Harmful Algal Blooms

In late June 2022, several dogs became sick and one died after swimming and consuming a lot of water at Jordan Lake. After testing for harmful algae blooms, no cyanotoxins were present. However, we will begin monitoring at several Swim Guide locations throughout the summer months for cyanobacteria and the toxins these blooms can produce.
