In which year did the Los Angeles Aqueduct begin service?

The Los Angeles Aqueduct began service in 1913, making this the correct answer. This critical infrastructure was designed to transport water from the Owens Valley to the city of Los Angeles, fulfilling the growing demands for water in an urban area that was rapidly expanding at the time. The completion of the aqueduct played a pivotal role in the development and sustainability of Los Angeles, allowing the city to thrive in an arid climate. The project's significance also sparked discussions and debates about water rights, control, and environmental impact, themes that continue to resonate in California's water management discussions today. Such historical milestones are crucial for understanding California's complex water issues and the evolution of its water supply strategies.
