The American eel population has experienced a marked population decline. Habitat loss resulting from dam construction to improve the control and use of freshwater discharge is one of the factors involved. There are some 5600 dams in rivers draining to the St. Lawrence in Quebec. Their passability to eels migrating upstream and downstream has been assessed using the dams database of the Centre d’expertise hydrique du Québec. Softcover 11-10 2011-03-11 Tremblay, V.
