CALL FOR ARTISTS: Mural Project on Olentangy Trail, Columbus, Ohio

FLOW is seeking Central Ohio artists to turn this Olentangy Trail water pump station into public art!

The Department of Public Utilities (DPU) and Friends of the Lower Olentangy Watershed (FLOW) are working together to use educational public art to promote DPU’s mission, beautify a pump station, and reduce graffiti. This public artwork will be installed to educate the community about the importance of water, rivers, and watersheds in our daily lives and will specifically address the One Water concept. DPU will install accompanying educational signage to explain the mural and how it advances DPU’s mission.

The mural will be installed on a pump station situated the Olentangy Trail between SR 315 N and Goodale Avenue. Pump stations are used to move water against gravity from one location to another. The pump station identified for this art project conveys wastewater to DPU’s water reclamation facility.

Nov. 6 webinar – How does road salt impact the river?

FLOW is participating in SALT WATCH – learn what it is and why it’s important


Road salt is everywhere during winter months. It keeps us safe on roads and sidewalks, but it can also pose a threat to fish and wildlife as well as human health.

Fish and bugs that live in freshwater streams can’t survive in extra salty water. And many of us (more than 118 million Americans) depend on local streams for drinking water. Water treatment plants are not equipped to filter out the extra salt, so it can end up in your tap water and even corrode your pipes.

Abby Hileman of the Izaak Walton League of America will discuss how they are studying the effects of road salt on our waterways. The webinar will cover the following topics:

  • How Salt Watch began
  • Goals of the program
  • What is road/winter salt
  • Salt impacts on wildlife, drinking water, and infrastructure
  • How to participate in Salt Watch
  • When to monitor
  • What to do next (advocacy actions)
  • Regional or national results

FLOW began monitoring in 2022 and plans to continue this year. We welcome more volunteers so we can obtain a clearer picture of how road salt is impacting our watershed.
