Chedoke Creek Remediation Update: Implementation of small-scale works in Chedoke Creek and Princess Point

HAMILTON, ON – On June 11, 2021, The City received Ministry of the Environment, Conservation & Parks (MECP) approval for the Chedoke Creek Workplan and Cootes Paradise Report. As part of the approval of the workplan, the City is required to implement short-term direct measures in areas around lower Chedoke Creek and Princess Point and has since completed work on two small-scale projects.

Small-scale aeration system

On Wednesday, September 8, a small-scale aeration system was installed close to the Kay Drage Park bridge. The aeration system will help circulate and increase oxygen levels in the water which will help decrease the amount of excess nutrients that contribute to algae blooms and cloudy water.

Floating treatment wetlands

On Saturday, September 18, crews completed the installation of an 800 sq. ft. floating treatment wetlands just inside the Princess Point Embayment. The plant roots installed will remove nutrients from the water such as Phosphorus and Nitrogen and create an ideal habitat for a diversity of plant, animal and microbial life.

In the coming weeks, signage will be installed near the Kay Drage Park bridge and Princess Point Embayment to educate visitors about both of these projects.

Both small-scale projects will be evaluated for long-term effectiveness before being considered as potential solutions within the Cootes Paradise Workplan. If advanced, a much larger version of each would be deployed as part of the Cootes Paradise Workplan.
