
Maitland Conservation is monitoring watershed conditions and will provide an update if warranted.
This message is in effect until the afternoon of Monday February 13, 2023.
