The river supports a variety of fish species, including Atlantic salmon, striped bass, and American shad, and is an important migratory corridor. Downstream, the river enters Merrymeeting Bay, a unique tidal freshwater ecosystem that provides critical habitat for waterfowl and aquatic life. The plant's discharge must meet state and federal water quality standards to protect these downstream environments.
