Topic	Sediment: Road Densities in PALCO Watersheds

Caption:  The Chart Table sedsum_PL summarizes, for Mattole and Bear River sites, sediment and road density data where each were reported in the PALCO HCP. RDMI/SQMI is the road density in the watershed above each station in miles per square mile. COBBD84 and COBBD50 are particle diameter representing the 84th and 50th percentile in particle size frequency distribution ( by Wollman pebble count). SEDLT_85 and SEDLT_470 are proportion of gravel samples, by weight, less than 0.85 and 4.7mm., respectively. Values for streambed conditions are averages of the two years sampled for each station. Actual years varied among sites, but all occurred in the period 1991-1996. See Source Table for more details.

 50 rows of a possible 222 have been displayed.
