Duck is a private fish and wildlife pond located in Henderson, Tennessee, completed in 1999 with a primary purpose of providing habitats for fish and wildlife. The dam, standing at a structural height of 21 feet and a length of 400 feet, has a storage capacity of 65 acre-feet and serves various purposes including fire protection, stock, and recreation. Despite being a low hazard potential structure with a moderate risk assessment, Duck has not been rated for its condition and lacks an emergency action plan.

Managed by the Tennessee state agency, Duck does not fall under federal regulation and has not been inspected since July 2016, with an inspection frequency of 5 years. The dam features an uncontrolled spillway type and covers a surface area of 6 acres with a drainage area of 0.2 square miles. Although the risk management measures and inundation maps are unspecified, Duck serves as an important resource for the local ecosystem and recreational activities, highlighting the importance of maintaining and monitoring water structures for the preservation of water resources and climate sustainability.
