Summary
Completed in 1978, this earth dam stands at a height of 25 feet and has a storage capacity of 361 acre-feet, providing water for agricultural needs in the region. The dam is situated on the TR-SOUTH FORK SALT RIVER and is owned privately, with no state jurisdiction or regulation.
Despite its importance in supporting local irrigation needs, Lierheimer Lake Dam poses a high hazard potential due to its condition being rated as "Not Rated." With no recent inspection data available, there is a need for regular monitoring and assessment to ensure the safety and reliability of the structure. The dam's emergency action plan status and risk management measures are also unspecified, highlighting the importance of proactive risk assessment and management in safeguarding the surrounding community and environment from potential hazards.
As a key feature in the water infrastructure of the area, Lierheimer Lake Dam warrants attention and investment to enhance its safety and operational efficiency. With its strategic location and vital role in irrigation, efforts to update inspection data, implement emergency action plans, and assess risk factors will be crucial in ensuring the long-term sustainability and resilience of this essential water resource.

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.
