Summary

The dam stands at a height of 22 feet with a hydraulic height of 18 feet, spanning a length of 1250 feet and providing a storage capacity of 1056 acre-feet. Despite its low hazard potential, Pond K is subject to state regulation by the Department of Water Resources and undergoes regular inspections to ensure its structural integrity and compliance with safety standards.

Situated in Amador County, Pond K covers a surface area of 69 acres with a drainage area of 0.34 square miles. The dam is equipped with outlet gates for controlled water release, although specific details about spillway type and maximum discharge are not provided in the data. With its satisfactory condition assessment as of September 2017 and a low risk assessment, Pond K serves as a vital component of water resource management in the region, contributing to flood control and water storage for various purposes.

Managed by a private owner, Pond K serves as a crucial infrastructure for water management in the area, aligning with state regulations and inspection requirements to ensure public safety and environmental protection. With its completion in 2006 and ongoing monitoring efforts, Pond K exemplifies the intersection of engineering excellence and environmental stewardship in balancing water resource needs with climate resilience in California's diverse landscape.

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.
