Hirsch Dam, located in Dakota County, Nebraska, is a privately owned structure designed by the USDA NRCS for the primary purpose of flood risk reduction. Completed in 1966, this earth dam stands at a height of 30.1 feet and has a length of 533 feet, with a storage capacity of 49.2 acre-feet. Despite its low hazard potential, the dam's condition assessment in 2019 rated it as poor, highlighting the need for maintenance and potential repairs to ensure its continued effectiveness in managing water resources along the TR-PIGEON CREEK DITCH.

Managed by the NE DNR, Hirsch Dam is regulated by the state of Nebraska and undergoes regular inspections to assess its structural integrity and operational efficiency. Its location within a drainage area of 0.75 square miles and its ability to discharge up to 591 cubic feet per second make it a critical component in mitigating flood risks in the region. Despite its current condition, the dam plays a crucial role in protecting surrounding communities and infrastructure from potential water-related disasters, emphasizing the importance of ongoing monitoring and maintenance efforts to safeguard water resources and climate resilience in the area.

As a key feature in the flood risk reduction infrastructure, Hirsch Dam's significance lies in its contribution to water management and protection of downstream areas from potential inundation. With its historical construction and ongoing state regulation, the dam serves as a vital asset in the overall water resource management strategy in Nebraska. Its condition assessment provides valuable insights for stakeholders and decision-makers, highlighting the need for continued investment in maintenance and improvements to ensure the dam's long-term effectiveness in addressing water-related challenges in the region.
