Summary

This Earth dam stands at a height of 30 feet and has a length of 240 feet, providing a storage capacity of 5 acre-feet. While its construction year is unknown, Upper Pond's hazard potential is considered significant, making it an essential site to monitor and maintain for water resource and climate enthusiasts.

Managed by the Mine Safety and Health Administration, Upper Pond serves a primary purpose classified as "Other," with no specific details on its usage provided in the data. Despite lacking information on its condition assessment and emergency preparedness measures, this pond's location in San Mateo County highlights its importance in the local water management infrastructure. Its close proximity to the San Francisco District underscores its significance in the region's water resource network.

For water resource enthusiasts interested in exploring infrastructure projects like Upper Pond, this site offers a unique opportunity to study private dam structures and their impact on local water systems. With a focus on the significant hazard potential and limited regulatory oversight, understanding and monitoring Upper Pond's condition is crucial for ensuring the safety and sustainability of its operations in the face of changing climate patterns and water resource management 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. 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.
