The 1913 Regional Map of the North Shore of the Gulf of St. Lawrence named it "Piashtibaie River".

Three miles from its mouth, says surveyor H. H. Robertson (1889), there are falls of 150 feet surrounded by fairly good woods.

The Piasthi-Baie post, which dates back to 1862, includes a dozen families who live off the cod and lobster fishery.

[5]Map of the ecological regions of Quebec shows the river in sub-regions 6j-T and 6m-T of the east spruce/moss subdomain.

A banding station for migratory birds operated at Lake Salé until 2004, and held the record for the highest concentration of green-winged teal (Anas carolinensis) in North America.

Birds of prey include the merlin (Falco columbarius) and bald eagle (Haliaeetus leucocephalus).

In view of the rapidly declining Atlantic salmon population catch-and-release should have been implemented on all rivers apart from northern Quebec.
