— 1 min read

The Glendale Hydroelectric Project, operated by Hitchcock Hydro, LLC, a subsidiary of Relevate Power, LLC, has submitted the 2024 Invasive Species Monitoring Report to the Federal Energy Regulatory Commission (FERC) as required by the project's license. The report presents the findings of a detailed assessment of invasive species within the project boundary, using a repeatable methodology to compare results across years. The survey identified one new aquatic plant species, water chestnut (Trapa natans), which was not previously observed, and hand-pulling of the species was conducted in consultation with relevant resource agencies.
