Get started by selecting one of the "Zoom to" drop-down menus above the map or a tear-drop icon on the map. Clicking on a tear-drop will open a window with features and links to more information for that water trail.
Gauges and access points will only display after using the drop-down or tear-drop window zoom options.
If the blue highlighting for a water trail obscures your view it can be turned off by un-checking the "Water Trail" check-box above the map.
Additional trail information is listed by river basin below the map.
