Methods to evaluate impacts on fishery resources due to man-induced projects are often time consuming and prohibitively expensive to perform. Resource managers are confronted with numerous projects, low budgets, and few personnel to perform the required evaluations. By limiting the impact evaluation to those variables that are known to be affected by a project, the evaluator can more easily make sound predictions. This paper outlines a method of impact evaluation applied to a hydropower development utilizing a single habitat suitability index curve for each of two fish species to predict the direction of change in representative fish populations inhabiting specific habitat types.
