Carleton University Launches Comprehensive Study on Dow's Lake Swimming Perceptions
The National Capital Commission created significant community interest last summer when they officially opened Dow's Lake for swimming in June 2025. This initiative featured a newly installed recreational dock with buoy lines, marking a dramatic transformation for a water body once considered too contaminated for recreational use.
Academic Partnership Seeks Community Feedback
In collaboration with the NCC, Carleton University researchers launched a detailed survey during the winter months to gather perspectives from residents who either swam in the lake last summer or plan to do so in the future. Professor Sean Landsman, who helped develop the survey instrument, is currently analyzing preliminary results that reveal a fascinating spectrum of community attitudes.
"The responses range from enthusiastic declarations like 'I've been waiting for this for so long' to more cautious statements such as 'I wanted to prove to people that you can swim in Dow's Lake and be totally fine,'" Landsman explained. "This diversity of opinion speaks directly to the lingering hesitation some community members still feel about water quality in urban environments."
Historical Perceptions Versus Current Reality
Despite the NCC's water testing in 2025 confirming that the swimming area consistently met or exceeded all applicable health and safety guidelines, online discussions revealed persistent concerns. When a Reddit user posted about the new swimming opportunity in June 2025, comments ranged from enthusiastic support to expressions of disgust, with one user describing the water as "gross" and "stagnant."
Professor Banu Ormeci, whose research focuses specifically on water and wastewater treatment, attributes these concerns to outdated perceptions from previous decades. "We conducted extensive water sampling at five different locations over three months, testing more samples than even Ottawa Public Health," Ormeci stated. "The water quality is excellent, with no concerns about E. coli limits being exceeded in the river system."
The Concept of Swimmable Cities and Blue Spaces
Landsman emphasizes that this project revolves around the emerging concept of "swimmable cities" and the importance of "blue spaces" in urban environments. "When we think of green spaces, we typically imagine parks and forests," he noted. "But blue spaces focus specifically on water features and their recreational potential within city landscapes."
Dow's Lake represents one of Ottawa's primary blue spaces, and the NCC partnership provides researchers with a unique opportunity to understand how more residents can be encouraged to enjoy waterfront activities. "There's increasing emphasis on expanding beyond our successful green space initiatives to develop our blue spaces in similar ways," Landsman observed.
Building Community Stewardship Through Recreation
The research team hopes their findings will demonstrate how recreational access can foster greater environmental stewardship. "When people can safely swim and recreate in urban blue spaces, they develop stronger connections to these environments," Landsman explained. "Those enjoying these spaces become more invested in their protection and maintenance, creating a positive snowball effect for environmental conservation."
The study represents a significant academic contribution to understanding how urban water bodies can be transformed from perceived hazards into community assets. As Ottawa continues to develop its waterfront recreational opportunities, this Carleton University research will provide valuable insights into public perceptions, water quality management, and the social dimensions of urban swimming initiatives.
