"Are maintenance or flowage easements are on my property?" is a frequently asked question. To help you see where the easements are situated, we have developed the Chippewa Subdistrict Dynamic Map.

With 33 miles of stream channel under maintenance, we deal with many trees each year. As trees age, and fall victim to disease and windstorms, they inevitably come down. A major objective of the Chippewa Project is to maintain the flow capacity of our channels so that large storm events can be managed. In 2020, we saw several wind storms that led to many trees being blown down across the maintenance berms and into the channels. The trees were removed from these areas to prevent logjams and to allow access needed to do channel inspections and channel mowing. This past year, we also continued our maintenance program on the 8 flood control dams.
See Channel Maintenance.

The dams were mowed at least 3 times with some requiring a 4th mowing. The toe drain outlets were repaired on seven of the dams. When the dams were built, the toe drains were installed with corrugated metal pipe and over the years the metal pipe deteriorated and needed replaced. The drains were replaced with PVC materials to ensure that they will function for many more years. To meet a requirement of ODNR Dam Safety, the subdistrict installed a tile drain system at dam 8-C to help drain away excess water on the downstream side of the dam. With the installation of this system, all our dams meet all the current ODNR Dam Safety requirements. Going into 2021, we will continue our focus on the maintenance and inspections of the channels and dams.
See Dam Maintenance.

The eight Chippewa Dams range in age from 40 – 50 years old. We work to keep them in excellent condition, which requires regular inspection and monitoring. How do you safely inspect concrete spillway pipes and that are buried deep, and hundreds of feet long?

Channel Maintenance
Vegetation management is key to preserving channel capacity for flow, and for providing access for maintenance activities along the 33 miles of channel that we are responsible for.

Hubbard Valley Dam Laser Scanning Project
We initiated our first laser scan and 3D basemap of a Principal Spillway structure in 2019 and have continued to leverage that data. At Hubbard Valley Dam, (Dam 3-A), the spillway consists of a 25 foot tall concrete riser, 42-inch diameter by 236 foot long outlet pipe and impact basin. GPD Group – Akron was the contractor. The initial report and drawings provided a very detailed basemap of the spillway. Comparisons of the initial basemap and subsequent scans, will indicate any possible compromises of the structure or the pipe. This level of detail will supplement more basic visual inspections.

StormLink® Instrumentation at Dam 5-D
We installed our third Automated Rainfall and Stage Level Monitoring System with a StormLink® Satellite Monitoring Station in 2019 and utilized that data in 2020. The StormLink® is installed on Dam 5-D, off Steiner Road near Creston, Muskingum Watershed Conservancy District (MWCD) staff installed conduit, concrete supports, and the solar-powered station. We are continuing to monitor the site remotely for rainfall and flood pool stage, which is especially important during large storm events.
