Which action did the Boulder Canyon Project Act (1928) authorize?

• A. Authorized construction of the Hoover Dam on the Colorado River and the All-American Canal to the Imperial Valley in California.
• B. Created the Tennessee Valley Authority to oversee dam construction and power generation.
• C. Authorized the construction of the Grand Coulee Dam in Washington.
• D. Granted federal authority to regulate interstate water rights.

Answer: (A)

The main idea here is federal action to control a major river system for multiple public benefits. The Boulder Canyon Project Act authorized building a large dam on the Colorado River—Hoover Dam—which would create a substantial reservoir (Lake Mead) for flood control, water storage, and hydroelectric power. It also funded the All-American Canal to deliver Colorado River water to California’s Imperial Valley, enabling reliable irrigation in a desert region. This package made possible a coordinated management plan for the lower Colorado River basin, balancing water supply, flood protection, farming needs, and electricity generation. The other options don’t fit this specific authorization. The Tennessee Valley Authority came later and involved a different river system. The Grand Coulee Dam is on the Columbia River and was authorized under a different set of laws. Granting federal authority to regulate interstate water rights is a broader power topic, not the concrete project the Boulder Canyon Act created.
