| The data available are
from surveys conducted from 1990-2002. The distribution of a fish species is defined by the presence or absence of a species at a series of sites throughout a stream, watershed, or basin. A survey may be designed to assess
(1) the distribution of a species in a stream or watershed, (2) the upstream limits of fish distribution, (3) the distribution of an assemblage or group of fish in a stream or watershed, (4) the presence
of a rare species, or (5) the distribution of a particular life history stage of a species. The objectives of each survey may differ, but each is designed to establish the presence or absence of fish at some spatial and temporal scale.
All surveys were conducted by Oregon Department of Fish and Wildlife Aquatic Inventories Project located in Corvallis, Oregon. The basins were designated by the State of Oregon Water Resources Department.
