Ryan Detention Dam, located in Solomon, Arizona, is a federal structure managed by the Bureau of Land Management and designed for flood risk reduction along the Ryan Draw river. Built in 1967, this gravity dam stands at a hydraulic height of 34 feet and a structural height of 37 feet, with a length of 2000 feet and a storage capacity of 435 acre-feet. Despite its low hazard potential and fair condition assessment, the dam has a moderate risk rating, indicating a need for ongoing monitoring and management measures.

While the dam does not fall under state regulation or jurisdiction, it is inspected every five years, with the last inspection conducted in July 2015. With an uncontrolled spillway and a surface area of 38 acres, Ryan Detention Dam serves as a crucial infrastructure for mitigating flood risks in the region. Its primary purpose and design focus on flood risk reduction, showcasing the importance of such structures in maintaining water resource sustainability and climate resilience in arid regions like Arizona.

As climate change continues to impact water resources and weather patterns, the role of dams like Ryan Detention Dam becomes increasingly vital in managing flood risks and ensuring water security for local communities. With an emphasis on risk assessment and management, as well as regular inspections and maintenance, this federal dam serves as a critical piece of infrastructure in safeguarding against the potential impacts of extreme weather events and climate variability in the region.
