    | 
   Caption:  This chart displays gravel permeability from Middle Navarro River reach WM5 in 1999.  Mean gravel permeability is shown for sampled tailouts (pool-riffle transitions) with whiskers representing standard error. Permeabilities were medium to high for the segmented stream.  Salmonid egg survival index is plotted on the right y-axis and is based on data from Tagart (1976) and McCuddin (1977) indicating high survival (>50%) at two of four locations.  Data provided by Mendocino Redwood Company. See Info Links for more information.
