         Habitat: Pool Depth by Percent Survey Length for Northern Tribs | 
     
 
 
    | 
   Caption:  The California Department of Fish and Game measures maximum depth for every pool surveyed.  Pools with depths in excess of 3 feet provide higher quality salmonid rearing and holding habitat.  These higher quality pools comprise less than 1% of the survey length in all but the three largest Northern Mattole streams.  Stream order was used to arrange reaches from top (higher order; large) to bottom (lower order; small) because drainage area was not available. See Info Links for more information.
