Summary
This private dam stands at 15 feet tall with a length of 1380 feet, creating a reservoir with a storage capacity of 192 acre-feet. Despite its age, the dam's condition remains unrated, posing a high risk with limited risk management measures in place.
The dam, built for water supply purposes, is made of earth and buttress core types, with no spillway present. The structure overlooks TR-REISER CREEK and is regulated by the state with permitting and inspection processes in place. Quiros Lake Dam's emergency preparedness, including the existence of an Emergency Action Plan (EAP), has not been updated or assessed, highlighting potential vulnerabilities in the event of a hazard.
Given its critical role in water management, Quiros Lake Dam's risk assessment and management should be a top priority for stakeholders. With its location in a high-risk area and no designated emergency contacts or inundation maps prepared, proactive measures must be taken to ensure the dam's safety and functionality in the face of climate challenges and potential emergencies.

Dam Data Reference
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.
