Summary

This rockfill dam, completed in 1937, stands at a hydraulic height of 103 feet and has a structural height of 137 feet, with a storage capacity of 116,150 acre-feet. The reservoir covers an area of 2,874 acres and is fed by the Ogden River, serving as a key source of water for the surrounding area.

In recent years, Pineview Reservoir has undergone multiple modifications to enhance its structural and seismic stability, with updates in 1993 and 2004. The reservoir has a controlled spillway with a width of 24 feet, and it is subject to regular inspections due to its high hazard potential. Despite its risk assessment rating of "Very High (1)", Pineview Reservoir continues to provide essential water storage and management for the region, ensuring the sustainability of water resources in Weber County, Utah.

With its significant storage capacity and strategic location along the Ogden River, Pineview Reservoir plays a crucial role in water management and irrigation in the area. As a federal-owned and regulated structure, it is operated and maintained by the Bureau of Reclamation, ensuring the safety and reliability of this essential water resource for the community. The reservoir's continuous monitoring and risk management measures underscore its importance in safeguarding water supply and addressing the challenges posed by climate change and water resource management in the region.

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.
