Your Money | What's NEW?

A substantial effort was made in 2018 to ensure that all 8 of the Chippewa Flood Control Dams meet current Ohio Dam Safety requirements. In recent years, the Standards for dams such as ours, have been raised by the Ohio Department of Natural Resources – Dam Safety. Our dams have been analyzed, and must demonstrate that they can safely pass larger storm events, compared to their original design. In the case of Dam 5-D, we were required to raise the top of the dam a relatively small amount, and “armor” the Auxillary Spillway. The dam raising was completed by the MWCD’s own earthmoving crew. The work to install the Turf Reinforcement Matting was contracted for a cost of $79,000.

Maintenance berms alongside nearly the entire 33 miles of Channel provide us the access to perform channel inspections, periodic mowing, and the maintenance/replacement of pipes. Most of our maintenance berms are mowed annually, while others still require attention. In addition, year-round access to our 8 Dams is required for debris cleanup and inspections. In 2018, roughly 3/4 mile of access lanes and maintenance berms were improved.

Chippewa Dam 5-D Spillway Improvement
To protect the integrity of the Auxillary Spillway, approximately 3000 square feet of High Performance Turf Reinforcement Matting has been installed.
