Description

Abstract: HabRate represents a simple spreadsheet model that rates the potential quality of stream habitat for the early life stage of salmon and steelhead based on common survey data. The model was developed for a specific application to the middle Deschutes River basin in Oregon, but was intended for general application to the Pacific Northwest Basins. We summarized available literature on salmonid habitat requirements. Habitat requirements for discrete early life history stages (i.e. spawning, egg survival, emergence, summer rearing, and winter rearing) were summarized and used to rate the quality of reaches as poor, fair, or good, based on attributes relating to stream substrate, habitat unit type, cover, gradient, temperature, and flow. Reach level summaries of stream habitat were entered into a computer spreadsheet, and interpreted by logical statements to provide a crude limiting factor assessment of potential egg-to-fry and fry-to-parr survival for each reach. The model is a decision making tool that is intended only to provide a qualitative assessment of the habitat potential of stream reaches within a basin context. Design criteria for the model was simplicity and flexibility. While HabRate was based on our interpretations of the published literature, specific criteria for habitat quality were structure to be easily adjusted where interpretations differ from ours. Information not common to standard stream survey designs, such as seasonal flow or temperature extremes are included as input from professional judgment. A graphic summary of the rating results was present as an example of the potential interpretation.
