Yourk Dam, also known as Walter J Dam, is a privately owned structure located in North Dakota along Whitetail Creek. Built in 1969 by the USDA NRCS, this earth dam stands at 32 feet tall and stretches 454 feet in length, with a primary purpose of serving as a fire protection, stock, or small fish pond. With a storage capacity of 55 acre-feet and a drainage area of 0.16 square miles, Yourk Dam plays a crucial role in managing water resources in the region.

Despite its low hazard potential, Yourk Dam is regulated by the North Dakota State Water Commission and undergoes regular inspections, with the last one conducted in 1979. The dam features an uncontrolled spillway with a width of 133 feet and poses a moderate risk, as indicated by a risk assessment rating of 3. While its condition is currently not rated, the dam is equipped with emergency action plans to ensure prompt response in case of any unforeseen events. For water resource and climate enthusiasts, Yourk Dam serves as a fascinating example of how private entities contribute to water management and environmental conservation efforts in the region.
