It serves as a vital ecosystem, supporting a variety of marine life and providing opportunities for recreational activities such as sailing and fishing.

The lake is recognized for its historical and cultural significance, being of importance to the Mi'kmaq people and having a rich history that includes European exploration. The geography of Cape Breton Island, characterized by its stunning landscapes, is integral to understanding the importance of this lake which dominates the island’s central region.
