||Sediment: Matthews Large Basin Areas Road Construction 1921-2000
||Caption: The chart above shows the miles of road constructed by period for KRIS Big River sub-basins. Road construction continues to be active in the Big River watershed. Matthews and Associates (2001) state: "Analysis indicates that sediment production from roads has increased significantly over the study period, tracking cumulative road construction." Road data was derived from aerial photographs and from CDF data for more recent periods. Aerial photograph work focused on main and haul roads.
