Summary
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.

Dam Data Reference
Condition Assessment
SatisfactoryNo existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
Fair
No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
Poor A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency. Investigations and studies are necessary.
Unsatisfactory
A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
Not Rated
The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
Significant
Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environment damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
Low
Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
Undetermined
Dams for which a downstream hazard potential has not been designated or is not provided.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
