Colinet is an incorporated town located on the northwest arm of St. Mary's Bay in Newfoundland and Labrador, Canada.

The Rocky River has a man-made salmon ladder spanning the 8 metres (26 ft) waterfalls at its mouth.

Originally not a salmon river because of those falls, the river was seeded with salmon fry in the mid-1980s.

The salmon began using the man-made ladder to bypass the falls in 1987.

In 2002, the river opened to recreational anglers, making it Atlantic Canada's newest salmon river.
