This map shows a summary of the presence/absence of coho salmon young-of-the-year in streams in the North Fork Navarro
sub-basin for the years 2000-2002, displayed with KRIS sub-basins and 1:100,000 scale streams. Coho salmon have been
extirpated from the northern portion of the project area, but persist in the southern portion. This map contains data for all the
streams listed as known historically to harbor coho salmon in a draft California Department of Fish and Game database, but there
are likely other historical coho streams that are not included in that database. Absence data are provisional pending more extensive
study, because coho may exist in some streams but only occur in some years or may have resided in other reaches of streams not
surveyed. This map/database groups data at the scale of entire streams, and differences in coho presence/absence between
different reaches in the same stream are not shown.
