E Hamer Smith Dam, located in Marlboro, South Carolina, is a privately owned earth dam with a primary purpose of recreation. Built in 1967 by the USDA NRCS, this dam stands at a height of 17 feet and has a length of 565 feet, providing a maximum storage capacity of 81 acre-feet. The dam overlooks the TR-Hagins Prong river and is regulated by the South Carolina Department of Health and Environmental Control.

Despite its low hazard potential, the dam's condition assessment is rated as poor and it is classified as a very high risk structure. The last inspection in 2017 revealed the need for improvements. While the dam currently has uncontrolled outlet gates, it is equipped with a controlled spillway to manage water discharge. With its picturesque surroundings and recreational offerings, E Hamer Smith Dam serves as both a vital water resource and a potential area for climate enthusiasts to monitor and advocate for necessary maintenance and upgrades to ensure safety and functionality for the future.
