Spy Run Creek is a tributary of the St. Marys River that runs from northwest Allen County to Lawton Park in Fort Wayne. It is in Lawton Park that the creek empties into the St. Marys River.
In addition to Lawton Park, Spy Run Creek also flows through Franke Park. The creek is subject to flooding, as a result, homes on Eastbrook and Westbrook streets, north of State Boulevard, were removed. In addition the bridge on State was rebuilt to mitigate flooding on State.
The Pufferbelly Trail crosses Spy Run Creek here.
