About Guy Branch Holding Pond
The primary purpose of Guy Branch Holding 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 The Mosaic Company (private). It impounds the Thirtymile Creek But Wmd Says Guy Branch near Mulberry But Wmd Says Nichols.
The dam stands 24 feet tall and stretches 1,000 feet across, creates a reservoir covering 80 acres, and has a maximum storage capacity of 1,650 acre-feet. Completed in 1971, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 09/11/2014. That was over 11 years ago.
