We sketch an iterative assessment process for the effects of climate change on freshwater fisheries that uses water temperature, water quantity, and water quality variables to link the atmosphere to fishery resources. Iterative interaction among atmospheric, ecological, and fisheries scientists clarifies the information needs of each discipline and progressively improves the assessments of effects. The process incorporates information at different scales, i.e., organism/laboratory, species/habitat, and population/ecosystem. We illustrate the operation of the iterative assessment process with recent work done on the water temperature linkage, and sketch some linkages through water quantity and water quality variables. A Wild Salmonid Watch (WSW) could provide a framework for monitoring climate change and its effects on salmonid stocks on a hemispheric scale. We discuss the initial steps required to mobilize a WSW for climate change and its role as climate change develops in the decades ahead.
