Figure 19. Calculated annual groundwater withdrawals by pumping region for the base-case analysis and analysis of reduced background pumping for (A) annual pumping in the southern Tule Lake region; (B) annual pumping in the northern Tule Lake region; and (C) annual pumping in the Klamath Valley region, upper Klamath Basin, Oregon and California, 1970–2004. Results shown are for the years with unmet groundwater demand in the base-case groundwater-management analysis. Base-case and Remove background pumping are groundwater-management-model formulations defined in table 1.
