Summary
Constructed in 1965, this Earth-type dam spans 750 feet in length and rises 43 feet high, serving the primary purpose of water supply along the TR-Adams Creek. With a storage capacity of 1424 acre-feet, the dam features a controlled spillway and a valve outlet gate, ensuring water management and control during peak discharge events.
Maintained by the Oklahoma Water Resources Board, the New Beggs dam boasts a satisfactory condition assessment despite its high hazard potential, with regular inspections conducted every three years to ensure structural integrity and safety. The dam's location in the Tulsa District and its proximity to the city of Beggs make it a crucial asset for water resource management in the region. Representative Markwayne Mullin oversees the area's congressional interests, emphasizing the importance of climate resilience and sustainable water infrastructure.
As climate change impacts continue to threaten water resources, the New Beggs dam stands as a critical infrastructure for securing reliable water supply in Okmulgee County. With a very high risk assessment ranking, the dam's operations and emergency preparedness are essential in mitigating potential hazards and ensuring public safety. As water resource enthusiasts monitor the dam's condition and regulatory compliance, the New Beggs structure remains a cornerstone in the region's water management efforts, highlighting the intersection of climate resilience and sustainable water infrastructure.

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.
