The square-foot bottom sampler has been the principle instrument used for quantitative studies of the bottom fauna in riffle areas of streams. However little has been written concerning the actual number of square-foot samples necessary to describe stream bottom fauna in terms of the number or volume of organisms. The object of this study is to determine the minimum number of bottom samples that adequately describe the bottom at any time or location. The study areas are located in Logan River, Utah, and two of its tributaries: Temple Fork and Beaver Creek.
