Topic	Sediment: Matthews Road Construction by Large Basin Areas 1933-1999

 

Caption:  The chart above shows the miles of road construction by period for large Ten Mile River sub-basins. The period of greatest road construction is 1988 to 1999 in all sub-basins except for the Lower Ten Mile. Estimates are generated largely from aerial photos. Matthews Associates (2000) state: "Prior to 1988, the history was developed primarily from interpretation of aerial photography. From 1988 to present, road and harvest history was obtained from CDF GIS coverages which had been developed by directly inputting information provided as part of submitted Timber Harvest Plans (THPs)."
