This is the first approximation of a graphical approach to querying available information by fifth-field HUC
To zoom in or out you can click the "+" and "-" symbols in the upper left of the map panel. Alternatively, you can hold down your "shift key", and use the mouse to outline an area to zoom in on.
Use the up/down or left/right arrows to pan, or hold the left mouse key down and drag the image
Click the "+" sign in the upper right of the map panel to choose different base layers and map overlays
When the fifth-field HUC layer is checked you can left-click on a HUC to access a data query for that fifth-field HUC.
