organized by Affected Environment, Environmental Effects, Management Strategy, and References. The Affected Environment provides information on beneficial uses, Stream Condition Inventory (SCI) (Frazer et al. 2005), aquatic management indicator species (MIS) site condition (Hawkins et al. 2000; EPA 2006; Rehn 2009), descriptions of riparian ecotypes (Kaplan-Henry 2000), and past and present effects. The Affected Environment is organized in hierarchal manner using fourth- field watersheds as the largest unit. Fifth,
