Its salmon stocks are in great shape and people pay big money for permits to fish there. Hoagy Bix Carmichael, son of the singer-songwriter of the same name, fell in love with the Cascapedia River. Carmichael took producer Bob Carty fly fishing and talked about the river’s unusual history and of concerns for its future.
