Water Level Management Update – Jan 10, 2018
Varying amounts of rainfall ranging from 20 to 40 mm are forecasted for the 11th and 12 of January. The higher rainfall amounts are forecasted in the Haliburton and northern Black River area.
Water levels and flows are anticipated to increase at all locations. Trent Severn Water Management teams 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
All reservoir lakes are at their respective winter set dam configuration. Water levels on the reservoir lakes are near the long term average. The recent very cold weather has resulted in a gradual decline in river flows.
Kawartha Lakes and the Otonabee River
The Kawartha Lakes levels are in general below average and the drawdown is underway in preparation for the spring freshet. The Otonabee River flows are below average for this time of year.
Rice Lake and the Lower Trent
Rice Lake water level is near long term average as are flows on the Lower Trent River.
Lake Simcoe is tracking well to the target water level for this time of year. Flows on the Black River have been gradually receding with the cold weather. Flows on the Severn River are below average.
