A STUDY OF THE EFFECTS OF STREAM CHANNELIZATION AND BANK STABILIZATION ON WARMWATER SPORT FISH IN IOWA: SUBPROJECT NUMBER 2. A STUDY OF THE IMPACT OF SELECTED BANK STABILIZATION STRUCTURES ON GAME FISH AND ASSOCIATED ORGANISMS
Four types of bank stabilization structures installed mainly for highway protection--revetments, retards, permeable jetties, and impermeable jetties--were studied during the summer and fall of 1974 to determine their impact upon game fish habitat in Iowa streams. Stream width, depth, current velocity, water temperature, and turbidity were measured. Permeable jetties and retards deepened the channel near the structures. No other significant differences in physical parameters between structured and non-structured sections of stream were found.
