Fort Gibson Dam - Dike 11 dam
Fort Gibson Dam - Dike 11
Fort Gibson Dam - Dike 11, located in Fort Gibson, Oklahoma, is a federal-owned structure managed by the US Army Corps of Engineers. Completed in 1949, this gravity dam stands at 110 feet tall and spans 2990 feet across the Grand River, serving primarily for flood risk reduction purposes. With a storage capacity of 1,284,400 acre-feet and a maximum discharge of 986,000 cubic feet per second, the dam plays a crucial role in managing water levels and preventing flood damage downstream.
Despite its high hazard potential, Fort Gibson Dam is equipped with a controlled spillway and emergency action plan to mitigate risks and ensure public safety. The US Army Corps of Engineers regularly inspects and maintains the dam, collaborating with local emergency managers to enhance preparedness and response capabilities in case of a dam-related emergency. By implementing risk management measures and monitoring the dam's condition, the USACE aims to minimize the impact of severe weather events and maintain the structural integrity of the dam for the surrounding community.
As an essential component of water resource management in Oklahoma, Fort Gibson Dam - Dike 11 underscores the importance of proactive risk assessment and effective emergency planning to safeguard against potential flooding threats. With ongoing efforts to address flood risks and engage stakeholders in emergency preparedness, the US Army Corps of Engineers remains committed to ensuring the resilience and functionality of this critical infrastructure.

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 - Dike 11
Where does the data for Fort Gibson Dam - Dike 11 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.
