Belleisle Bay

Belleisle Bay is a fjord-like branch of the Saint John River in the Canadian province of New Brunswick.

Species of fish common to the area include, among others: The bay is oriented northeast from the river, which it joins at the head of Long Reach, just south of the village of Evandale.

Belleisle Bay forms part of the northern boundary of southern New Brunswick's "Kingston Peninsula", with the southern boundary being the Kennebecasis River.

Belleisle Bay has little current as it has few freshwater inlets and acts more-or-less as a lake in a glacial valley, framed by the low rolling hills of the St. Croix Highlands of the Appalachian range.

Although the bay is mostly freshwater, the entire lower Saint John River system has a limited saltwater tidal influence resulting from the Reversing Falls.
