Monke Dam, located in Hettinger, North Dakota, is a privately owned earth dam that was completed in 1934 by the Civilian Conservation Corps (CCC). With a height of 13 feet and a length of 325 feet, this dam serves primarily for recreational purposes, offering a serene setting for outdoor activities. The dam is situated on the THIRTYMILE CREEK-TR river, within the jurisdiction of the North Dakota State Water Commission (NDSWC) and is regulated, permitted, inspected, and enforced by the state agencies.

Despite its low hazard potential and moderate risk assessment, Monke Dam has not been rated in terms of its condition assessment. The dam has a storage capacity of 64 acre-feet and is equipped with an uncontrolled spillway. It does not have any outlet gates or associated structures, and its risk management measures are currently unspecified. The dam has not been modified in recent years and has not had an emergency action plan prepared or updated.

Monke Dam, under the oversight of the North Dakota state authorities, stands as a testament to the early 20th-century engineering efforts in providing recreational amenities and water resource management. Its historical significance and modest risk make it a noteworthy site for water resource and climate enthusiasts seeking to explore the intersection of infrastructure development and environmental conservation.
