Greenbriar Management Co. Lake Dam dam
Greenbriar Management Co. Lake Dam
Greenbriar Management Co. Lake Dam, located in Moore, Oklahoma, is a privately owned structure designed for flood risk reduction on a tributary to the Canadian River. Completed in 1970, this earth dam stands at a height of 24 feet and has a length of 1270 feet, providing a maximum storage capacity of 400 acre-feet. With a controlled spillway and one outlet valve, the dam has a very high risk assessment rating due to its potential hazard, although its condition assessment is currently not rated.
Managed by the Oklahoma Water Resources Board, the Greenbriar Management Co. Lake Dam undergoes state regulation, permitting, inspection, and enforcement to ensure its structural integrity and functionality. Despite being a privately owned dam, it plays a crucial role in mitigating flood risks in the area and protecting downstream communities. The dam's undetermined hazard potential highlights the importance of continuous monitoring and maintenance to prevent any potential disasters.
With a risk management plan still undetermined and emergency preparedness measures not fully in place, the Greenbriar Management Co. Lake Dam serves as a vital flood control structure in Cleveland County, Oklahoma. As climate change continues to impact water resources and weather patterns, the importance of maintaining and upgrading such infrastructure to meet evolving challenges becomes increasingly apparent. The dam's strategic location and design play a key role in protecting the surrounding area from floods and ensuring the safety of the community.

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 Greenbriar Management Co. Lake Dam
Where does the data for Greenbriar Management Co. Lake Dam 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 Undetermined 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.
