Summary

Completed in 1929, this earth dam stands at a height of 20 feet and has a hydraulic height of 19 feet, holding a storage capacity of 100 acre-feet. Situated on the Red Pine Fork of the Little Cottonwood River, this dam is regulated by the Utah Division of Water Rights and undergoes regular inspections, although its condition has been assessed as poor with a high hazard potential.

Despite its age and condition, Red Pine remains a critical water resource infrastructure in the region, serving agricultural irrigation needs in the area. The dam has a history of modifications and maintenance, with a last inspection date in July 2020 and a designated inspection frequency of once per year. With its significant storage capacity and location in a high-risk area, the dam's risk assessment and emergency preparedness measures are essential for ensuring the safety and efficiency of its operations.

As a key component of the local water management system, Red Pine plays a vital role in the distribution of water resources in the region, highlighting the importance of continued monitoring, maintenance, and risk management strategies. With its historical significance and ongoing regulatory oversight, the dam serves as a critical piece of infrastructure for sustaining agricultural activities and water supply reliability in the Salt Lake, Utah area.

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.
