Summary

Built in 1970 by the Bureau of Indian Affairs, this earth dam stands at a structural height of 29 feet and spans 500 feet in length. With a storage capacity of 70 acre-feet, the primary purpose of Upper Point of Pines is to provide recreational opportunities for visitors in the area.

Despite its age, Upper Point of Pines is considered to have a high hazard potential and a very high risk assessment rating. While the condition assessment is not available, the emergency action plan was last revised in 2013, indicating ongoing efforts to ensure the safety and security of the dam. However, the risk management measures and inundation maps for the dam are currently not prepared, highlighting potential areas for improvement in the future.

Situated within the Los Angeles District of the US Army Corps of Engineers, Upper Point of Pines serves as a vital water resource for the surrounding area. Its controlled spillway and emergency action plan further emphasize the importance of maintaining and monitoring this dam to ensure its continued functionality and safety for both recreational users and the local ecosystem.

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.
