Lambert, located in Blount County, Tennessee, is a privately owned earth dam designed by the USDA NRCS for fire protection, stock, and small fish pond purposes. Completed in 1965, this dam on Big Spring Branch has a hydraulic height of 48.4 feet and a structural height of 53.9 feet, with a storage capacity of 454 acre-feet. The dam has a high hazard potential and a moderate risk assessment rating, making it a key structure for water resource and climate management in the area.

Despite its importance, Lambert has not been rated for its condition assessment and lacks emergency action plans and inundation maps. The last inspection in August 2016 highlighted its high hazard potential, prompting a five-year inspection frequency. With no outlet gates and an uncontrolled spillway, the dam poses a significant risk, emphasizing the need for proactive risk management measures to ensure public safety and water resource sustainability in the region.

As a valuable asset for fire protection, stock, and recreation, Lambert serves as a critical infrastructure in the Nashville District of Tennessee. With its location in Sixmile and its key role in managing water resources in the area, Lambert stands as a reminder of the importance of maintaining and monitoring dams for sustainable water management practices and climate resilience in the face of changing environmental conditions.
