Summary

With a height of 26 feet and a length of 530 feet, the dam provides a storage capacity of 166 acre-feet and covers a surface area of 16 acres. The dam's spillway, with a width of 60 feet, is uncontrolled, and it has a maximum discharge capacity of 1413 cubic feet per second.

Despite being privately owned, Laguna Palma Dam is considered to have a high hazard potential due to its age and condition, which is currently rated as "Not Rated." The dam has not been inspected since May 1979, and it is categorized as having a moderate risk level. While the dam does not fall under state jurisdiction or regulation, its impact on the surrounding environment and community highlights the importance of regular maintenance and monitoring to ensure public safety and water resource sustainability in the area. Enthusiasts of water resources and climate change should keep an eye on developments regarding the maintenance and management of Laguna Palma Dam to safeguard against potential risks and ensure its continued recreational use for future generations.

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. 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

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, 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.
