Stanley Dam dam
Stanley Dam
Stanley Dam, located on the Little Knife River in Mountrail, North Dakota, is a vital water resource infrastructure managed by the North Dakota State Water Commission. Completed in 1968, this earth dam stands at a height of 20.5 feet and has a storage capacity of 3,720 acre-feet, primarily used for water supply purposes. With a surface area of 253 acres and a normal storage capacity of 1,550 acre-feet, the dam plays a crucial role in managing water resources in the region.
Despite being classified as having a significant hazard potential, Stanley Dam has not been rated for its condition assessment. The dam features an uncontrolled spillway with a width of 100 feet and has not been modified in recent years. The risk assessment for the dam is moderate, and it is under the jurisdiction of the North Dakota State Water Commission for regulation, permitting, inspection, and enforcement. With a focus on water supply and serving as a local government-owned structure, Stanley Dam serves as a key component in the water infrastructure of the area, ensuring the sustainable management of water resources in the region.
As a significant water supply structure in North Dakota, Stanley Dam provides essential water storage and management capabilities for the surrounding area. With its stone core and soil foundation, the dam has been serving its purpose effectively since its completion in 1968. Despite its hazard potential, the dam has not been rated for its condition assessment, indicating the need for continued monitoring and maintenance to ensure its long-term reliability. The risk assessment for the dam is moderate, and with the North Dakota State Water Commission overseeing its regulation and operations, Stanley Dam remains a crucial asset for water resource and climate enthusiasts 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 Stanley Dam
Where does the data for Stanley 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 Significant 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.
