Abstract

Alterations of streams to facilitate highway construction and consumptive water use has become a fisheries management problem. To evaluate the effects of channeling concomitant to construction of Interstate 80 N. near Henefer, Utah, altered and unaltered sections of the Weber River were compared on the basis of fishes censused, population estimates and ordinations. Species compositions in particular areas were influenced by local rheologic conditions. Changes in species composition between samplings at a particular area were caused by fish movements. Data from altered sections, rehabilitated with deflectors and checkdams, were not noticeably different than data from unaltered areas. However, fish movements indicated an unstable environment throughout the study area. This shows that it may be possible to restore channeled streams to productive fisheries.
