註釋
Trout biomasses and selected physical parameters associated with 5 types of habitat improvement structures were measured in a secion of the Boulder River near Basin, Montana in 1987-1989. The high relative attraction to salmonids, relatively low construction cost, and high physical durability indicate that check dams were the most advantageous form of habitat improvement structure.
