New Bass Lake, located in El Dorado Hills, California, is a local government-owned reservoir with a primary purpose of water supply. Completed in 1978, this Earth type dam stands at 26 feet tall and has a storage capacity of 745 acre-feet. The lake covers a surface area of 62 acres and is fed by Carson Creek, serving as a vital resource for irrigation, recreation, and water supply in the region.

Despite its age, New Bass Lake has a satisfactory condition assessment and a high hazard potential, requiring regular inspections and maintenance to ensure its structural integrity. The dam is regulated by the California Department of Water Resources (DWR) under the Safety of Dams program, with state jurisdiction, permitting, inspection, and enforcement in place. The last inspection in February 2021 deemed the dam to be in satisfactory condition, but its high hazard potential necessitates continued vigilance and risk management measures.

With its scenic location and importance as a water source for the community, New Bass Lake provides both recreational opportunities and essential water supply services. As a key infrastructure in the region, it underscores the intersection of water resource management and climate resilience, emphasizing the need for ongoing monitoring and maintenance to safeguard against potential risks and ensure the continued safety and reliability of this critical water storage facility.
