This map shows a summary of the presence/absence of coho salmon young-of-the-year in streams in the Estuary sub-basin for the
years 2000-2002, displayed with KRIS sub-basins and 1:100,000 scale streams. 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.
