Summary
This earth dam, completed in 1980, stands at a height of 51 feet and has a storage capacity of 650 acre-feet. Serving primarily as a water supply source, the dam also plays a role in flood risk reduction and irrigation in the region. The structure is regulated by the Department of Water Resources and undergoes regular inspections to ensure its safety and functionality.
With a Hazard Potential rating of high, Lakeport Dam is deemed to be in satisfactory condition as of the last assessment in September 2017. In case of emergencies, an Emergency Action Plan is in place, with the last revision made in March 2021. The dam is situated on Tr Manning Creek and falls under the jurisdiction of the state regulatory agency, ensuring that it meets all necessary permitting, inspection, and enforcement requirements. Its strategic location and purpose make it a crucial asset for water management and climate resilience efforts in the area.
Managed by the local government, Lakeport Dam is a key infrastructure contributing to the water supply, flood control, and irrigation needs of the community. With its significant storage capacity and strategic location, the dam serves as a critical resource for sustaining water security in Lakeport and surrounding areas. As climate change continues to impact water resources, the maintenance and proper regulation of structures like Lakeport Dam are essential for ensuring the resilience of water systems in the face of evolving environmental challenges.

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.
