King Dam No. 2 dam
King Dam No. 2
King Dam No. 2, located in Haakon, South Dakota, is a privately owned earth dam constructed in 1954 with a height of 18 feet and a length of 1160 feet. Situated on the TR-Bad River, the dam provides essential water resource management for the region, with a normal storage capacity of 133 acre-feet and a maximum storage of 218 acre-feet. Despite its crucial role in regulating water flow and storage, the dam is currently assessed as having a high hazard potential and poor condition.
Managed by the Natural Resources Conservation Service, King Dam No. 2 is subject to state regulations and inspections, ensuring its structural integrity and safety. The dam has a history of modifications, with the last inspection conducted in November 2020. With a hazard potential rating of high, stakeholders and authorities must remain vigilant in monitoring and maintaining the dam to reduce potential risks and ensure public safety in the event of emergencies.
For water resource and climate enthusiasts, King Dam No. 2 serves as a focal point for understanding the intersection of infrastructure, environmental stewardship, and climate resilience. As a vital component of the region's water management system, the dam's condition and regulatory oversight are crucial factors in safeguarding the surrounding community and ecosystems. Ongoing monitoring and risk assessment efforts are imperative to address the dam's current poor condition and mitigate potential hazards, underscoring the importance of proactive maintenance and emergency preparedness in the face of changing climate dynamics.

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 King Dam No. 2
Where does the data for King Dam No. 2 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 High 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.
