The Atlantic Whitefish has adapted to a completely freshwater habitat in lakes within the Petite Riviere watershed. The area around the Petite Riviere was first settled in the 1600s and the subsequent building of mill dams along the river was extensive (Dunfield 1985). While these mill dams would have obstructed the river to varying degrees, the construction of a hydro-electric dam at the foot of Hebb Lake as early as 1901 effectively blocked any upstream migration of fishes. There is no record of fish ladders or any.
