Caption:  The Chart Table road_construct_period_lrgsubs.dbf was derived from Matthews and Associates (2001) Table 27. The SUB_BASIN is the CalWater sub-basin naming convention, and the years (i.e. Y1936) are the year of the aerial photos used to estimate miles of road construction. Each period of analysis spans back to the previous aerial photo year. See Info Links for more information.

 50 rows of a possible 125 have been displayed.
