Alpine Sanitary is a privately owned offstream dam located in Apache County, Arizona. Built in 1980, this earth dam stands at a height of 9 feet with a length of 2414 feet, providing a storage capacity of 142.4 acre-feet and covering a surface area of 17.5 acres. While primarily serving purposes like fire protection and stock maintenance, it also supports other functions such as small fish ponds.

Managed and regulated by the Arizona Department of Water Resources, Alpine Sanitary has a significant hazard potential but is currently assessed as being in satisfactory condition. Regular inspections are conducted, with the last one taking place in June 2019, and the dam has an inspection frequency of 3 years. Despite its high risk assessment level, appropriate risk management measures are in place to ensure the safety and integrity of the structure in case of emergencies. For water resource and climate enthusiasts, Alpine Sanitary is a fascinating site that showcases the intersection of human infrastructure with natural ecosystems in the arid landscapes of Arizona.
