Keystone Dam - Cleveland Levee dam
Keystone Dam - Cleveland Levee
Keystone Dam, also known as the Keystone Dam - Cleveland Levee, is a gravity dam situated on the Arkansas River in Oklahoma. Completed in 1964, this federal-owned structure serves as a crucial flood risk reduction measure, with a height of 121 feet and a length of 4600 feet. Managed by the US Army Corps of Engineers, the dam has a high hazard potential and a very high risk assessment rating.
The dam's primary purpose is flood risk reduction, with a controlled spillway and a maximum discharge capacity of 939,000 cubic feet per second. The reservoir created by the dam has a normal storage capacity of 505,381 acre-feet and a surface area of 22,420 acres. The USACE actively manages dam-related flood risks by conducting regular inspections, maintaining the structure, and engaging with local emergency managers to ensure preparedness and response in case of a dam-related emergency.
Despite the inherent risks associated with dams, the USACE remains vigilant in monitoring the condition and health of the Keystone Dam to mitigate potential hazards. Through ongoing risk management measures, including the development of emergency action plans and collaboration with local stakeholders, the USACE works to ensure the safety and integrity of the dam and surrounding communities.

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 Keystone Dam - Cleveland Levee
Where does the data for Keystone Dam - Cleveland 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.
