Receding water levels a concern for Gull Lake, Alta.

Residents of Gull Lake, Alta., are concerned about drastically receding water levels and are trying to come up with creative solutions to refill the popular lake. Keith Nesbitt has lived in Gull Lake since 2007 but has been coming to the lake recreationally since the ’80s. As a director with the lake’s watershed society, he’s concerned about how much the water levels have dropped this year. “You can look at the beach here and you can see what’s happened to it. The boats are out even further. It’s getting critical, we have to do something with the lake,” he said.

Harmful algal blooms work by disrupting food webs, Dr Caron said. Creatures such as shellfish, anchovies and sardines consume the toxins before then being eaten by larger marine mammals. "They eat a meal of those highly toxic fish and then they become toxified themselves, and if they get enough of that material, it of course can kill them, which is happening now," he said.
