Area Freshwater Creek-Ryan Slough
Topic Sediment: Fines <0.85 mm at All Freshwater Sampling Sites 1994-1999
Caption:  This chart shows Freshwater Creek basin fine sediment data from PL monitoring sites from 1994-1999 for particles less than 0.85 mm, which can infiltrate into redds and smother salmonid eggs. The reference line of 14% fines (<0.85 mm) is similar to that chosen to represent properly functioning condition for cold water fish by the U.S. EPA (1998) for TMDL compliance. Four sites fell within optimal ranges according to this criterion in some years. See InfoLinks for more information on fine sediment and aquatic health. Data from the PALCO.
