Most permanent bodies of water in the Southwest have one or more species of fish as inhabitants, and ephemeral streams may temporarily support fish. Thus, presence of "fish," without further identification, is relatively uninformative. Fish do, of course, imply presence of water within some distance of a site, but that distance may be highly variable. Various species of birds may capture or scavenge fish and later deposit the fish remains at a distant site. Harris (1977) suggested that most carry-in elements likely originate from less than 6 miles away, and that there is a practical limit of about 15-20 miles. Thus in areas currently extremely arid, some useful information on the presence of permanent water may be obtained.
