Researchers from the University of Waterloo’s Department of Biology have been studying the water quality of Southampton’s Fairy Lake.
They say coarse sediments from nearby storm drains are seeping into the lake and affecting water quality, according to initial findings from their multi-year study into the health of the lake.
Led by Dr. Rebecca Rooney and Dr. Heidi Swanson, the team detected the presence of bacteria, possibly road salt, and most likely phosphorous and nitrogen contaminating the water
The researchers also found a higher-than-normal pH level in the lake, as well as evidence of contamination that could be due to goose or dog feces.
“The town used to have feeding stations for geese there, but those have been removed. But I think people are still heading down there and throwing breadcrumbs and whatnot for the geese. That’s really not a good idea because feces is ending up in the water and creating problems.”
The work is continuing this summer and beyond, but the research findings so far show that some invasive species like the Curly-leaf Pondweed is oxygenating the water and providing fish habitat, though it does present a danger to other area lakes if not carefully managed.
At this time, researchers presented the following recommendations on improving the health of Fairy Lake:
-Focus on water quality at the source by integrating a treatment wetland with settling basin to help treat stormwater before it enters the lake, in regard to existing and future developments
-Stop feeding geese in and around the lake
-Soften and naturalize the shoreline along High Street using native grasses, which helps deter geese and benefits other birds
-Post ‘stop the spread’ signage to help contain the Curly-leaf Pondweed and consider building a gear cleaning station so boaters can remove vegetation from their boats before and after using in the lake
“Part of the Town’s mission is to protect its natural resources and assets in a sustainable manner. We look forward to receiving the recommendations and considering them as part of our future capital plans,” added Charbonneau.
The project team will host a public information session in the coming months, inviting anyone interested in Fairy Lake to hear from researchers and learn more about the project.
