Areharts Pond Dam, also known as Watson Pond Dam, is a private earth dam located in Lexington, South Carolina. Completed in 1955, this dam serves primarily for recreational purposes, with a height of 7 feet and a length of 300 feet. The dam's reservoir has a storage capacity of 57 acre-feet, with a normal storage level of 42 acre-feet and a surface area of 6 acres. The dam is situated along the Hood Branch river or stream, within the Savannah District of the US Army Corps of Engineers.

Despite its low hazard potential, Areharts Pond Dam is in poor condition as of the last assessment in 2017. The dam is regulated, permitted, inspected, and enforced by the South Carolina Department of Health and Environmental Control (DHEC). The inspection frequency is every 5 years, with the last inspection conducted in April 2017. While the dam does not have any associated structures or emergency action plan prepared, it is essential for water resource and climate enthusiasts to monitor its condition and maintenance to ensure the safety and integrity of the surrounding area and ecosystem.
