A shutdown of Brookfield’s McKay Hydro-electric Station below Ripogenus Dam occurred on July 7, 2023, leaving the West Branch of the Penobscot River virtually dry for over 4 hours and unquestionably resulting in devastating impacts to fish and aquatic communities, harming the river system, and impacting boating and recreational activities.
“The photos of the Big Eddy taken the evening of July 7 show water levels lower than I have ever seen them, and the waters may have continued to drop as the outage persisted,” said Ed Spear, retired fisheries biologist formerly employed by Great Northern Paper, an owner of the Ripogenus Dam before Brookfield. Spear went on to say: “Essentially, the entire West Branch 2023 salmon year class was eliminated. The timing of this disastrous outage could not be worse as it occurred during the peak fish and aquatic growing season and a prime angling period and it occurred during daylight hours. Recently emerged alevin (larval salmon) are extremely vulnerable to rapid flow change and the initial dewatering and subsequent flooding of the riverbed. The Holbrook Spawning, Incubation, and Nursery Channel (FERC License Article 406) would have been completely dewatered during the event on July 7.”
