Leo Ruona Pond No.1 dam
Leo Ruona Pond No.1
Leo Ruona Pond No.1, located in Harding, South Dakota, is a privately owned earth dam constructed in 1959 with a maximum storage capacity of 60 acre-feet. The dam stands at a height of 16 feet and spans a length of 330 feet, serving as a vital structure along the TR-SAND CREEK. Managed by the South Dakota Department of Environment and Natural Resources (DENR), this dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations.
Despite being classified as having a low hazard potential and being in "Not Rated" condition, Leo Ruona Pond No.1 plays a crucial role in water resource management and climate resilience in the region. With a normal storage capacity of 36 acre-feet and a maximum discharge capability of 630 cubic feet per second, this dam serves as a vital component in flood control and water supply for the area. Furthermore, the dam's location within the Omaha District underlines its significance in the broader water infrastructure network of the region.
While specific hazard potential and condition ratings are not available for Leo Ruona Pond No.1, its presence as a regulated and regularly inspected structure underscores its importance in maintaining water security and mitigating climate-related risks. As a private earth dam with state jurisdiction, this facility represents a collaborative effort between the owner and regulatory agencies to ensure the safety and functionality of the dam for the benefit of the surrounding communities and ecosystem. The data on Leo Ruona Pond No.1 highlights its role in sustainable water management and underscores the interconnected nature of water resources and climate resilience 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 Leo Ruona Pond No.1
Where does the data for Leo Ruona Pond 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.
