The dam's location, design, and purpose make it a key player in the water supply system of the region, providing essential resources for agricultural activities and contributing to the overall water management efforts in California. As climate change continues to impact water resources, structures like Turkey Ranch become increasingly important for ensuring sustainable and reliable access to water for both present and future generations.
