Hinebaugh Dam, located in Garden Grove, Iowa, was completed in 1979 and is owned privately. The dam, designed by USDA NRCS, serves multiple purposes including fire protection and as a small fish pond. It stands at a height of 24 feet and has a length of 395 feet, with a storage capacity of 50 acre-feet. Situated on the TR-Weldon River, the dam is regulated by the Iowa DNR and is subject to state inspection and enforcement.

Despite its low hazard potential, Hinebaugh Dam poses a moderate risk, with a drainage area of 0.23 square miles. The spillway is uncontrolled, and the dam is primarily constructed of earth with a soil foundation. Although last inspected in 1986, the condition assessment is currently listed as "Not Rated." The risk management measures for the dam are not specified, indicating a need for further evaluation and potential updates to its emergency action plan.

For water resource and climate enthusiasts, Hinebaugh Dam presents an intriguing case study in dam regulation and management. With its unique location on the TR-Weldon River and multiple designated purposes, the dam serves as a vital infrastructure piece in the local community. However, its risk assessment and condition status warrant attention to ensure the safety and effectiveness of the structure for both current and future use.
