Summary

Constructed in 1982, this earth dam stands at a height of 32 feet with a hydraulic height of 26 feet, providing a storage capacity of 46 acre-feet. The dam plays a significant role in water resource management, supporting the state-regulated and state-jurisdictional water rights under the Utah Division of Water Rights.

Owned and operated by a local government entity, Jordan Valley Water Purification Lower undergoes regular inspections and enforcement to ensure its structural integrity and operational efficiency. With a hazard potential classified as significant, the dam is monitored closely, with the last inspection conducted in October 2020. Despite not having a current condition assessment, the dam continues to serve its primary purpose of water supply, contributing to the sustainability and resilience of the surrounding communities in the face of changing climate conditions.

Situated in an offstream location along the Jordan River, this water purification facility demonstrates the importance of reliable water infrastructure in meeting the growing demand for clean water resources in Utah. As climate change impacts water availability and quality, the Jordan Valley Water Purification Lower stands as a vital asset in safeguarding the region's water supply and ensuring a sustainable future for generations to come.

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.
