The authors observed the use of brook trout (Salvelinus fontinalis) as indicators of changes in water quality and stream characteristics, on a section of Black Hills stream in South Dakota. Sampling stations were established above and below a development site. Only stations below the sampling site received grazing. Turbidity, temperature, pH, conductivity, hardness, alkalinity, and fecal coliform data were collected at each station. Overall, brook trout were poor indicators of changes in turbidity, temperature, and nutrient loading. However, brook trout densities were responsive to changes in physical stream characteristics.
