Aquatic Invasive Species

What are Aquatic Invasive Species?

Aquatic Invasive Species are plants and animals (mussels) that can infest our lake, damage pumps and irrigation systems, and clog boat props. 

Once established, aquatic invasive species are almost impossible to remove. 

What you can do to protect Chestermere Lake:

If you want to launch a boat that has been in any body of water outside of Alberta:
  • Clean: Always clean, drain, and dry your boat and all recreational gear.
  • Dry: Keep the boat out of the water for at least 30 days to ensure no mussels have survived.
  • Inspect: If it has not been out of the water for more than 30 days, have your boat inspected. Call Toll Free: 1 855 336-2628 (BOAT) for the nearest inspection site.

Flowering Rush Research Update

small imageResearchers from the Alberta Government were out establishing plots and speaking with homeowners. Residents are asked to avoid areas around the plots to minimize disturbances. All plot markers will be removed after the water is drained from the lake, sometime after Thanksgiving.

Diver assisted
Suction Harvesting (to remove Flowering Rush) is planned to begin in the south portion of the lake on Aug 21 and is expected to take approximately 5 days to complete the removal. Boaters, please avoid the south end bay and if you see the divers give them space to work. 

If you see any Flowering Rush in the lake, do not remove or touch it as disturbing it can cause it to spread more easily. Learn more about Ms. Kimmel's Research here.

flowering rush

Flowering Rush is an ornamental plant that can grow completely or partially submerged along the shoreline. Flowering rush may pose a serious threat by reducing the water quality and availability for native vegetation and wildlife. Under the Alberta Weed Control Act and the Alberta Fisheries Act, flowering rush is listed as prohibited meaning it must be eradicated when found. Once established, this species is extremely difficult to control. 

The City of Chestermere is pleased to collaborate with Alberta 
Agriculture & Forestry to better understand aquatic invasive species and the best methods to eradicate them. Ms. Nicole Kimmel will be in Chestermere throughout the summer conducting a research project on Flowering Rush. If you see any of these plants, do not remove or touch them as disturbing them can cause them to spread more easily. Learn more about Ms. Kimmel's Research here.
