Case StudiesFor many years, ecological restoration has been a valuable tool for fisheries biologists and other resource managers. Hundreds of restoration projects have resulted in improved fisheries, reduced flood potential, and increased recreational amenities. Ecological restoration has only recently been considered for use by water quality managers, an d few projects are adequately documented. Although improving water quality is not always the primary objective for stream and river restoration projects described in this chapter, these case studies do demonstrate the effectiveness of using restoration t echniques to achieve water quality goals. Common elements among the case studies that resulted in improvements to stream integrity are the reduction of stressors and the restoration of stream components (e.g., stream channel and riparian corridor). None of the case studies demonstrate a framewor k entirely consistent with recommendations provided in this document; each project does, however, offer unique lessons that may be beneficial in planning future projects. Presentation of case studies is therefore structured in accordance with the framewo rk presented in this document. This consistent format for all case studies provides a common basis for evaluating individual examples and comparing different approaches. The following categories are used to describe the case studies:
Because the range of available information varies with each case study, presentation and content vary somewhat. Table 6-1 summarizes all six case studies included in this chapter.
