Peters Dam dam
Peters Dam
Peters Dam, located in Marshall, South Dakota, along the TR James River, was completed in 1997 by Konechne Eng. With a height of 23 feet and a length of 275 feet, the earth dam has a storage capacity of 64 acre-feet and a maximum discharge of 1080 cubic feet per second. Despite being privately owned, Peters Dam is regulated and inspected by the South Dakota Department of Environment and Natural Resources (DENR), ensuring its compliance with state standards for safety and environmental impact.
While Peters Dam is classified as having a low hazard potential, it is rated as having a moderate risk level. The dam features an uncontrolled spillway with a width of 80 feet and is surrounded by a drainage area of 2 square miles. The dam's condition is currently listed as "Not Rated," indicating the need for further assessment to determine its structural integrity and potential risks. Emergency action plans and other risk management measures are not specified for Peters Dam, suggesting a potential area for improvement in ensuring the safety and security of the surrounding community in the event of a dam failure.
Overall, Peters Dam serves as a vital structure for water resource management in the region, providing storage for irrigation, flood control, and water supply. It stands as a testament to engineering ingenuity and the importance of proper regulation and inspection to mitigate potential risks associated with dam infrastructure. As climate change continues to impact water resources and infrastructure, the maintenance and monitoring of dams like Peters Dam will be essential in ensuring the resilience of communities and ecosystems in the face of evolving climate challenges.

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 Peters Dam
Where does the data for Peters 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.
