Hald Ranch Pond dam
Hald Ranch Pond
Hald Ranch Pond, located in Fall River, South Dakota, is a privately-owned earth dam structure that serves multiple purposes including water storage and flood control. Built in 1955 with a height of 16 feet and a length of 460 feet, this reservoir has a storage capacity of 102 acre-feet of water. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, with a low hazard potential rating.
Situated on the TR-Cheyenne river system and managed by the Omaha District of the US Army Corps of Engineers, Hald Ranch Pond plays a crucial role in water resource management in the region. With a maximum discharge capacity of 1320 cubic feet per second, this reservoir helps mitigate the impacts of extreme weather events and supports the local ecosystem. Despite being privately owned, the dam is subject to state regulations and enforcement measures to ensure its structural integrity and safety for surrounding communities.
Although the condition assessment of Hald Ranch Pond is currently not rated, its importance in water supply and climate resilience cannot be understated. As water resource and climate enthusiasts, understanding the role of such structures in managing water resources and adapting to changing climate patterns is vital for sustainable development and ecosystem conservation 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 Hald Ranch Pond
Where does the data for Hald Ranch Pond 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.
