Puget Sound Characterization: The Water Resource Assessments (Water Flow and Water Quality) (PDF) (74 pp, 6.4MB) The Puget Sound Characterization is a set of water and habitat assessments that compare areas within a watershed for restoration and protection value. It is a coarse-scale decision-support tool that provides information for regional, county and watershed-based planning. The assessments cover water resources (both water flow and water quality) and fish and wildlife habitats (in terrestrial, freshwater and marine nearshore areas) over the entire drainage area of Puget Sound. The assessments provide a watershed-scale perspective on the relative importance of small watersheds for the protection and restoration of water resources and habitats that is not generally provided by other available tools. Final results can also be analyzed to identify the basis for a small watershed’s relative importance, and to guide potential management strategies for that watershed. The information it provides will allow local and regional governments and others to base their decisions regarding land use on a systematic analytic framework that prioritizes specific geographic areas on the landscape as focus areas for protection, restoration and conservation of the region’s natural resources, and that also identifies areas that are likely more suitable for development.

Implementation of Tiered Aquatic Life Uses in Maine As part of its water quality standards, the Maine Department of Environmental Protection analyzed its aquatic biomonitoring data using a probability-based statistical model to assign each of the state’s water bodies to one of three aquatic life use classes. As new biomonitoring data are collected, the state confirms that each water body is attaining its aquatic life use designation and incorporates any water bodies that are not attaining their aquatic life use designations in its 303(d) list of impaired water bodies.

Ohio’s Statewide Biological and Water Quality Monitoring and Assessment To assess the attainment and appropriateness of the water quality designations assigned to its streams and rivers, Ohio EPA monitors water chemistry and fish and macroinvertebrate assemblages in all of its streams and rivers on a rotating basis. In addition to supporting the development of the state’s 303(d) list, these data are used to determine whether or not Ohio’s streams and rivers adequately support aquatic life (including consumable fish), recreational opportunities and drinking water supplies for the state as a whole. Other agencies have also used bioassessment data and biocriteria to assist with management of rare, threatened and endangered species, scenic river designations, environmental impact assessment and fisheries management.

The Importance of Biocriteria in North Carolina's Basinwide Management Strategy The North Carolina Division of Water Quality (DWQ) has been using bioassessment techniques to evaluate water quality for more than 15 years. Biological data are valuable for classifying Outstanding Resource Waters (ORW) and High Quality Waters (HQW). In order to be classified as ORW or HQW, the stream must receive a biological rating of "Excellent." State standards allow waters designated as ORW or HQW to be protected through such means as advanced treatment requirements, restriction of new discharges, land use regulations and storm water controls.
