About this dam

Oahe Dam - Spring Creek Dam

Oahe Dam, also known as Spring Creek Dam or Lake Pocasse, is a federal-owned earth dam located in South Dakota. Completed in 1961, this dam on Spring Creek serves multiple purposes, with a primary function of providing flood control and water storage. The dam stands at a height of 40 feet and has a length of 3200 feet, with a storage capacity of 26,000 acre-feet.

Managed by the US Army Corps of Engineers, Oahe Dam has a low hazard potential and is regularly inspected to ensure its structural integrity. The dam's risk management measures include ongoing monitoring, maintenance activities, and collaboration with local emergency managers to prepare for potential dam-related emergencies. Despite the dam's capacity to store water and manage flood risk, severe weather events can still pose challenges, which may result in controlled releases or other measures to maintain dam safety.

Overall, Oahe Dam plays a crucial role in water resource management and climate resilience efforts in the region. As part of the US Army Corps of Engineers' portfolio, the dam is closely monitored and managed to address flood risks and ensure the safety of surrounding communities. Continued updates and maintenance activities are essential to support the dam's functionality and readiness to respond to 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.

FAQ

About Oahe Dam - Spring Creek Dam

Where does the data for Oahe Dam - Spring Creek Dam 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 Low 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.
