Water Level Management Update – Wednesday, December 19, 2018



The weather forecast for Thursday and Friday of this week suggests a precipitation event in the amount of 30 to 50 mm.


Depending on the amounts of rain across the areas local snow melt and snow melt runoff will occur greatly impacting the watershed response. Water levels and outflows are expected to increase at all locations due to the precipitation. Trent Severn Water Management team will be active and the changing conditions will be closely monitored. Any watershed conditions updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.
