Ten Bensel Dam 3484, located in Holbrook, Nebraska, is a privately owned earth dam primarily designed for flood risk reduction along the TR-Republican River. Completed in 1980, this dam stands at a height of 18.3 meters and has a storage capacity of 104.7 acre-feet, with a normal storage level of 65.5 acre-feet. Despite its low hazard potential, the dam's condition assessment is poor, highlighting the need for maintenance and potential upgrades to ensure its continued effectiveness in protecting the surrounding area from flooding.

Managed by the Nebraska Department of Natural Resources, Ten Bensel Dam 3484 is subject to state regulation, permitting, inspection, and enforcement to maintain its operational safety and integrity. The dam, constructed using stone core and soil foundation, spans 235 meters in length and covers a surface area of 11.5 acres within Furnas County, Nebraska. While the dam has not undergone significant modifications in recent years, its last inspection in October 2018 identified areas of concern, prompting further evaluation and potential action to address its structural deficiencies.

With its proximity to the Republican River and its vital role in flood risk reduction, Ten Bensel Dam 3484 serves as a key infrastructure for water resource management in the region. As climate change continues to impact weather patterns and increase the frequency and intensity of extreme weather events, the maintenance and upkeep of dams like Ten Bensel Dam are crucial in mitigating potential flood risks and protecting communities downstream. Efforts to improve the condition assessment and implement risk management measures will be essential in ensuring the long-term resilience and effectiveness of this critical water resource infrastructure.
