When planning river restoration projects, proper consideration must be given to the target resources of concern. This should include provisions to meet the physical, hydraulic, and biological requirements of the fish species. Special care is warranted if the restoration efforts are focused on systems that historically contained species of special concern or those listed as Threatened or Endangered (T&E). This paper discusses some of the more important biological considerations that should be addressed as part of river restoration efforts, and by example, illustrates several issues specific to the reintroduction of T&E species (Snake River chinook salmon) into a restored river system in the northwest.
