Summary
Constructed in 1967, this earth dam reaches a height of 23 feet and has a storage capacity of 160 acre-feet. With a normal storage level of 78 acre-feet and a drainage area of 130 square miles, the dam plays a vital role in regulating water flow and protecting the surrounding area from potential hazards.
Managed by a private entity, the Duce Lake Dam is not regulated by the state and has a high hazard potential due to its condition assessment being labeled as "not rated." Despite its critical role in debris control, fire protection, and stock maintenance, the dam lacks certain safety features such as a spillway and outlet gates. With limited information available on emergency preparedness measures and risk assessments, there is a need for further evaluation and potential upgrades to ensure the safety and sustainability of this essential water resource infrastructure.
As water resource and climate enthusiasts continue to monitor and advocate for the protection of our natural assets, the Duce Lake Dam serves as a reminder of the importance of maintaining and improving our infrastructure to withstand potential challenges posed by climate change and increasing water demands. With its unique design and historical significance, the dam presents both opportunities and challenges for sustainable water management in the region, calling for collaborative efforts and innovative solutions to ensure its long-term functionality and resilience.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
