About Texas Gulf Reservoir Dam
The primary purpose of Texas Gulf Reservoir 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 Pcs Phosphate Company Inc (private). It impounds the Off Ch-san Bernard River.
The dam stands 10 feet tall and stretches 13,300 feet across, and has a maximum storage capacity of 2,875 acre-feet. Completed in 1929, the structure is well-established, with more than 75 years of service.
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. The most recent inspection on record was 03/25/1976. That was over 50 years ago.
