Hermit #4, located in Hinsdale, Colorado, is a privately owned earth dam completed in 1947 for recreational purposes such as fish and wildlife pond and recreation. The dam has a height of 10 feet and a hydraulic height of 12 feet, with a length of 290 feet and a storage capacity of 356 acre-feet. It is situated on the South Clear Creek, within the Sacramento District.

Despite its low hazard potential and satisfactory condition assessment, Hermit #4 poses a high risk due to its proximity to residential and recreational areas. The dam has not been modified in recent years and lacks spillway infrastructure. With a drainage area of 4 square miles and a maximum discharge capacity of 2420 cubic feet per second, any potential failure could have significant downstream impacts. Regular inspections are conducted, with the last assessment reported in July 2020.

Water resource and climate enthusiasts interested in the intersection of dam safety, recreational activities, and environmental conservation should keep an eye on Hermit #4. As a privately owned structure regulated by the Colorado Department of Water Resources, its condition and risk management measures are crucial for ensuring public safety and safeguarding the surrounding ecosystem. With the potential for high-risk scenarios, ongoing monitoring and maintenance of this dam are essential to prevent any adverse consequences for the community and environment.
