Pensacola - Wyandotte Levee dam
Pensacola - Wyandotte Levee
The Pensacola-Wyandotte Levee, located in Ottawa County, Oklahoma, along the Grand River, is a vital structure designed for flood risk reduction. Built in 1941 by the US Army Corps of Engineers, this gravity dam stands at a height of 11 feet and stretches over 1300 feet, with a core made of stone. Despite its age, the Pensacola-Wyandotte Levee remains a critical barrier against potential flooding in the region.
With a high hazard potential and a risk assessment rating of 2 (high), emergency action plans have been prepared and updated regularly, meeting guidelines and ensuring the safety of surrounding communities. The levee has undergone inspections every 5 years, with the last assessment conducted in October 2014. Although the condition assessment is currently not available, the structure's integrity is maintained to protect against potential risks and ensure its effectiveness in flood control.
As part of the National Levee Database, the Pensacola-Wyandotte Levee system plays a crucial role in managing water resources and climate impacts in the area. With its history of construction and maintenance by the US Army Corps of Engineers, this levee serves as a testament to the ongoing efforts to mitigate flood risks and protect the local community from potential disasters.
Dam data reference
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 Pensacola - Wyandotte Levee
Where does the data for Pensacola - Wyandotte 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.
