Management of Zebra Mussels in Clear Lake in Riding Mountain National Park

Riding Mountain National Park is proposing management actions to respond to the detection of Zebra Mussels (Dreissena polymorpha) in Clear Lake, located within the park boundaries. The management actions that may be implemented include the use of potash molluscicide and physical methods (e.g., benthic mats, manual removal, etc.). Zebra Mussels can impact native species, severely affect and/or alter food webs and ecosystems, damage infrastructure, and affect visitor experience. The proposal will be assessed using Parks Canada's Detailed Impact Assessment pathway.

Scope: The Detailed Impact Assessment will assess the impacts of management actions in response to the detection of Zebra Mussels on the Park's ecological integrity, cultural resources, species at risk, and visitor experience values. The valued components to be assessed include: values of importance to Indigenous communities as identified through consultation and engagement efforts, cultural resources, water quality, fish and fish habitat, non-target native freshwater mussels and aquatic invertebrates, terrestrial and aquatic bird species, vegetation, and visitor experience.
