Round Rock, also known as Round Rock Lake, is a Federal-owned water resource located in Apache County, Arizona. Managed by the Bureau of Indian Affairs, this reservoir was completed in 1937 and primarily serves the purpose of irrigation. With a structural height of 40 feet and a length of 1675 feet, Round Rock has a storage capacity of 833 acre-feet, making it a crucial water source in the region.

Situated along the Lukachukai Wash, Round Rock not only supports irrigation but also serves purposes such as fire protection, stock watering, and recreation. Despite being a Federal-owned structure, Round Rock is not regulated by the state and does not require state permitting or inspection. However, the high hazard potential of the dam necessitates regular inspections, with the last one conducted in April 2012.

With a very high risk assessment rating, Round Rock poses potential risks that require proper risk management measures. Emergency action plans and guidelines are crucial to ensure the safety and security of the surrounding area in case of any dam-related emergencies. As a vital water resource in the region, Round Rock plays a significant role in water management and climate resilience efforts in Apache County, Arizona.
