Lone Pine is a key flood risk reduction structure located in Schoens Dam, Navajo, Arizona. Built in 1936, this earth dam stands at a height of 98 feet and spans 900 feet in length, with a storage capacity of 14,700 acre-feet along Show Low Creek. Despite its low hazard potential, Lone Pine plays a crucial role in safeguarding the surrounding area from potential flooding events, with a maximum discharge capacity of 15,000 cubic feet per second.

Managed by the Arizona Department of Water Resources, Lone Pine undergoes regular inspections to ensure its structural integrity and functionality. The dam's satisfactory condition assessment in 2015 highlights its reliability in flood risk mitigation. With a moderate risk assessment rating, this structure is equipped with uncontrolled spillways and a spillway width of 360 feet to manage excess water flow effectively. In the event of an emergency, the dam's risk management measures are in place to mitigate potential hazards and ensure public safety.

Water resource and climate enthusiasts can appreciate the role of Lone Pine in protecting the community from flooding and maintaining water storage capacity in the region. As a vital piece of infrastructure in Arizona's water management system, this earth dam exemplifies the importance of proactive risk assessment and maintenance to ensure the continued safety and efficiency of water resource structures.
