Royal Mcknight Dam No.1 dam
Royal Mcknight Dam No.1
Royal Mcknight Dam No.1, located in Butte, South Dakota, is a privately owned earth dam constructed in 1967 by the Natural Resources Conservation Service. With a height of 17 feet and a length of 1390 feet, this dam plays a crucial role in managing the flow of the Harriet-Draw river. It has a maximum storage capacity of 243 acre-feet and a normal storage of 78 acre-feet, helping to regulate water levels and mitigate floods in the area.
Despite being classified as having a low hazard potential, Royal Mcknight Dam No.1 is regulated by the South Dakota Department of Environment and Natural Resources. It undergoes regular inspections, permitting, and enforcement to ensure its structural integrity and compliance with safety standards. With State jurisdiction and oversight, this dam serves as a vital infrastructure for water resource management and climate resilience in the region, contributing to the overall environmental sustainability and water security of Butte, South Dakota.
For water resource and climate enthusiasts, Royal Mcknight Dam No.1 represents a significant piece of infrastructure that not only provides water storage but also contributes to flood control and environmental protection in the area. Its presence highlights the importance of proper management and regulation of dams to ensure their safe and effective operation for the benefit of the community and the surrounding ecosystem. As a key component of water resource management in South Dakota, this dam plays a crucial role in safeguarding both water availability and environmental sustainability for future generations.

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 Royal Mcknight Dam No.1
Where does the data for Royal Mcknight Dam No.1 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.
