Summary

Completed in 1969, this earth dam stands at a structural height of 16 feet with a hydraulic height of 11 feet, helping to mitigate potential flooding in the area. With a storage capacity of 90 acre-feet and a drainage area of 53.1 square miles, the park plays a vital role in protecting the surrounding community from high hazard potential events.

Despite its critical function, the dam at Salt Lake Co-Creekside Park is currently assessed in fair condition and undergoes inspections every two years to ensure its effectiveness in flood risk reduction. The Utah Division of Water Rights oversees the regulatory aspects of the structure, enforcing state permitting, inspection, and enforcement measures. As one of the key infrastructure projects in the region, this park exemplifies the importance of proactive management and maintenance to safeguard against potential flood hazards in a climate-vulnerable area.

Located within the Omaha District, Salt Lake Co-Creekside Park serves as a testament to the ongoing efforts to manage water resources and climate risks in the face of changing environmental conditions. As a part of the broader network of flood risk reduction structures, this park not only provides protection for the community but also highlights the need for continued investment in resilient infrastructure to adapt to the challenges posed by a changing climate. With its strategic location along Big Cottonwood Creek, this park stands as a symbol of proactive adaptation and risk management in the face of increasing climate variability.

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.
