Alpine is a gravity dam located in Pt. Reyes Station, Marin County, California, along the Lagunitas Creek. Completed in 1917, this dam stands at a height of 143 feet and has a hydraulic height of 135 feet, serving primarily for flood risk reduction. With a storage capacity of 8892 acre-feet and a surface area of 224 acres, Alpine plays a critical role in water management in the region.

Managed by a public utility agency, Alpine is regulated, permitted, inspected, and enforced by the California Department of Water Resources (DWR) and the Safety of Dams agency. The dam has a high hazard potential but is currently assessed to be in satisfactory condition as of September 2017. With a regular inspection frequency and emergency action plan (EAP) in place, Alpine ensures public safety and environmental protection in the face of potential risks.

Alpine's presence highlights the importance of infrastructure in safeguarding communities against floods and ensuring a stable water supply. Its role in flood risk reduction, coupled with its historical significance and ongoing maintenance efforts, underscores the critical intersection of water resource management and climate resiliency in the Alpine region.
