Briggs Rl dam
Briggs Rl
Briggs Rl, located in Mannford, Oklahoma, is a privately owned dam regulated by the Oklahoma Water Resources Board. 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
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Briggs Rl
Where does the data for Briggs Rl come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
