Speas Dam, located in Sioux County, Nebraska, stands as a vital structure designed by the USDA NRCS in 1952 for fire protection, stock, and small fish pond purposes. This Earth-type dam, with a height of 37 feet and a length of 255 feet, serves to store water for various needs while also ensuring the safety of the surrounding area. Unfortunately, the dam's condition assessment in 2017 revealed poor conditions, highlighting the need for maintenance and potential improvements to ensure its longevity and effectiveness.

Owned privately and regulated by the Nebraska Department of Natural Resources, Speas Dam plays a crucial role in managing the Little Cottonwood Creek's water resources. With a normal storage capacity of 14 acre-feet and a maximum discharge of 250 cubic feet per second, the dam provides essential water supply for agricultural and wildlife purposes in the region. Despite its low hazard potential, ongoing inspections and maintenance efforts are necessary to uphold the dam's structural integrity and prevent any potential risks or hazards to the community.

As water resource and climate enthusiasts, the significance of Speas Dam lies in its contribution to water management and conservation efforts in Nebraska. By understanding and addressing the dam's current condition and maintenance needs, stakeholders can ensure the sustainable use of water resources for fire protection, livestock, and environmental purposes. As such, continued monitoring and investment in the upkeep of Speas Dam are essential to safeguarding its functionality and resilience in the face of changing climate conditions and evolving water resource demands.
