Topic	Fish: Presence/Absence of Coho in Guerneville Sub-basin 1988-1999

 

Caption:  This chart shows a summary of the presence/absence of coho salmon young-of-the-year in streams in the Guerneville sub-basin based on sampling that took place from 1988-1999. Each stream was only sampled once and coho salmon were found only in Ward Creek. The numbers shown on the chart bars indicate the number of years in which surveys found coho presence (green) or absence (red) for each stream. This chart contains data for all the streams listed as known historically to harbor coho salmon in a draft California Department of Fish and Game 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. See InfoLinks for more information.
