Porter Dam, located in Deshler, Nebraska, is a privately-owned structure designed for flood risk reduction along TR-Spring Creek. Completed in 1980, this earth-type dam stands at a height of 12.5 feet and spans 300 feet in length. With a normal storage capacity of 34.9 acre-feet and a total NID storage of 133.7 acre-feet, Porter Dam serves as a crucial asset in managing water resources in the Nuckolls County area.

Despite its importance, Porter Dam has been assessed as being in poor condition as of April 2017, with a low hazard potential. The dam is under the jurisdiction of the Nebraska Department of Natural Resources and is subject to state regulation, permitting, inspection, and enforcement. While the dam's emergency action plan status and risk assessment measures are not clearly outlined, its operational and safety aspects are monitored with a five-year inspection frequency in place.

As an essential component of the local water infrastructure, Porter Dam plays a vital role in flood control and water resource management in the region. While facing some maintenance challenges, the dam's significance in mitigating flood risk along TR-Spring Creek underscores the importance of ongoing monitoring and maintenance to ensure its continued effectiveness in safeguarding the surrounding communities and ecosystems.
