Summary
Built in 1962 by the USDA NRCS, this earth dam stands at a height of 26 feet and has a hydraulic height of 18 feet, designed primarily for flood risk reduction on the Salopek Arroyo. With a storage capacity of 71.25 acre-feet and a drainage area of 0.7 square miles, the dam has a significant hazard potential and is currently assessed to be in poor condition.
The dam features an uncontrolled spillway with a width of 100 feet and has no outlet gates. Despite being regulated and inspected by the Office of the State Engineer, the dam's condition assessment in November 2020 indicated poor maintenance, highlighting the need for risk management measures to address its moderate risk level. The structure is closely monitored due to its significant hazard potential, and emergency action plans are essential for ensuring the safety of nearby residents in case of a breach. For water resource and climate enthusiasts, Fillmore Site 2 Dam serves as a vital infrastructure for flood protection in the region, reflecting the importance of proper maintenance and risk assessment for managing water resources effectively.

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.
