Turner, also known as Turner Lake, is a public utility water supply dam located in Escondido, California. Built in 1971, this earth dam stands at 111 feet in height with a hydraulic height of 102 feet, creating a reservoir with a storage capacity of 2000 acre-feet. The dam serves the primary purpose of providing water for irrigation and water supply in the region, drawing from the Moosa Canyon stream.

Managed by the Department of Water Resources (DWR) and subject to state regulations, Turner Dam has been assessed as having a high hazard potential but is currently in satisfactory condition. Regular inspections are conducted, with the most recent inspection in June 2020, ensuring the safety and integrity of the structure. The dam's Emergency Action Plan (EAP) is up to date, with the last revision in January 2021, demonstrating proactive measures in place to address any potential risks or emergencies.

With its vital role in water supply management for the surrounding area, Turner Dam stands as a critical infrastructure for water resource enthusiasts and climate advocates. Its strategic location in San Diego County and the Moosa Canyon drainage area highlights the importance of sustainable water management practices in the face of changing climate conditions.
