Summary

Completed in 1988, the outlet plays a key role in regulating the flow of water from the Jordan River into the Great Salt Lake. With a dam height of 9 feet and a hydraulic height of 6 feet, the outlet has a storage capacity of 1,369,894 acre-feet and serves as a primary source of water supply for the region.

Although rated as having a low hazard potential, the condition assessment of Utah Lake Outlet is currently marked as "Not Rated." The structure, primarily an earth dam, spans a length of 1,100 feet and is situated in a drainage area of 3,010 square miles. While the outlet does not have spillway gates, it is subject to regular inspections by the state regulatory agency to ensure its continued functionality and safety. In case of emergencies, the outlet is equipped with an Emergency Action Plan (EAP), although details regarding its preparation and last revision date are currently unavailable.

In the realm of water resource and climate management, Utah Lake Outlet stands as a critical infrastructure supporting the water supply needs of the Utah region. Its strategic location and design make it a key component in the water distribution system, playing a crucial role in maintaining the balance of water flow between the Jordan River and the Great Salt Lake. Regular inspections and oversight by the Utah Division of Water Rights ensure that the outlet continues to operate effectively while minimizing potential risks and hazards associated with its operation.

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.
