This final report discusses the development of a database of freshwater biological traits. The database combines several existing traits databases into an online format. The database is also augmented with additional traits that are relevant to detecting climate change-related effects, especially traits related to temperature tolerances and flow.

This final report uses biological data collected in wadeable rivers and streams, by four states, to examine the components of state and tribal bioassessment and biomonitoring programs that may be vulnerable to climate change. The study investigates the potential to identify biological response signals to climate change within existing bioassessment data sets; analyzes how biological responses can be categorized and interpreted; and assesses how they may influence decision-making processes. The analyses suggest that several biological indicators may be used to detect climate change effects and such indicators can be used by state bioassessment programs to document changes at high-quality reference sites.

EPA is making the link between water quality and quantity and how hydrologic alteration (dams, diversions, interbasin transfers, stormwater, etc) may impair designated/existing Aquatic Life Uses, ways to monitor for it, and ways to implement in State's Water Quality Standards, TMDLs, and NPDES and 404/401 permitting.
