At work

Since the beginning of the Chippewa Flood Control System, and during the past twenty-five years, much of the needed maintenance could not be completed as planned due to lack of funding. This caused many of the channel banks to become overgrown with woody vegetation, which made it near to impossible to maintain the banks or the culverts installed for the purpose of draining the floodwaters. In addition, as trees grew, many would lose branches or fall into the channel causing log jams, bank erosion, and more localized areas of flooding due to the inability of the stream flow to get through the blockage.

Maintaining the 33 miles of channel helps to ensure that flood waters will recede from the land, quickly and efficiently.

An effort by the Chippewa Subdistrict has been made to provide funding through an assessment permitted by the Conservancy District Laws of Ohio.

These assessment dollars, which can only be spent on maintenance of the Chippewa Flood Control Project, have been utilized on several projects designed to return the Project to its original design objectives.

Maintenance Activities must be done consistently to keep the Flood Control System working properly. Dams and channels must be mowed annually to manage woody growth, and provide access to allow for equipment and inspections. Visit our Chippewa Creek 05 project to see a recent example of maintenance.

When the Chippewa channel was constructed, nearly 500 pipe structures were installed. These structures used corrugated metal pipes (CMP), which vary in diameter and length, and are an integral part of the System as they move runoff water safely into the channel. The CMP pipes have exceeded their lifespan and are being systematically replaced with superior quality pipe, such as high density polypropylene (HDPP) or high density polyethylene (HDPE). These new pipes are intended to last for many decades.

Special Projects
vary each year and involve items of work that are outside the usual scope of maintenance. They are necessary to keep pace with new standards and regulations, as well as changes in the Watershed.

An example of a special project was the Fencing for Dam VIII-C. All flood control dams are fenced to limit access by livestock and off-road vehicles to prevent damage to the structures. Due to the poor condition of the entry and surrounding fencing, it was removed and replaced.
