Lakeport dam
Lakeport
Lakeport, located in Lake County, California, is home to a vital water resource known as Lakeport Dam. 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.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Lakeport
Where does the data for Lakeport come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the High hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
