Summary

25a, located in Weber, Utah, is a Federal-owned structure managed by the Bureau of Reclamation. Built in 1949, this Earth-type dam stands at a structural height of 11.8 feet and has a storage capacity of 13 acre-feet. Situated along the Ogden River, this reservoir serves as a crucial water resource for the region, helping to regulate water flow and provide essential storage for times of need.

With a high hazard potential, South Ogden Equalizing Reservoir No. 25a is subject to regular inspections by the Bureau of Reclamation to ensure its safety and integrity. The last inspection was conducted in May 2020, with a frequency of every 4 years. While the condition assessment is currently not available, emergency action plans are in place, with the last revision made in June 2020. Despite its age, this reservoir continues to play a vital role in water management within the area, supported by federal funding and oversight.

As a key component of the water infrastructure in the region, South Ogden Equalizing Reservoir No. 25a remains a crucial asset for water resource and climate enthusiasts. Its presence along the Ogden River, combined with its strategic location and storage capacity, underscores its importance in maintaining water supply reliability and resilience in the face of changing climate conditions. With ongoing monitoring and maintenance, this reservoir continues to serve as a vital resource for the community and surrounding areas.

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.
