A quantitative study of the bottom fauna in some Utah Streams Variously Affected by Erosion

Floods and cloudbursts in the Intermountain region of western United States cause considerable damage to watersheds and streams. Because of steep gradients these torrential waters remove vast quantities of debris, stones, gravel and soil from the stream beds. It follows that, with the removal of materials from a stream bottom, the flora and fauna would also be affected. To determine the effects of flood conditions upon bottom fauna and the subsequent reestablishment of these forms is the purpose of this study.
