Johnson Co

Johnson County is the fastest growing area in Kansas, and the rapid pace of development has a big impact on the Kansas River. Below is a static map and at the bottom of the page is a Google Earth version that is interactive.

Map Key:
  • Johnson County is highlighted in red
  • The Lower Kansas River Watershed is outlined in white
  • Within the watershed the water that falls on Johnson County drains to the Kansas River, as shown by the yellow arrows
  • The remainder of Johnson County, outside of the Kansas River Watershed, drains to the Missouri River
