Unsafe Water Report Issued For This Popular Montana Swimming Spot

Harmful algal blooms (HABs) are present at the boat launch area at Hyalite Reservoir and at the Elk Grove Park Pond in the Elk Grove subdivision south of Four Corners. Ingestion or prolonged contact with the algal bloom may result in illness, with signs such as muscle twitching, staggering, convulsions, paralysis and death. Importantly, children and pets are more likely to ingest HAB infested waters because they spend most of their time wading in the shallow waters where algae can accumulate, and they have less control over how much water they ingest. We encourage recreationists to exercise caution to avoid an algal bloom that could potentially produce toxins that pose a risk to people, pets, and livestock.- Gallatin County Health Department
