Summary

This private-owned dam, primarily used for recreational purposes, boasts an impressive earth structure with a hydraulic height of 16 feet and a storage capacity of 324 acre-feet. With a low hazard potential and moderate risk assessment rating, the dam plays a crucial role in regulating water flow and mitigating potential risks in the surrounding area.

Despite not being state-regulated, Amlajack Lake Dam undergoes regular inspections to ensure its structural integrity and safety. The dam's uncontrolled spillway and outlet gates add to its unique design, allowing for controlled water release when necessary. With a drainage area of 651 square miles and a surface area of 28 acres, the dam serves as a vital component in the local ecosystem, providing not only recreational opportunities but also essential water storage for the region.

As climate change continues to impact water resources and infrastructure, Amlajack Lake Dam serves as a model for sustainable dam management and risk mitigation. Its strategic location, design features, and regular maintenance highlight the importance of proactive measures in safeguarding water resources and adapting to changing climate conditions. For water resource and climate enthusiasts, Amlajack Lake Dam stands as a symbol of resilience and innovation in the face of environmental 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.
