When did construction start on the All-American Canal?

Construction on the All-American Canal began in 1933. This canal was a critical infrastructure project intended to transport water from the Colorado River to irrigate agricultural lands in the Imperial Valley, California. The canal was part of a larger effort to support agriculture in the arid region and to manage water resources effectively in Southern California.

Understanding the timeline of this project is essential as it reflects the broader trends in water management and development initiatives during the early to mid-20th century in California, showcasing the state's response to both agricultural needs and population growth. The correct date is pivotal for grasping the historical context of water resource management in the region, including challenges related to water rights, engineering innovations, and environmental impacts.
