Summary
Built in 1976 by the USDA NRCS, this Earth-type dam stands at a height of 25 feet and has a length of 153 feet. With a storage capacity of 50 acre-feet, the dam serves various purposes, primarily designated for flood control and water resource management. Despite being classified as a low-hazard structure, the dam poses a very high risk due to its location and potential impact on downstream areas.
Managed by the Oklahoma Water Resources Board, Boggess No 2 undergoes regular inspections, with the last one conducted in 2005. Although the dam's condition is currently not rated, its risk assessment is deemed very high (1) based on the potential consequences of failure. With only one valve outlet gate for water release, the controlled spillway system is designed to handle a maximum discharge of 810 cubic feet per second. Despite meeting state regulatory requirements, the dam lacks an Emergency Action Plan (EAP) and inundation maps, highlighting areas for improvement in emergency preparedness and risk mitigation.
In the event of an emergency, the lack of updated emergency contacts, EAP guidelines, and risk management measures is a concern for the safety and protection of downstream communities. As water resource and climate enthusiasts, it is essential to advocate for the implementation of necessary measures to enhance the dam's resilience and preparedness for potential risks. By addressing these gaps in emergency planning and risk management, Boggess No 2 can better safeguard against potential hazards and ensure the sustainable management of water resources in the region.

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.
