To eliminate severe channel erosion caused by flooding, a dry floodwater-retarding structure (FRS) was installed in 1964 on Trout Creek in southwestern Wisconsin. Because this FRS was built at a valley constriction that was also a prime spawning area for wild brown trout (Salmo trutta), a study was initiated on the impacts of the FRS on the trout population. These impacts were determined primarily through comparison of trout population response upstream from the FRS with that downstream during 16 years after construction of the FRS (1964-79), but also through comparison of some preconstruction data on trout populations (1960-64) with the postconstruction data.
