From Unnamed Tributary To Coyote Run: Southern Clark County Stream Is Officially Named

WYSO | By Chris Welter Published August 31, 2020 at 2:48 PM EDT

A small waterway in southern Clark County is now officially named Coyote Run.

In 2017, Enon Sand and Gravel, a subsidiary of Jurgensen companies, went to the Ohio Environmental Protection Agency to ask for a National Pollutant Discharge Elimination System (NPDES) permit to discharge water from their proposed mining operation into a small local waterway that runs through private farmland. The company and the state called the waterway an “unnamed tributary.” Kathleen Mathews, who’s on the board of the environmental group Mud Run Conservancy, says that gave her an idea.

“It was so small and so insignificant it didn’t have a name. It just really annoyed me.” She says “that was part of the reason nobody was upset and so I just decided that I was going to try to figure out how you get things named.”

In July, the Mud Run Conservancy’s application to name the tributary was approved by the United States Board of Geographic Names. Now, the tributary is officially known as Coyote Run.

Do you know how long it takes to OFFICIALLY name an unnamed waterway? For us it took just a smidge more than a year! The “Name that Creek” contest was launched at the Enon Parade on July 4, 2019.

Do you know about the redside dace? This fish is a cold-water indicator s.pecies found in an unnamed tributary of the Mud Run. A robust and sustainable population was observed  in the stream on June 8 of 2018!
Help improve the waters in the Mad River Watershed by attending any of the following activities:


  • Write the director of the Ohio Division of Natural Resources, Mary Mertz and request the Mad River receive a scenic river destination due to its unique spring fed waters and its important cold water fisheries.
  • Volunteer with Mud Run Conservancy and educate the citizens about the abundant water resources of our township and the need to protect and preserve them.
  • The Mad Men of Trout Unlimited is an organization whose focus is to study, protect and restore the Mad River. This year’s annual meeting will be held at the Simon Kenton Inn from 7-9:00 pm on March 21, 2020. Get involved with Trout Unlimited and protect The Mad, Ohio’s principal trout stream of Ohio.
