Hruby Dam, located in Valley, Nebraska, was completed in 1974 by the USDA NRCS and serves multiple purposes including fire protection, livestock watering, and a small fish pond. With a dam height of 11.6 feet and a storage capacity of 147.7 acre-feet, the earth dam also helps regulate flow on Cottonwood Creek. The dam's primary owner is private, but it is state-regulated by the Nebraska Department of Natural Resources.

Despite its low hazard potential and fair condition assessment, Hruby Dam is subject to regular state inspections and enforcement to ensure its safety and functionality. The dam spans 326 feet in length and covers a surface area of 20.2 acres, providing essential water resources for the surrounding area. Its location in the Omaha District and proximity to Arcadia make it a vital part of the local ecosystem and water management infrastructure.
