Selvage #2 is a private water supply dam located in Gilroy, California, along the Tr Llagas Cr river. It was completed in 1948 and stands at a height of 42 feet, with a hydraulic height of 36 feet and a length of 440 feet. The dam has a storage capacity of 24 acre-feet and serves primarily for irrigation and water supply purposes in the area.

Despite its low hazard potential, Selvage #2 is currently rated as being in poor condition, with its last inspection conducted in March 2021. The dam is regulated by the California Department of Water Resources (DWR) under the Safety of Dams program, ensuring that it meets state permitting, inspection, and enforcement requirements. While the dam's emergency action plan (EAP) status is unknown, measures for risk assessment and management are yet to be determined.

The structure's association with the Natural Resources Conservation Service and its location in Santa Clara County make Selvage #2 an important site for water resource and climate enthusiasts to monitor. With its historical significance dating back over 70 years, the dam's current condition and regulatory oversight offer valuable insights into the management of water resources in California.
