Lake sturgeon, present in half the watersheds, lives in lowland rivers and large lakes. Its range seems secure in the Saint Lawrence drainage where it is found in the main channel of the Saint Lawrence River, Lake Champlain and downstream of the lowest barrier in tributaries. Its abundance has not recovered from 19th century declines. Lower reaches of the Oswegatchie, Grasse, Raquette and Oswego rivers provide spawning habitat. Stocking since 1995 has rebuilt a population in the Oswego watershed and juveniles have entered the upper Mohawk watershed, where this species is not native. It has been classified as Threatened, but recovery programs accompanied with numerous spawning events suggest that its status needs to be reconsidered.
