Topic	Sediment: Road-Related Erosion Sources by Volume in Mill Cr 1998-99

Caption:  The Chart Table sed_road_mill_mcrcdpwa_98_99.db shows the number of sites and future sediment yield from four categories of road-related potential erosion sites in Mill Creek, based on data collected during phase 1 (1998) and phase 2 (1999) road surveys. Data were provided by the Mendocino County Resource Conservation District and Pacific Watershed Associates (1998 and 2002). See Info Links for more information. Column headings begin with a prefix indicating the data type, and end with a suffix indicating the time period in which data were collected. A key to column headings: Problem_Type = categories of problem types, Num_Sites_ = the number of sites in a problem category, Num_Sites_Treat_ = the number of sites in a problem category recommended for treatment, Num_Sites_NoTreat_ = the number of sites in a problem category not recommended for treatment, Future_Yield_ = Amount sediment predicted to be delivered to stream (calculated by multiplying total potential erosion by the probability of delivery to a stream), _Ph1 = Phase 1 surveys (1998), _Ph2 = Phase 2 surveys (1999).

 50 rows of a possible 167 have been displayed.
