Four projects to study docks, long-term lake change, microplastics and road salt in the Rideau Lakes
PORTLAND — The Rideau Lakes Environmental Foundation (RLEF) has announced the recipients of its 2026 Small Grants Program, supporting four research projects focused on environmental conditions in the Rideau Lakes.
The projects will examine dock design, long-term ecological change, microplastic contamination and the effects of road salt on aquatic life.
Dock design and lake ecosystems
A team from Carleton University, led by Dr. Steven J. Cooke, will study how different dock types affect nearshore ecosystems. The Rideau Lakes contain six common dock styles, including floating, cantilever and permanent structures.
Researchers will survey fish, invertebrates, birds and turtles in Big Rideau and Lower Rideau lakes. The study aims to provide evidence to guide lake associations and regulators on lower-impact dock design.
Tracking long-term lake change
Dr. John P. Smol of Queen’s University will expand ongoing paleoecological research into Rideau system lakes. Sediment analysis has already documented the effects of shoreline development, nutrient loading and climate-related changes.
The new work will include bottom-dwelling invertebrates in Lower Rideau Lake and zooplankton indicators across several lakes, including Big Rideau and Upper Rideau. The goal is to establish baseline conditions and better understand environmental change over time.
Measuring microplastics
Dr. Mehriban Jafarova of Trent University will conduct the first study measuring microplastics in the Rideau Lakes. Sampling will take place in Upper Rideau, Big Rideau and Lower Rideau lakes.
The research will analyze the type, size and distribution of plastic particles in water and sediment to identify sources and accumulation patterns.
Road salt and aquatic life
Graduate researchers from Queen’s University will examine how road salt affects zooplankton under different seasonal conditions. The study will test impacts during winter, summer and simulated heatwaves.
The research will assess how chloride levels influence aquatic food systems and inform decisions on de-icing practices.
The four projects were selected through RLEF’s annual Small Grants competition, which supports research on environmental conditions in the Rideau Lakes. The program also provides opportunities for graduate and undergraduate researchers.
RLEF president Jennifer Trant said the projects address questions relevant to residents and visitors and will contribute to long-term understanding of the lakes.
The foundation supports research, habitat protection and environmental monitoring across the Rideau Lakes. More information is available at www.rlef.ca.
