Big Sage Reservoir, located in Modoc County, California, is a vital water resource serving the community of Canby. Built in 1921, this earth dam stands at a height of 49 feet and has a storage capacity of 77,000 acre-feet, primarily used for irrigation and water supply purposes. The reservoir covers a surface area of 5,270 acres and is fed by Rattlesnake Creek, providing a crucial source of water for the region.

Managed by a public utility, Big Sage Reservoir is regulated by the California Department of Water Resources and undergoes regular inspections to ensure its safety and functionality. With a high hazard potential but a satisfactory condition assessment as of September 2017, the reservoir plays a critical role in water management in the area. Despite its age, the dam continues to meet guidelines and remains a key component of the water supply infrastructure in the region.

As climate change continues to impact water resources, the management and upkeep of structures like Big Sage Reservoir become increasingly important. With its historical significance and essential role in water supply, the reservoir serves as a reminder of the ongoing need to adapt and maintain infrastructure to meet the challenges of a changing climate and growing water demand in California.
