About this dam

James Petik No.2

James Petik No.2 is a private dam located in Corson, South Dakota, with a low hazard potential and a height of 16 feet. Built in 1950 and managed by the Natural Resources Conservation Service, this earth dam spans 326 feet in length and has a storage capacity of 64 acre-feet. Situated on the TR-GRAND river or stream, the dam plays a crucial role in regulating water flow and storage in the area.

Despite its age, James Petik No.2 is well maintained and meets state regulatory requirements for inspection, permitting, and enforcement. With a normal storage capacity of 51 acre-feet and a maximum discharge of 536 cubic feet per second, the dam serves as an important water resource for the region. As a key piece of infrastructure in the St. Paul District managed by the federal government, the dam contributes to flood control and water management efforts in South Dakota.

Overall, James Petik No.2 stands as a testament to the importance of sustainable water resource management in the face of changing climates. Its role in mitigating flood risks and ensuring water availability underscores the need for continued monitoring and maintenance to support the region's water security. As water resource and climate enthusiasts, understanding the significance of dams like James Petik No.2 is crucial in safeguarding our natural environment and adapting to the challenges of a changing climate.

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 James Petik No.2

Where does the data for James Petik No.2 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.
