Topic	Sediment: Matthews Road Densities All Big River Sub-basins 2000

 

Caption:  The chart above shows road densities in miles per square mile for all Big River sub-basins as estimated by Matthews (2001) with the overall road density for the entire watershed calculated at 6.86 miles/square mile. Road densities exceed properly functioning condition according to the National Marine Fisheries Service (1996), which, is less than 3 miles per square mile, a value shown for reference above. The lowest road densities are found in the Upper South Fork basin (4.12 mi/sq mi) and the highest are in the Middle Big (8.85 mi/sq mi). Data provided by Matthews and Associates (2001).
