Jim O'Kief Dam, located in Niobrara, Nebraska, is a private-owned structure designed by USDA NRCS for the primary purpose of serving as a Fish and Wildlife Pond. This Earth-type dam, completed in 1956, stands at a height of 24 feet and has a structural height of 32 feet, with a storage capacity of 2754 acre-feet. The dam is situated on the South Fork of Fairfield Creek and covers a surface area of 8 acres, with a drainage area of 17.8 square miles.

In 1999, the dam underwent structural modifications to ensure its continued safety and functionality, with the last inspection conducted in May 2019, revealing a satisfactory condition assessment and low hazard potential. The dam is regulated by the Nebraska Department of Natural Resources and meets state permitting, inspection, and enforcement requirements. Despite its relatively low risk profile, ongoing maintenance and potential repair work may be necessary in the future to uphold the dam's integrity and ensure its continued effectiveness in supporting local wildlife and habitat conservation efforts.

Water resource and climate enthusiasts interested in the preservation of essential ecosystems and wildlife habitats in Nebraska will find the Jim O'Kief Dam (Repair) project particularly intriguing. With its focus on providing a sustainable environment for fish and wildlife, this dam serves as a vital component of the local ecosystem, offering valuable storage capacity and flood control measures. As discussions surrounding climate change and water resource management continue to gain traction, the upkeep and maintenance of structures like the Jim O'Kief Dam play a crucial role in safeguarding the natural environment and supporting biodiversity in the region.
