Brinkman Dam, located in Tecumseh, Nebraska, on the TR-N FK BIG NEMAHA RIVER, is a privately owned structure that serves multiple purposes, including flood risk reduction. Completed in 2007, this earth dam stands at a height of 24 feet and has a structural height of 29 feet, with a total length of 470 feet. It has a maximum storage capacity of 63 acre-feet and a normal storage level of 14.5 acre-feet, covering a surface area of 3 acres and draining a 0.3 square mile watershed.

Managed by the Nebraska Department of Natural Resources, Brinkman Dam has a low hazard potential and is deemed to be in satisfactory condition as of the last assessment in May 2019. The dam has state jurisdiction and is subject to regular inspections, with a mandated inspection frequency of 5 years. In the event of an emergency, the dam lacks an Emergency Action Plan (EAP) and updated contact information, raising some concerns about the preparedness for potential risks associated with the structure.

Despite its modest size and storage capacity, Brinkman Dam plays a crucial role in mitigating flood risks along the TR-N FK BIG NEMAHA RIVER in Johnson County, Nebraska. Water resource and climate enthusiasts interested in the intersection of infrastructure, water management, and environmental stewardship can appreciate the significance of this privately owned dam in safeguarding the local community and surrounding areas from potential flood events.
