Walhalla Creek originates just West of Indianola Avenue
The stream flows along Walhalla Road. Once at High Street, the creek continues underground until it joins the Olentangy River.
This stream flows in close proximity to the street, and can be accessed at multiple points throughout the ravine portion of Walhalla Rd.
Clintonville was developed into a neighborhood in the early 1900s. Most homes in the Walhalla area were built between 1920 and 1950. The older infrastructure around the creek makes it susceptible to human impacts such as sanitary sewer overflow during heavy rain events.
In 2012, the Ohio EPA and the Franklin County Environmental Crimes Task Force found two men guilty of illegally dumping wasted (paint) into Walhalla Creek. The dump sites have since been cleaned up, and a neighborhood group now keeps an eye out for similar illegal activity.
