Quail, also known as the Peace Valley Pipeline Intake, is a crucial water resource infrastructure in California's Los Angeles County. Managed by the state, this water supply structure serves the primary purpose of providing water for both hydroelectric and general water supply needs. Completed in 1981, Quail is an Earth-type dam standing at 50 feet tall, with a hydraulic height of 37 feet and a structural height of 42 feet. With a storage capacity of 8,613 acre-feet and a normal storage level of 7,440 acre-feet, Quail plays a vital role in managing water resources in the region.

Located in the city of Piru, Quail is situated along the West Branch of the CA Aqueduct. Its high hazard potential and risk assessment classification of "High (2)" underscore the importance of proper maintenance and oversight. While the condition assessment is currently listed as "Not Available," regular inspections by the Federal Energy Regulatory Commission ensure its operational integrity. With no spillway, Quail relies on its design and structural features to manage water flow effectively. The presence of associated structures or locks is not applicable, emphasizing the simplicity and efficiency of this essential water supply infrastructure.

As a key component of the water management system in the region, Quail serves as a critical link in ensuring reliable water supply and supporting hydroelectric operations. With a significant storage capacity and strategic location, it plays a vital role in meeting the water needs of the surrounding communities. Despite its high hazard potential, ongoing inspections and risk management measures by regulatory agencies help maintain the safety and effectiveness of this essential water resource infrastructure.
