About Silt Pond
The primary purpose of Silt Pond 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 Cemex Construction Materials, Inc. (private).
The dam stands 25 feet tall and stretches 800 feet across, and has a maximum storage capacity of 5 acre-feet.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam.
