Coalition demands action after thousands of fish found dead near Ripogenus Dam
A coalition, including the Maine Council of Trout Unlimited, demanded action after thousands of fish died near Ripogenus Dam in late July. The incident occurred due to a transmission line failure that caused a two-hour dam shutdown, significantly lowering water levels. The coalition claims the dam is outdated and poses risks to the ecosystem. Brookfield Renewable, which manages the dam, is awaiting relicensing for the project.
