Heiser Pond dam
Heiser Pond
Heiser Pond, located in Fall River, South Dakota, is a privately owned water resource regulated by the state's Department of Environment and Natural Resources. This Earth-type dam was completed in 1949 and stands at a height of 14 feet, with a storage capacity of 56 acre-feet and a maximum discharge of 585 cubic feet per second. Despite its low hazard potential and current "Not Rated" condition assessment, the pond plays a crucial role in the local ecosystem as a tributary of the White River.
Managed by the Natural Resources Conservation Service, Heiser Pond serves as a vital water source for the surrounding area and supports diverse wildlife and vegetation. The pond's normal storage capacity of 44 acre-feet helps maintain stable water levels and supports a healthy aquatic ecosystem. While the pond's emergency action plan and risk assessment details are currently unavailable, its strategic location and historical significance make it a key focal point for water resource and climate enthusiasts interested in the sustainable management of freshwater resources in the region.
As climate change continues to impact water availability and quality, Heiser Pond stands as a testament to the importance of responsible water management practices. With its controlled release mechanisms and state-mandated inspections, the pond exemplifies the collaboration between private ownership and government oversight to ensure the safety and sustainability of water resources in South Dakota. For those passionate about water conservation and climate resilience, Heiser Pond represents a unique opportunity to study the intersection of human infrastructure and natural ecosystems in the face of a changing climate.

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 Heiser Pond
Where does the data for Heiser 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.
