Cultus Lake Aquatic Stewardship Strategy looks to science to guide its actions in protecting and preserving Cultus Lake.

CLASS also looks to traditional knowledge and stories from Sto:lo First Nations, including the Soowahlie First Nation, and other long-time residents to provide historical perspective and a base from which to measure changes in the lake and area. Much of the science comes via the researchers from the Department of Fisheries and Oceans research complex at Cultus Lake. Other information comes from other organizations with strong interest in the Cultus watershed, such as the Fraser Valley Salmon Table, the Chilliwack Museum, and the Fraser Valley Invasive Plant Council.

Over the years, CLASS members have built up their understanding of the underlying science required in order for the community and local governing bodies to take positive to protect the lake and watershed.

To date, one of the largest projects in which CLASS has been involved, by helping to secure funding and bringing partners together, has been the two-year study that looked at the nutrient overloading (Eutrophication) in Cultus Lake, completed in 2014.

Currently, CLASS was influential in supporting a Eurasian Watermilfoil management pilot project, which is being guided by its members with the Cultus Lake Park Board and DFO advisors. CLASS’ hydroacoustic software is an important tool for the pilot proponents as they set up the pilot study. (Watch for a report/plan released by CLASS in the fall.)
