Laintz Dam; Dan dam
Laintz Dam; Dan
Laintz Dam, also known as Dan, is a privately owned earth dam located in Sioux County, North Dakota. Built in 1976 by USDA NRCS, this dam serves multiple purposes including fire protection, stock containment, and as a small fish pond. The dam has a height of 17 feet and a length of 700 feet, with a storage capacity of 87 acre-feet and a surface area of 10 acres. It is regulated by the North Dakota State Water Commission and is inspected regularly to ensure its structural integrity.
The dam is situated on Porcupine Creek, tributary to the Missouri River, within the jurisdiction of the NDSWC. With a spillway width of 45 feet and uncontrolled spillway type, the dam has a low hazard potential and a moderate risk assessment rating. While the condition assessment is currently not rated, the dam's risk management measures are in place to mitigate any potential risks. The dam does not have outlet gates and is not associated with any locks, making it a relatively simple structure with a primary focus on water storage for various uses.
Overall, Laintz Dam; Dan represents a vital water resource in the region, providing essential services for fire protection, stock containment, and recreational activities. As a privately owned structure, it is subject to state regulations and inspections to ensure public safety and environmental compliance. With its modest size and low hazard potential, the dam plays a crucial role in water management and conservation efforts in North Dakota.

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 Laintz Dam; Dan
Where does the data for Laintz Dam; Dan 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.
