||Caption: The chart above shows the miles of road constructed by period for the Lower Big River sub-basins. Road construction activity has recently increased in most of the sub-basins. Middle Big River shows the most recent construction and cumulative miles of road. Road data was derived from the CDF and aerial photographs by Matthews and Associates (2001). Aerial photograph work focused on main and haul roads. See Info Links for more background information and links to references.
