Kirby Dam, also known as Wallace Dam, is a concrete structure located in Frierson, Louisiana, along Gandy Bayou. Completed in 1946, this dam serves primarily for recreational purposes, offering a surface area of 18.2 acres and a maximum storage capacity of 400.2 acre-feet. With a height of 48 feet and a length of 4930 feet, Kirby Dam is regulated by the Louisiana Department of Transportation and Development, ensuring state permitting, inspection, and enforcement are in place.

Despite its low hazard potential, Kirby Dam has a moderate risk assessment rating of 3 due to its age and condition assessment not being rated. The dam features an uncontrolled spillway and slide gates for outlet control. While the last inspection was conducted in 2005 with an inspection frequency of every 5 years, the emergency action plan (EAP) status and risk management measures for the dam are currently unknown. Located in Caddo County, Louisiana, Kirby Dam offers a picturesque recreational spot for water resource and climate enthusiasts to enjoy in the region.
