         Sediment: Annual Mass Wasting Sediment Delivery Rates 1952-1997 | 
     
 
 
    | 
   Caption:  The chart displays estimated annual sediment delivery rates for Garcia River Calwater Planning Watersheds over the period of 1957-1997 (from PWA, 1997).  The reference line shows the estimated natural mass wasting background rate of 162 tons per square mile per year from the EPA Garcia River TMDL (1998).  Sediment yields above the background rate are associated with land use activities and are assumed to be "controllable" by the EPA TMDL (1998).  Click on InfoLinks for more background information.
