Welch Dam, located on the Cannonball River in North Dakota, was completed in 1936 and serves the primary purpose of recreation. This earth dam, with a structural height of 23 feet and a length of 350 feet, provides a storage capacity of 88 acre-feet and covers a surface area of 15.5 acres. The dam is regulated by the North Dakota State Water Commission (NDSWC) and is subject to state permitting, inspection, and enforcement.

Despite being classified as having a low hazard potential, Welch Dam is considered to have a moderate risk level, with a risk assessment rating of 3. The dam has not been rated for its condition, but it meets the state jurisdiction and regulatory requirements. The last inspection of Welch Dam took place in October 2002, and the dam has not undergone any modifications since its completion. Although it does not have a formal Emergency Action Plan (EAP) in place, the dam is equipped with an uncontrolled spillway and is monitored for its risk management measures.

Overall, Welch Dam is a vital structure for both water resource management and recreational activities in the area. Its historical significance as a Works Progress Administration (WPA) project adds to its appeal for water resource and climate enthusiasts who appreciate the engineering feats of the past and the ongoing efforts to ensure the safety and functionality of such infrastructure.
