Summary
Built in 1970, this structure stands at a height of 20 feet and has a maximum storage capacity of 85 acre-feet. The primary purpose of Nickel B is categorized as 'Other', with a spillway type of 'Controlled' and a hazard potential rated as 'Low'. Despite its low hazard potential, the risk assessment for this dam is considered 'Very High (1)', indicating the need for careful monitoring and management.
The dam's location near the TR-CADDO CR river in the city of Double Springs Ch. highlights its crucial role in water resource management in the region. With a maximum discharge capacity of 1736 cubic feet per second, Nickel B plays a vital role in flood control and water supply for the area. Although the dam has not been rated for its condition assessment, regular inspections have taken place with a frequency of every 5 years.
Managed by the Oklahoma Water Resources Board (OWRB), Nickel B is subject to state regulation and permitting, ensuring that it meets necessary safety standards. The dam's association with other structures is minimal, with only one valve outlet gate identified. As a significant contributor to the region's water infrastructure, Nickel B stands as a testament to the importance of proper dam maintenance and risk management in the face of changing climate conditions.

Condition Assessment
SatisfactoryNo 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
HighDams 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.
