TSW Water Management Update



The five-day weather forecast predicts a low system that may result in 30-40 mm of rain and heavier amounts in localized areas impacted by thunderstorms.


During the last three weeks, the Trent-Severn watersheds have received close to 100 mm the above-normal amount of rain. Due to the localized nature of the rain events, some areas have received twice the monthly precipitation.  The impacts from the above-average amounts of precipitation received remain across the system.  Flows and levels are above normal for this time of the year across all locations.   

Given the amount of rain in the short-term forecast, the 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. 

Haliburton and Northern Areas 

Water levels and flows remain high in northern areas. Most lake levels on the Gull River, Burnt River system and Central Lakes are near full and are increasing. Lake levels are monitored on a 24-hour basis, and water management operations are being conducted based on the current watershed conditions, lake levels, estimated runoff amounts and forecasted rainfall. The flows on the Burnt River are above average and increasing and are expected to be sustained by the enhanced runoff from precipitation and operations in reservoirs.  The flows on the Gull River are above average for this time of year. 

Kawartha Lakes and the Otonabee River

Water levels in the Kawartha Lakes are above full, and the conditions across the system are due to sustained and elevated inflows from the Haliburton areas and the received amounts of rainfall. Flows on the Otonabee River are above average for this time of year. 

Rice Lake and the Lower Trent

Water levels on Rice Lake, Upper and the Lower Trent River are above average for this time of year. The Crowe River has peaked and is receding.
