Magalia, located in Butte County, California, is home to a crucial water supply dam known as Magalia Dam. Completed in 1918, this earth dam stands at a height of 103 feet and has a hydraulic height of 89.3 feet, providing a storage capacity of 2900 acre-feet. The dam serves the primary purpose of water supply for irrigation and other uses in the region, drawing water from the Little Butte Creek.

Despite its historical significance and essential function, Magalia Dam poses a high hazard potential and has been assessed to be in poor condition as of March 2019. The dam is regulated by the California Department of Water Resources (DWR) and undergoes regular inspections to ensure its safety and compliance with state regulations. With a distance of 15 miles from the city of Chico and under the jurisdiction of the state, Magalia Dam plays a crucial role in managing water resources in the area and mitigating potential risks associated with its operation. Climate and water resource enthusiasts are encouraged to stay informed about the maintenance and management of Magalia Dam to support sustainable water management practices in the region.
