Haiwee, also known as South Haiwee Reservoir, is a vital water resource located in Inyo, California. This local government-owned dam was completed in 1913 and serves primarily for water supply purposes, including irrigation and domestic use. Situated on the Rose Valley river stream, Haiwee boasts a storage capacity of 60,600 acre-feet and covers a surface area of 1,350 acres.

With a dam height of 81 feet and a hydraulic height of 67 feet, Haiwee poses a high hazard potential but is currently in fair condition as assessed in 2017. The dam is regulated, permitted, inspected, and enforced by the California Department of Water Resources (DWR) and Safety of Dams. Notably, the dam is located in close proximity to the city of Dunmovin and is represented by Congressman Paul Cook (R). Despite its age, Haiwee remains a crucial component of California's water infrastructure, supporting the region's agricultural and residential water needs.

As a key element in the Los Angeles District's water management system, Haiwee plays a critical role in ensuring a stable water supply for the surrounding communities. Its historical significance, coupled with its continued operation and maintenance, highlights the importance of sustainable water resource management in the face of changing climate conditions. Enthusiasts of water resources and climate resilience can appreciate Haiwee as a testament to human ingenuity in harnessing and conserving precious water resources for future generations.
