Topic	Sediment: Matthews Road Construction by NF sub-basin 1933-1999

 

Caption:  The chart above shows the miles of road construction by period for each North Fork Ten Mile River sub-basin. Estimates are generated largely from aerial photos and years shown above are the year of the photo used and cover the period back to the previous photo year. 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)."
