Krapp Dam; John dam
Krapp Dam; John
Krapp Dam, also known as John Dam, is a privately owned structure located in Stutsman, North Dakota. Built in 1989 by the Soil Conservation Service (SCS), this earth dam serves as a Fish and Wildlife Pond along the Seven Mile Coulee river or stream. With a height of 10 feet and a storage capacity of 139.7 acre-feet, Krapp Dam plays a crucial role in supporting the local ecosystem by providing habitat for various aquatic species.
Managed by the North Dakota State Water Commission (NDSWC) and regulated by the state, Krapp Dam has a low hazard potential and a moderate risk assessment rating. Equipped with a vertical lift outlet gate, the dam has not been formally assessed for its condition but is considered to be in a satisfactory state. While the dam does not have a formal Emergency Action Plan (EAP) in place, its risk management measures ensure the safety of surrounding areas in case of any unforeseen events.
Despite its modest size, Krapp Dam remains an important resource for water and climate enthusiasts in North Dakota. Its role in maintaining a healthy ecosystem and providing recreational opportunities underscores the significance of small-scale dams in supporting biodiversity and water conservation efforts in the region.

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 Krapp Dam; John
Where does the data for Krapp Dam; John 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.
