-Blooms have been detected below advisory levels, but conditions can worsen with warm weather before official updates are posted. Dogs are more vulnerable than humans, so we recommend they avoid swimming.
If you look across a body of water and there appears to be pea-green slime, bright-colored “moss”, or bright green circles across the surface, this is toxic algae. If it is windy, the algae blooms may have been temporarily pushed to the shoreline; however, this doesn’t mean that the water is safe to swim in or drink. These blooms can kill your pet!
