Aquatic Habitat Indicators - Application to the Clean Water Act

Project Parameters

salmonid habitat characteristics

water quality objectives

Pocket Water Inc. served as subcontractor to the Idaho Water Resources Research Institute in evaluating the application of aquatic habitat indicators to the Clean Water Act. The report addresses freshwater, lotic aquatic habitats in the Pacific Northwest and Alaska with an emphasis on salmonid habitat.

Habitat variables were placed into one of the following categories - flow regime, habitat space, channel structure, substrate quality, streambank condition, riparian condition, temperature regime, and habitat access. Candidate habitat variables were evaluated for their relevance to the biotic community, responsiveness to human impacts, applicability to target landscapes, and measurement reliability.
