On August 31, 2014 the KLCOA unanimously passed the following motions regarding By-law Variances and Environmental Protection: Municiple Bylaw and Environmental Protection



Dam Replacement Update

April 2017: The dam replacement is complete. Remediation of the lakeside boat launch area and adjustments to the roller ramp were completed over the winter. 

Previous Posts and Background:

December 7, 2016: The dam replacement is complete. Remediation of the lakeside boat launch area and adjustments to the roller ramp are scheduled for December 7, 2016. 

August 5, 2016: The dam is complete. Landscaping has been done. However, there is work outstanding on the roller ramp and the lakeside boat launch area.

On November 30, 2014 Parks Canada provided an update on the proposed Kennisis dam replacement project.

As of August 26, 2015 work had begun as per the planned schedule. The contractor selected by Parks Canada is Ross & Anglin Ltd. 

On December 9, 2015 a further update was received from Parks Canada confirming that the project remains on schedule for substantial completion in Spring 2016.

February 16, 2016: The new dam has been commissioned. Decommissioning of the diversion channel is due to be completed by early March. Final landscaping is scheduled for April. The TSW provided the attached image of the new dam as of early February 2016.

May 21, 2016 update to posting of May 13, 2016: The work begun on May 16th will continue during the week of May 24th. An updated Information Bulletin was issued on May 20th. On May 21st the TSW make a presentation to the KLCOA at the Spring General Meeting.

May 13, 2016: Starting May 16th landscaping, site remediation plus some additional concrete and sheet-piling work  is scheduled to be completed on the dam. Parks Canada has provided an Information Bulletin explaining some of the details. 

June 17, 2016: The dam is complete. Landscaping has been done. However, while the the roller ramp is in place, it is not secure and will not be ready for use until about the end go June. 





Information on other TSW capital projects was provided by CEWF in February 2016.

An agreement has been reached with the Municipality of Dysart et al for the use of property on the north side of the dam to facilitate construction. The KLCOA has been advised that the construction should be substantially complete within 6 months, with tree-planting and other seasonal activities deferred until spring of 2016. During construction a temporary portage route will be maintained around the dam: the roller ramp will not be accessible but will be reinstalled after construction. Road access and use of the vehicle ramp/boat launch will be maintained until November 17, 2015 for those heading down the Kennisis River to Red Pine Lake. Thereafter it will be closed until ice-out in 2016. Construction activities are not expected to affect the normal seasonal water level fluctuation. Parks Canada has committed to proving KLCOA with regular updates as the project progresses but notes that all, as with any construction project, dates are subject to change depending on circumstances.




Water Level Update

June 22, 2017: The Kennisis Lakes remain 100% full due to the wet spring weather, which has left the entire watershed saturated and Lake Ontario at an all time high. The TSW’s goal is to restore normal seasonal levels in all parts of the TSW system as soon as possible while continuing to manage water levels so as to mitigate flooding and to ensure safe navigation.

May 18, 2017: Since the extreme high water level at the beginning of May, the lake has been steadily dropping about one inch every two days. Currently it is 4" above the 100% full mark.

The cause of the high water levels is rain! During the week beginning on April 30th the Kennisis Lake weather station recorded 108mm of rain. The monthly average for all of April is 73mm. This rain was part of a widespread regional weather system that led to severe flooding throughout parts of Ontario and Quebec. The Toronto Islands are flooded, so is Wolfe Island near Kingston, so are parts of Prince Edward County. Lake Ontario is at a record high and will take a long time to come back down due to the flood risk in Montreal.

The entire Trent basin is dealing with high water levels and high flow rates. The TSW has postponed the traditional Victoria Day weekend opening of the Trent-Severn Waterway by at least a week due to unsafe navigation conditions.

For Kennisis Lake there has simply been more rain that the system can handle. Under normal conditions the lake level can be held steady if there is less than about 40mm of rain over a 7 day period. When three times that amout of rain falls in a single week then the lake will rise. Due to runoff from the surrounding land, one inch of rain falling on the lake can easily translate into a 3-4 inch rise in water levels. 

The chart below shows the 2017 water level (blue line) close to the multi-year average high (red line) at the start of the year, before rising dramatically in late April. This is in contrast to the high water levels experienced early in 2016 (second chart below) and the low water levels experienced in 2015 (third chart below). 











[Previous post: May 2, 2017: The ice went out on April 18th. On April 30 & May 1 a total of 65mm (2.5") of rain caused the lake to rise significantly. It is now 7" over the top of the dam just shy of the 100-year record experienced in 2016 (NOTE: The 30-year extreme levels on the TSW chart do not yet include the 2016 data).]

To see a water level chart for 2013 go to Water Levels 2013. For 2014 go to Water Levels 2014. For an update on the dam go to Kennisis Dam.
