It covers an area of approximately 20 square miles and is known for its rich biodiversity, including various fish species and bird populations. The bay is a popular destination for recreational activities such as fishing, boating, and birdwatching. The bay is also significant for its historical and cultural importance. It has been a site for Indigenous peoples for thousands of years and played a role in early European exploration. Today, Missisquoi Bay is part of the Missisquoi National Wildlife Refuge, which aims to protect its unique ecosystems and wildlife habitats.
