Summary

With a primary purpose of recreation, this masonry dam stands at a height of 10.8 feet and has a storage capacity of 300 acre-feet. The dam has a low hazard potential and is not currently rated in terms of condition assessment.

Despite being a local government-owned structure, Warwick Dam is regulated and permitted by the North Dakota State Water Commission (NDSWC). The dam has undergone modifications in 1955 to reinforce its foundation. It is situated within the Omaha District of the US Army Corps of Engineers and is not equipped with a spillway system. The risk assessment for Warwick Dam indicates a high risk level, warranting close monitoring and potential risk management measures in the future.

Warwick Dam, with its picturesque setting and significant historical value, remains a popular spot for outdoor enthusiasts and nature lovers. While its risk level may pose challenges, the dam continues to be a resilient structure that plays a crucial role in water resource management and recreational activities in the region. Ongoing inspections and regulatory oversight by the NDSWC ensure the safety and stability of Warwick Dam for both visitors and the surrounding environment.

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.
