The Lemoore Diversion Weir, located on the Kings River in Hardwick, California, is a vital structure designed to reduce flood risks in the region. Completed in 1924, this buttress-type dam stands at 21 feet in height and spans 192 feet in length, providing a storage capacity of 50 acre-feet. Despite its age, the weir has been well-maintained and is deemed to have low hazard potential with a satisfactory condition assessment as of September 2017.

Managed by a private owner, the Lemoore Diversion Weir is regulated by the California Department of Water Resources and falls under the jurisdiction of the state for permitting, inspection, and enforcement. With a primary purpose of flood risk reduction, the weir also serves irrigation needs in the area. The Sacramento District of the US Army Corps of Engineers oversees the operation and maintenance of this crucial infrastructure, ensuring its continued effectiveness in protecting the surrounding communities from potential flooding events.

Although the Lemoore Diversion Weir has not undergone recent modifications or risk assessments, its key role in flood management along the Kings River underscores its significance in safeguarding the local environment and economy. With its strategic location and historical importance, this structure represents a longstanding commitment to water resource management and climate resilience in the region.
