Borehole on section with name—Gray circle and bold name identify borehole on section only

Borehole nameJ-12 WW

Hydraulic head measurement location—Shows name of borehole used to develop potentiometric contours in the regional alluvial-volcanic aquifer

Local groundwater system—Defined by permeable alluvial and volcanic rock of limited extent. Downward leakage is source of localized or diffuse flow to underlying flow system

Regional groundwater flow—Arrow indicates regional flow direction. Arrow width indicates relative flow volume. Arrow and flow-system outline color identifies downgradient flow system. Shading color delineates tributary flow system or flow system labeled on map. The mapped locations of the boundaries of the tributary flow systems and flow systems could be in error by several miles
