Summary
Completed in 1960, this earth dam stands at 28 feet high and spans 400 feet in length. With a storage capacity of 110 acre-feet, it serves as a crucial structure for managing water resources along the TR-Rocky Canyon Creek.
Despite its low hazard potential, Briggs Rl is categorized as having a very high risk due to its age and the lack of recent condition assessments. The dam features a controlled spillway and a single valve outlet gate. While it has not been rated for its current condition, the dam is inspected every five years to ensure its structural integrity and safety. With its location in Creek County, Oklahoma, Briggs Rl plays a vital role in water resource management and flood control in the region.
As a key part of the infrastructure in the Tulsa District, Briggs Rl serves a primary purpose of water management and contributes to the overall water supply in the area. The dam's association with the TR-Rocky Canyon Creek underscores its importance in regulating water flow and mitigating flood risks. With ongoing regulatory oversight and inspection, Briggs Rl continues to play a critical role in maintaining the safety and sustainability of water resources in Oklahoma.

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.
