Cass County dam may need upgradedam on a tributary of Swan Creek just north of Absaraka in western Cass County took a pounding from the recent record flooding in the area.
ABSARAKA, N.D. (AP) — A dam on a tributary of Swan Creek just north of Absaraka in western Cass County took a pounding from the recent record flooding in the area.
Erosion on the earthen spillway cut a hole 10 feet deep. It prompted 24-hour monitoring by the National Guard, and required emergency repairs.
Chad Engels, an engineer for the Maple River Water Resource District, said repairs and possibly an upgrade of the dam itself may be in the works. He said repairs to the spillway could cost around $100,000 and upgrades to the dam would cost hundreds of thousands of dollars.
The water resource district is working with the Natural Resources Conservation Service on funding. Such projects normally have a 75-percent federal, 25-percent local cost share.
Officials expect to know more in about a week.
