Key to Methods - Overall Ratings & Rating Strength
Overall Ratings: These ratings are a combination of the Total Watershed Rating and the Total Biological Rating. All ratings have been standardized to a 0 to 10 range based on the results for all watersheds statewide. Watersheds without survey efforts are unranked.
Rating Strength: Ranking Strength represents an estimate of the level of confidence in the ratings. The ranking strength reflects the number of surveys, the types of surveys, and the distribution of surveys within the stream reaches. It is expected that the number of species observed (a major component of the rank) will increase with increased survey efforts, and the ranking strength gives the reader a way to evaluate the accuracy of the current stream rank. All ratings have been standardized to a 0 to 10 range based on the results for all watersheds statewide. Watersheds without survey efforts are unranked.
