Summary

This earth dam, completed in 1961, stands at a height of 14 feet and has a storage capacity of 140 acre-feet. With a normal storage capacity of 106 acre-feet and a surface area of 16 acres, the reservoir plays a crucial role in meeting the water needs of the area.

Managed by the local government, Warren Reservoir Upper is regulated by the state and undergoes regular inspections to ensure its structural integrity and safety. The dam has a significant hazard potential and a spillway width of 100 feet to manage maximum discharge levels. While not currently rated for its condition assessment, the reservoir remains an essential infrastructure for water resource management in the region, emphasizing the importance of sustainable water supply practices in the face of changing climate conditions.

As climate change impacts become more pronounced, the maintenance and management of Warren Reservoir Upper will be crucial in ensuring water security for the community. With the potential for increased extreme weather events and changing precipitation patterns, the resilience and adaptability of this reservoir will be key in meeting the water supply needs of the area. As such, continued monitoring, inspection, and risk assessment measures will be essential to safeguard this critical water resource and mitigate potential hazards in the face of a changing climate.

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.
