Water Level Update

CEWF Update: Coalition for Equitable Water Flow
May 10, 2018

From the TSW:

Parks Canada’s water management team continues to actively monitor water levels and flows, and weather forecasts across the Trent-Severn Waterway. These factors are used to determine dam operations on a daily basis for the Trent-Severn Waterway.


The weather forecast indicates no rain for the next 5 days.


In response to very warm temperatures and no precipitation the inflows are rapidly receding across the system.

The Trent Severn Water Management team will be actively monitoring the changing conditions. Any watershed condition updates will be released by your Conservation Authority or local Ontario Ministry of Natural Resources district.

Haliburton and Northern Areas

Following the peak in freshet, the inflows to the lakes ceased at a very rapid rate due to higher than normal air temperatures and a dramatic reduction in the forecasted rain. Considering the high uncertainty in the forecast operations are being conducted to reduce the outflows from the lakes. Currently, most lakes on the Gull and Burnt River systems as well as the Central Lakes are leveling off or increasing as a result of the outflows reductions from operational adjustments. (As of May 12th the water level at the Kennisis Dam has leveled off at a point slightly below the historical average for this date.)

Kawartha Lakes and the Otonabee River

Rice Lake water level is declining. Flows on the Lower Trent River are declining.

Rice Lake and the Lower Trent

Rice Lake water level is leveling off. Flows on the Lower Trent River are decreasing as the Crowe River is receding.

Severn River

Lake Simcoe water levels are above average, above rule curve and declining. Lake Simcoe outflows remain maximized as Black River flows continue to decline. Flows on the Severn River are stable and decreasing.
