Description

In 2023, the DEQ listed sections of the Gallatin River as impaired due to recurring algal blooms. The blooms choke out fish and degrade water quality. State scientists are amid a six-year study trying to understand what's causing the harmful blooms. The state says it will use the results to inform local development regulations and a plan to protect the river.
