Summary
Built in 1979, the dam stands at a height of 26 feet and has a storage capacity of 57 acre-feet. While the dam is primarily used for purposes other than flood control or water supply, it plays a crucial role in regulating water flow and managing the surrounding drainage area.
Despite its low hazard potential, Shotwell No 7 has been designated as a high-risk structure due to its very high risk assessment rating. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state regulations, inspections, and enforcement. With a controlled spillway and one outlet gate, the dam is equipped to handle a maximum discharge of 790 cubic feet per second, ensuring the safety of downstream areas in case of emergencies.
Although Shotwell No 7 has not been rated for its condition assessment, it is inspected every five years to ensure its structural integrity and functionality. The dam's risk management measures and emergency action plans are not publicly available, but its location within a high-risk area necessitates careful monitoring and maintenance to prevent any potential disasters. For water resource and climate enthusiasts, Shotwell No 7 serves as a reminder of the importance of proper dam management and the critical role these structures play in mitigating risks associated with water control and storage.

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.
