Watershed conditions - water safety

The Lake Simcoe Region Conservation Authority advises that the water levels in Lake Simcoe continue to be higher than average for this time of year. These higher than average water levels are posing a risk of flooding along the Lake Simcoe shoreline.  

The above average water levels in Lake Simcoe are expected to remain high in response to the precipitation and inflows from rivers and streams within the system. 

This week, the water levels in the lake have increased from 219.18 metres (measured on April 15, 2024) to 219.21 metres (measured on April 19, 2024).  Currently the lake level is approximately 15 centimetres higher than average for this time of year and is increasing at the rate of approximately 0.5 centimetres per day. 

Based on current weather forecasts, lake levels are anticipated to reach their peak by early to mid next week with the water level potentially reaching 219.30 metres.  Depending on the precipitation received in the coming days, the water levels may start to stabilize next week. However, this is subject to change based on weather forecasts.   

The current wind forecast indicates westerly winds today in a range of 30 km/hr with the wind gusts up to 50 km/hr. The forecast for the next few days ranges from 30 km/hr winds with gusts of up to 40 km/hr.   

There is the risk of flooding adjacent to the lake in low-lying areas due to impacts of wind and wave action and continued flows in the system.

This Shoreline Hazard Watch will be in effect through Thursday, April 25, 2024.
