News Release

Hebgen Lake Toxic Algal Bloom

The Gallatin City-County Health Department (GCCHD) was notified Wednesday by Northwestern Energy that routine monitoring of Hebgen Lake has confirmed the presence of a toxic algal bloom in the lake. The algal bloom is occurring along the north shore of the lake and may appear as green or turquoise colored scum on the surface of the lake. Death of domestic animals has been attributed to ingestion of water during toxic algal blooms at Hebgen Lake in the past.

The identified algal toxin poses a threat to people, pets and livestock. Ingestion or prolonged contact with the algal bloom may result in illness, with signs such as muscle twitching, staggering, convulsions, paralysis and death. Livestock that drink large amounts of contaminated water and pets that collect scum on their fur then ingest it by licking are at highest risk from toxin exposure. Toxin exposure can occur in humans from recreational activities where water might be ingested such as swimming, wind surfing, jet skiing, and water skiing. Read more here.
