    | 
   Caption:  This chart shows the index of salmonid abundance measured by Rob Leidy for Marin County streams sampled sometime in the period 1992-1998.  This index describes the percentage of sample consisting of salmonids (1-3 scale, where 0 = no salmonids, 1 = 1-24 salmonid individuals, 2 = 25-50 salmonids, and 3 = >50 salmonids).  Sample sites were at least 30 meters in length and represented multiple habitat types.  Surveys typically used block nets and electrofishing.  See Info Links for more information.
