Passage of adult Atlantic salmon in the Penobscot River, Maine
Atlantic salmon runs in the Penobscot and Kennebec Rivers of Maine are federally endangered and remain low. Inefficient fishways at dams continue to slow and prevent upstream migrations to spawning habitat, and delays of weeks to months are common. These delays expose fish to elevated water temperatures, resulting in increased metabolic demands.
