To save any other Midwestern comrades an hour of searching to get any info about it:

• This is in Mill Creek, near Washington, KS.
• It's in the very north of the state, on the Nebraska border, due north of Wichita
• Downstream of this creek, based on GIS water data
  • Little Blue River,
  • Big Blue River
  • Tuttle Creek Lake
  • Kansas River
  • The cities of Manhattan, Wamego, Topeka, Lawrence, through on to Kansas City
  • Missouri River
  • Jefferson City, MO
  • Mississippi River at St. Louis MO
  • The Mississippi all the way on down through Memphis, Little Rock Baton Rouge, NOLA, and out into the Gulf of Mexico

No idea what the practical impacts will be. But it's a river. Shit rolls down hill, shit flows downstream.
