Fort Gibson Dam - Oklahoma Ordinance Works Levee dam
Fort Gibson Dam - Oklahoma Ordinance Works Levee
The Fort Gibson Dam - Oklahoma Ordinance Works Levee, also known as Fort Gibson Lake, is a gravity dam located in Mayes, Oklahoma that was completed in 1949 by the US Army Corps of Engineers. The primary purpose of this structure is flood risk reduction along the Grand River, with a total storage capacity of 1,284,400 acre-feet and a normal storage capacity of 365,200 acre-feet. The dam is 23 feet high and 5,450 feet long, with a surface area of 19,900 acres and a drainage area of 12,494 square miles.
Despite the risk associated with levees, a 2015 risk assessment classified the Oklahoma Ordnance Works Levee System as having a moderate level of risk. The primary concern is water seepage along conduits within the levee, which could lead to erosion and potential breaches causing flooding in nearby industrial and commercial buildings. To manage and mitigate this risk, the US Army Corps of Engineers has implemented several measures such as replacing metal pipes with concrete ones, conducting maintenance work on the levee slopes, and regularly updating the Emergency Action Plan. Additionally, emergency exercises are conducted with local and state responders to improve evacuation planning and response actions during flooding events.

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 Fort Gibson Dam - Oklahoma Ordinance Works Levee
Where does the data for Fort Gibson Dam - Oklahoma Ordinance Works Levee 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 High 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.
