Summary
Standing at a height of 17 feet with a length of 860 feet, the dam has a storage capacity of 230 acre-feet and a surface area of 23 acres. Despite being an earth dam with a buttress core, it lacks a spillway and has limited discharge capabilities.
While the dam's hazard potential is labeled as "Not Available" and its condition assessment is "Not Rated," it is considered to have a high risk level (2). The structure has not been inspected recently, and its emergency action plan status, as well as risk management measures, are unknown. The absence of updated information on the dam's safety and operation highlights the need for increased monitoring and maintenance to ensure the safety of water resources in the area.
For water resource and climate enthusiasts, P Flores Lake Dam represents a significant asset for water supply in the region. However, the lack of recent inspections and risk management measures raises concerns about the structure's safety and resilience in the face of potential hazards. As the dam plays a crucial role in water management along Chico Creek, it is essential for relevant authorities to prioritize regular inspections and maintenance to mitigate risks and protect the surrounding environment and communities.

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.
