Summary
These evaporation ponds were completed in 1983 and have a storage capacity of 3225 acre-feet, serving the primary purpose of managing water in the Sevier River offstream. The ponds have a low hazard potential and are not currently rated for their condition.
Managed by a private entity, the Intermountain Power Evaporation Ponds play a crucial role in water resource management in the region, with state jurisdiction, permitting, inspection, and enforcement in place to ensure compliance with regulations. The ponds' location in Delta, Utah, demonstrates their significance in the local water infrastructure, contributing to the overall water management efforts in the area. With a structural height of 25 feet, these earth-type ponds provide a sustainable solution for water storage and evaporation needs.
Despite their low hazard potential, the Intermountain Power Evaporation Ponds undergo regular inspections every five years to maintain their operational integrity. The ponds stand as a testament to efficient water management and conservation efforts, meeting guidelines for emergency preparedness and risk assessment. As a critical component of the local water infrastructure, these evaporation ponds showcase the importance of sustainable water resource management in the face of climate challenges and changing environmental conditions.

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.
