Tomahawk Dam, located in Barnes County, North Dakota, is a Federal-owned structure managed by the Fish and Wildlife Service. Built in 1936, this earth dam stands at a height of 11 feet and spans 500 feet in length, creating a fish and wildlife pond for conservation purposes. The dam has a normal storage capacity of 369 acre-feet and a drainage area of 103.5 square miles, providing critical habitat for the local ecosystem.
Over the years, Tomahawk Dam has undergone several modifications to enhance its structural and hydraulic integrity, with the most recent upgrades in 2012. Despite being classified as having a low hazard potential, the dam's condition assessment in 2013 rated it as poor. With a moderate risk level assigned, it is crucial for ongoing risk management measures to be implemented to ensure the safety and longevity of this vital water resource infrastructure.
As enthusiasts of water resources and climate change, understanding the importance of maintaining and evaluating structures like Tomahawk Dam is essential in safeguarding our environment and wildlife habitats. With regular inspections and risk assessments, coupled with proactive management strategies, we can work towards preserving these valuable assets for future generations to come.
