About Clymers Basin Dam
The primary purpose of Clymers Basin Dam is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is owned by Michigan Limestone Operations (private). It impounds the Trib To Lake Huron near None-lake Huron.
The dam stands 65 feet tall and stretches 6,346 feet across, creates a reservoir covering 65 acres, has a maximum storage capacity of 2,275 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1999, the structure is 27 years old.
