Water quality rank 



Water quality scoring relied on three fields, all based on potential of streams (in restored 

 condition) to reduce instream sediment, water temperature and nutrients to downstream waters. 

 Scoring produced four ranked classes (high, moderate, low and none), with 73 of 83 (88%) 

 impaired tributaries as having some (i.e. one of three criteria) water quality improvement 

 potential (Figure 10). Nineteen of 33 (58%) project streams ranked high in water quality 

 potential, compared to 20 of 50 (40%) non-project streams (Figure 1 1 ). Based on scoring criteria, 

 potential to improve water quality through at least one of the three variables occurs in 95% of 

 project and 80% of non-project streams. Ten streams ranked as having no potential for improved 

 water quality (Table 5).
