         Sediment: Fines <5.6mm from SF Big River 2000 |

   Caption:  The chart above shows percent fine sediment levels <5.6mm from dry-sieved McNeil samples in South Fork Big River, 2000.  Fine sediment was above the adjusted dry-sieve target of 26% in all tailouts, excluding #4. The reference value of 26% represents a reference for dry-sieved samples based on the Big River TMDL and Sharazi and Seim (1979). This conversion is not necessarily endorsed by the EPA.  The 6.4mm class size was not reported by MRC.  The charted < 5.6mm values are conservative in comparison to the target because they do not include fines between 5.6 and 6.4mm.  Data provided by the Mendocino Redwood Company.  See Info Links for more information.  Click on Picture to see a map of MRC Big River monitoring locations.
