Site Name: Tributary to Bull Creek
Site Location: Woody County, OH
Receiving Waterbody: Bull Creek→Portage River→Lake Erie
Year Constructed: 2001
Project History and Purpose:
The Tributary to Bull Creek was the first site to implement the two-stage channel design procedure. The project was undertaken primarily to enhance the conveyance capacity of the drainage channel to reduce flooding in the adjacent fields and farmstead. Even small rainfall events would overtop the channel banks and flood near the landowners home and barns. The Tributary to Bull Creek drains a watershed of row crops and agriculture (97%), forest (2%), and residential areas (2%). Watershed soils are Hydrologic Soil Group C and much of the farmland has improved subsurface drainage installed. The project was a collaborative effort between the landowner, Wood County Engineer’s Office, Ohio Department of Natural Resources, and The Ohio State University. Since construction the landowner has noted significant improvements in drainage capacity and in nearly a decade since construction the channel has not flooded out. Furthermore, research ha shown that the Tributary to Bull Creek provides additional water quality benefits by reducing nitrate losses downstream.
