Fort Gibson Dam - Dike 3 dam
Fort Gibson Dam - Dike 3
Fort Gibson Dam - Dike 3, also known as Fort Gibson Lake, is a gravity-type dam located in Fort Gibson, Oklahoma. Built in 1949 by the US Army Corps of Engineers, this dam serves the primary purpose of flood risk reduction along the Grand River. With a height of 110 feet and a length of 2990 feet, it has a storage capacity of 1,284,400 acre-feet and a normal storage volume of 365,200 acre-feet. The dam has a spillway width of 1490 feet and a maximum discharge capacity of 986,000 cubic feet per second.
The dam is classified as high hazard potential with a very high risk assessment rating, indicating the potential for significant flooding events. The US Army Corps of Engineers manages the dam-related flood risks by monitoring its condition, prioritizing risk-reduction activities, and collaborating with local emergency managers to raise awareness and develop emergency response plans. The dam releases water to manage water levels and relieve pressure, but severe weather events can overwhelm the system. Regular maintenance and repairs are conducted to ensure the dam's structural integrity and functionality, with continual updates to the emergency action plan to enhance preparedness and response efforts.
Overall, Fort Gibson Dam - Dike 3 plays a crucial role in flood risk mitigation and water management in the region, highlighting the importance of proactive risk management and collaboration between agencies and communities to ensure the safety and resilience of water resources in the face of potential emergencies.

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 3
Where does the data for Fort Gibson Dam - Dike 3 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.
