Red lines on the map depict the boundaries of 8-digit hydrologic units (one convenient definition of a watershed) as shown on this 1974 United States Geological Survey Map.

Johnson County drains into two different 8-digit hydrologic units, each represented on the image above by an area between red lines and within the county boundary, designated by a letter. Clicking on a watershed name below will take you to separate page with more information on that watershed.
