Abstract
We assessed the precision of the habitat quality index (HQI) model II, a model for rating habitat quality in trout streams and predicting fish standing stocks. This is a deterministic model, and its precision depends on the ability of observers to generate similar input values. Three 50-m stream reaches were evaluated by three teams per reach. Among individual attributes, measurements of cover and eroding bank had the greatest variability. Our results demonstrate the need for more thorough definition of these attributes to reduce subjectivity and associated measurement variability.Keywords
