Van Gorder Ditch

Site Name: Van Gorder Ditch
Site Location: Steuben County, OH
Receiving Waterbody: Cedar Creek→St. Jospeh River→Maumee River→Lake Erie
Year Constructed: 2008

Project History and Purpose:
The Van Gorder Ditch is in the Little Cedar Creek watershed, an area identified in the Cedar Creek Watershed Plan (2005) as a critical area providing excessive sediment to Cedar Creek. The channel drains a watershed consisting of row crops and pasture (68%), forest (6%), urban and residential areas (22%), and water and wetlands (4%). Soil types in the watershed include Hydrologic Soil Groups A, B, C, and D. Van Gorder Ditch was a trapezoidal shape and required frequent maintenance to reconstruct the original shape. This may be in part due to the development of residential and urban areas upstream. The channel was reconstructed to a two-stage geometry and hydro-seeded to establish vegetation. Before vegetation could fully establish a flood event eroded the benches and cut into bank slopes in several locations. Following the flood event additional erosion control features were constructed to reduce overland flow on the ditch sideslopes which caused some gulley erosion. Additionally the site was reseeded again using the hydro-seeding method.  The project was undertaken by the St. Joseph River Watershed Initiative with funding and in-kind donations from the Indiana Department of Environmental Management, Maumee River Basin Commission, and Noble County Surveyors Office to implement the two-stage channel design.
