SOUTH PORTLAND (WGME) — Hinckley Pond and Old Ice Pond in South Portland have been been closed to the public until the fall due to recent algal blooms that can kill dogs and make humans sick.
Blue-green algae is a type of photosynthesizing bacteria called cyanobacteria and exists in all Maine lakes. In lower concentrations, it is perfectly harmless. However, algal blooms can change that, as the resulting higher concentrations make the algae more toxic.
Experts say that eroding soil and dog waste are likely the biggest contributors. Both contain phosphorus that help algae grow.
Stormwater program coordinator, Fred Dillion states that : “Primarily just picking up after your dog would be really a big help and also trying to keep the dogs off the edge of the perimeter of the pond. keep them on the trails. which is really challenging, I know, because dogs like to go where they like to go”
Dillion also says the city will apply for grants to add more bushes and vegetation around the pond. That will help curb the erosion problem in the park.
The Maine DEP says if a pond or lake looks too green or cloudy, don’t go in. Other warning signs are if the water smells bad or you can see scum on the surface.
