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

Caption:  The Chart Table sed_road_mill_mcrcdpwa_98.db shows the number of sites and future sediment yield from six categories of road-related potential erosion sites in Mill Creek, based on data collected during phase 1 (PWA, 1999). Data were provided by the Mendocino County Resource Conservation District and Pacific Watershed Associates (1999). See Info Links for more information. A key to column headings: Problem_Type = categories of problem types, 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_Treat = Amount sediment predicted to be delivered to a stream at sites recommended for treatment (calculated by multiplying total potential erosion by the probability of delivery to a stream) if no work was done, Future_Yield_NoTreat = Amount sediment predicted to be delivered to stream for sites not recommended for treatment.

 50 rows of a possible 167 have been displayed.
