Irvin, also known as the Doris Irvin Dam, is a private-owned structure located in Durhamville, Tennessee, along the Hatchie River. Built in 1943 by the USDA NRCS, this Earth-type dam serves multiple purposes including fire protection, stock, small fish pond, and fish and wildlife preservation. With a hydraulic height of 11.1 feet and a structural height of 15.3 feet, Irvin has a storage capacity of 50 acre-feet and covers a surface area of 6.1 acres, making it an essential asset for the local ecosystem.

Despite its low hazard potential, Irvin presents a moderate risk level (3) due to its outdated inspection frequency of 5 years. The dam has not undergone a recent condition assessment and lacks an Emergency Action Plan (EAP) meeting current guidelines. While the dam's design and construction are sound, there are concerns about its long-term maintenance and ability to handle potential emergencies. With no outlet gates and an uncontrolled spillway, Irvin's risk management measures need to be updated to ensure its continued safety and functionality for the surrounding community.

In the hands of private owners, Irvin stands as a crucial infrastructure for the conservation of fish and wildlife in the area. However, with its historical significance and current risk assessment, there is a pressing need for updated inspections, maintenance, and emergency preparedness to safeguard this dam and the ecosystem it supports along the Hatchie River in Tennessee.
