How contaminated runoff harms pets and wildlife
High algal blooms (HABs) are unsightly on the surface but cause great damage to Ringwood’s lakes—as well as to aquatic wildlife and plants, and our pets.
The toxins generated from HABs deplete the oxygen in the water, which essentially chokes the fish and leads to fish kills. They may also inhibit grazing activities of tiny plankton and reduce the growth and reproduction of these tiny aquatic communities. These toxins also block the sunlight that underwater plants need for photosynthesis, which causes the aquatic plant life to die as well.
No Pets Allowed!
Many dog owners enjoy tossing sticks into the lakes for their dogs to fetch. And many dogs love to plunge in to cool off in the lake on a hot summer day. During periods of high algae bloom, this is quite dangerous for our pets as well as area wildlife that lives near or relies on lake water.
After all, while humans can see these blooms and read signs warning them not to enter the water, our pets and wildlife cannot make that judgment call. When the lake water is dangerous for us to be in, it’s crucial to also keep our pets out. Pets and the many deer, rabbits, raccoons and other animals in our town can be poisoned through drinking or swimming in toxin-contaminated water.
