Habitat Suitability Index Models: A Low Effort System for Planned Coolwater and Coldwater Reservoirs (Revised)

摘要

A technique is described for measuring reservoir habitat suitability based on a composite score for five primary reservoir attributes (temperature, turbidity, nonliving cover, drawdown, and shallow cove frequency). The value of each primary attribute is determined from secondary attributes, which are easily obtained from published data and on-site inspection of the proposed reservoir basin. Subsequently, the use of primary attribute scores to determine reservoir habitat suitability for five selected fish species is described. This approach has the advantages of procedural simplicity and ready availability of input data. The intended use is during the early planning stages of reservoir construction projects, when the outcomes of alternative plans are being evaluated.
