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.  

Severn 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. 


The KLCOA is an active member of the Coalition for Equitable Waterflow (CEWF).  The CEWF maintains an excellent website with considerable information regarding water levels on lakes feeding the Trent Severn Waterway (TSW).

Through this website the KLCOA endeavours to provide current and timely information regarding water levels for the Kennisis lakes.

Readers looking for historical information about water levels on our lakes or other lakes which feed the TSW are encouraged to use the links provided here to access the CEWF website.  The CEWF website also contains a wide variety of briefing notes, member communications reports and presentations regarding water levels and the related complex issues.  On the CEWF website the Kennisis lakes information can be found in reports for the Gull River area.  If you look at their historical data under the TSW Water Levels category you can access records detailing the average, minimum and maximum water levels for the Kennisis lakes going back to 1988.

In addition there are detailed reports for each of the five most recent years based on data provided by the TSW and Parks Canada.  For example, to see a water level chart for 2016, select the 2016 Water Levels Summary, click the link for Gull River and then scroll down to the Kennisis Lake graph. Here is the link to access the CEWF website CEWF.
