Have you ever wondered what is happening beneath the ice on a frozen lake? How do fish and other organisms survive for so long beneath the frozen surface? Let's back up just a bit to talk about what happens before the lake freezes. During the summer, most lakes are thermally stratified. Warm lower density water sits on top of colder higher density water. As summer transitions to fall, the upper layers cool, breaking down that density difference. Eventually, the surface of the lake cools to 4 degrees Celsius (39.2 degrees Fahrenheit), the temperature at which water is most dense. This causes…

Ultraviolet light has been used for many decades as a non-polluting, highly effective disinfection technology that is deployed in a wide variety of disinfection applications including indoor air disinfection. The CDC recommends a layered approach to reducing the spread of pathogens including improved ventilation. As part of an improved ventilation program, UV can offer benefits by attacking and reducing aerosol pathogens as and where they are generated. The pandemic has revealed an inadequate plan of preparation across a wide swath of society. It is becoming apparent that staff and customers are expecting that service providers, professionals and other types of public-facing businesses…

Pond dyes can be used year-round. Blue dye in ponds is shown to not harm animals or floating and emergent plants in ponds. Many open bodies of water experience algal blooms during the spring and fall seasons when the weather changes. This flush of algal growth occurs when the seasonal winds and temperature changes stir the water, bringing up sediments from the bottom and creating an addition of fresh nutrients to the water. This turnover process is normal but can cause your lake or pond to turn green or brownish green during these times. This event is typically short-lived, and the water…

We all enjoy our province’s lakes, wetlands and their shores as they provide ample benefits and opportunities to play, relax, live and make a living. Lakes also act as a water source for some municipalities, agricultural producers and industries.

We are delighted to announce the launch of our new website!

New Website Coming Soon!
