Situated on TR-Squaw Creek, the earth dam stands at 29 feet high and spans 420 feet in length, with a storage capacity of 44 acre-feet and a surface area of 10.1 acres.
The dam, constructed with a soil foundation, features an uncontrolled spillway and does not have any outlet gates or associated structures. It is designed for the protection of local resources and wildlife, with a focus on maintaining a sustainable water supply and ecosystem balance. Despite not having a current condition assessment rating, the dam is regularly inspected and meets state regulatory standards for operation and maintenance.
Water resource and climate enthusiasts can appreciate Hartman Dam for its role in managing water resources and supporting local biodiversity. The dam's presence along TR-Squaw Creek helps to regulate water flow and provides a habitat for fish and wildlife. As a privately owned structure with state oversight, Hartman Dam exemplifies the importance of responsible water management practices in the face of changing climate conditions.
