Allen is a federal water resource located in South Dakota, managed by the Bureau of Indian Affairs with a primary purpose of recreation. The earth dam was completed in 1961 and stands at a structural height of 26 feet, with a length of 370 feet, providing a storage capacity of 140 acre-feet. It is situated on No Flesh Creek -TR within the St. Paul District, and is regulated by the Bureau of Indian Affairs.

The dam at Allen has a high hazard potential and a very high risk assessment rating, making it a crucial site for monitoring and management. Despite its high risk, the condition assessment is listed as not available, highlighting the need for further evaluation and potential updates to emergency action plans. With the last inspection date in 2012 and a scheduled inspection frequency of 5 years, ensuring the safety and effectiveness of the dam remains a priority for the Bureau of Indian Affairs.

For water resource and climate enthusiasts, Allen presents an intriguing case study in dam management and risk assessment. With its unique location and purpose, as well as the challenges posed by its high hazard potential, Allen serves as a reminder of the importance of proactive monitoring and maintenance in safeguarding our water resources and infrastructure against potential risks and disasters.
