[3][4] In 2008, regional councillors asked the Commission de toponymie du Québec to rename Richmond Gulf as Lac Tasiujaq.

[6] On the south shore, there are the remnants of an abandoned Hudson's Bay Company trading post, called Fort Richmond, which operated from 1750 to 1759 and from 1921 to 1927.

[9] The western shore is guarded by the steep ramparts of sedimentary rock that rise abruptly out of the brackish waters.

The eastern shore rises more gradually and is largely Canadian Shield rock, overlain in many places by basalt.

Point Pamiallualuk is a narrow spur of rock that juts out some 2 km into Hudson Bay, just north of Le Goulet.

Here, the north-flowing tidal current of Hudson Bay collides with weaker counter-current to produce a lot of agitation, which is further enhanced by the strong wind.

[11] The many rivers flowing into Lake Tasiujaq make its water brackish but a healthy habitat for brook trout and whitefish, beluga and seal.

[7] Many species of birds, such as common loons, eider ducks and peregrine falcons, find summer shelter and nest here.
