Significant rainfall has increased water levels and flows across the Trent-Severn.

Significant rainfall occurred over past 2 days and resulted in total precipitation over that time period of about 60-100 mm which increased water levels and flows across the system.  Some rainfall forecast is expected today  with a potential accumulation of 10-20 mm and higher in the areas of localized thunderstorm activity. 

Outlook

Due to the localized nature of the rain events some areas have received 150% of the normal monthly precipitation in September. 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.

Trent Severn Water Management team will be active, and the changing conditions will be closely monitored. Any watershed condition 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 above average. 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 Burnt River and Gull 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 level and are expected to increase across the system due to sustained and elevated inflows from the Haliburtons 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. Flows on the Trent River are above average and above normal for this time of year.

Severn River

Lake Simcoe water levels are above average, and expected to increase from resulted and the forecasted rain amounts. Black River flows are increasing as a result of the recent rain event. Lake Simcoe outflows are increased. Flows on the Severn River are increasing and are likely to remain high.
