About Carter Lake Dam
The primary purpose of Carter Lake 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 David Agers (private). It impounds the Tr-maddin Creek near Morse Mill.
The dam stands 62 feet tall and stretches 600 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 80 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1957, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 07/10/2018.
