Which policy initiative opened western lands for settlement and promoted water management in the Southwest?

• A. The Reclamation Act
• B. The Antiquities Act
• C. The Mann-Elkins Act
• D. The National Park Service Organic Act

Answer: (A)

Opening western lands for settlement and managing water in the Southwest was achieved through the Reclamation Act. This policy redirected federal resources to fund irrigation projects by selling public lands, with the proceeds used to build canals, ditches, and other waterworks. The goal was to transform arid western lands into productive farmland, making settlement feasible in the Southwest and creating a lasting federal role in water management through the Bureau of Reclamation. The other acts address different aims—protecting archaeological sites, regulating railroads and tariffs, or organizing the National Park Service—so they don’t focus on opening lands or promoting irrigation and settlement the way this act does.
