         Sediment:  DG to TB - Bed Surface Composition D50 1980-2000 |

   Caption:  This chart shows the median (d50) bed surface particle-size from Wolman pebble counts in Lagunitas Creek riffles at monitoring sites between Devils Gulch and the Tocaloma Bridge. Major decreases in surface d50 in 1997 suggests bedload movement associated with January 1, 1997 peak flows. Data were collected during the summer and fall of years 1980 to 2000 by Balance Hydrologics, Inc. for the Marin Municipal Water District.  See chart table caption for site names. Sites are listed upstream to downstream in the chart legend.  See Map to view sediment sampling locations and Info Links for more information.
