Summary of maintenance and special projects completed in 2017.
Vegetation management is key to preserving channel capacity for flow, and providing access for maintenance activities along the 33 miles of channel that we are responsible for.
Eight Chippewa Dams are mowed at least 3 times annually. Debris must be removed from trash racks. Brush control is needed periodically.
Seven Pipe Structures were replaced, and two improved, between Coal Bank and Porr Rds.
All Chippewa flood control dams are regulated by the State of Ohio – ODNR – Dam Safety. Structure II-A required raising the top of Dam about 1 foot, to ensure the Dam will safely pass the required storm events.
We addressed a wet area at the outside toe of the dam. 1670 feet of 6-inch drain tile was installed. 760 feet of old fencing was removed and replaced with maintenance-friendly high-tensile fence.
We installed a StormLink Satellite Monitoring Station which provides the ability to monitor the site remotely, for rainfall and flood pool stage, which is especially important during large storm events.
All Chippewa flood control dams are regulated by the State of Ohio – ODNR – Dam Safety. Each of the eight Dams were designed by the USDA – Soil Conservation Service, to the standards in place at the time of construction in the 1970s. As standards improve, each dam is evaluated and modified as needed to meet the stricter standards in place today. Structure II-A required raising the top of Dam about 1 foot, to ensure the Dam will safely pass the required storm event.
