         Sediment: Willow Creek (SW1) - Gravel Permeability, MRC 2000 | 
     
 
 
    | 
   Caption:  This chart shows mean gravel permeabilities (cm/hr) and mean salmonid egg survival index for pool-tails in Willow Creek during 2000.  Whiskers show one standard deviation from the mean permeability.  Salmonid egg survival estimates are based on a relationship originally developed by Tagart (1976) and McCuddin (1977).  Permeabilities range from low to medium.  Salmonid egg survival estimates do not exceed 55 percent in any pool-tail.  Sampling was located in Mendocino Redwood Company's (MRC) long-term monitoring segment SW1 and performed by MRC.  See InfoLinks for more information.
