Summary of maintenance and special projects completed in 2019.
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.
With this year’s extra rainfall, we’ve increased mowings up to four per year for most dams and removing debris removal from trash racks.
Four Pipe Structures were replaced on Channel Reaches LC02, CC05, and CC11. Access was improved at Dam 7-C and Coal Bank Road gates.
In 2019, we used our first laser scan and 3D Basemap to indicate any possible compromises of a Principal Spillway structure.
Installation of the StormLink® Satellite Monitoring Station allows remote monitoring during heavy rainfall and storm events.
For many years, it has been sufficient for the eight Chippewa Dams to be mowed at least three times annually. Again for 2019, for this year’s growing season and extra rainfall, we’ve adjusted to four mowings per year for most dams. Debris removal from trash racks occurs as needed.
