// Strategic Significance
Theodore Roosevelt Dam on the Salt River northeast of Phoenix was the first major reclamation project in the US completed in 1911. It is the largest masonry dam in the world and a critical water supply for the Phoenix metropolitan area of 5 million people. A failure would be catastrophic for the Phoenix metro water supply and downstream communities.
// Civilian Impact Assessment
Phoenix metro with 5 million people depends on the Salt River Project for water supply. Downstream Salt River communities including Mesa and Tempe would face serious flooding risk.
// Evacuation & Shelter Guidance
Arizona Route 188, US-60. Maricopa County Emergency Management coordinates with Salt River Project for dam emergency response.
