Summary

Managed by the Utah Division of Water Rights, this earth dam stands at a hydraulic height of 10 feet and a structural height of 9 feet. Completed in 1986, it provides a storage capacity of 82 acre-feet, with a normal storage level of 44 acre-feet. With a drainage area of 23 square miles, the Falcon Db dam plays a significant role in mitigating flood hazards in the region.

Despite its importance in flood risk management, the condition of the Falcon Db dam has not been rated, and its emergency action plan (EAP) status remains unclear. The last inspection in June 2020 revealed a significant hazard potential associated with the structure. With an inspection frequency of 3 years, there is a need for regular monitoring and maintenance to ensure the safety and functionality of the dam. As a vital infrastructure owned by Sandy City, the Falcon Db dam requires ongoing attention to uphold its flood risk reduction capabilities and protect surrounding communities.

As water resource and climate enthusiasts, understanding the significance of structures like the Falcon Db dam is crucial for managing the impact of extreme weather events and ensuring the resilience of our water infrastructure. With its strategic location in Sandy City and role in flood risk reduction, the Falcon Db dam stands as a testament to the importance of proactive water management in the face of changing climate patterns. By staying informed and engaged in the maintenance and monitoring of such critical infrastructure, we can work towards a more sustainable and secure water future for all.

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.
