Goodnick Dam dam
Goodnick Dam
Goodnick Dam, located in Fall River, South Dakota, is a privately owned structure that plays a crucial role in water resource management in the region. Completed in 1951, this Earth-type dam stands at a height of 13 feet and has a storage capacity of 130 acre-feet, with a maximum discharge of 975 cubic feet per second. Situated on a tributary of the White River, the dam serves to regulate water flow, providing essential irrigation and flood control benefits to the surrounding areas.
Despite its low hazard potential and the lack of a formal condition assessment, Goodnick Dam is subject to state regulation, inspection, and enforcement by the South Dakota Department of Environment and Natural Resources (DENR). While the dam has not been rated for its current condition, it is periodically inspected to ensure its structural integrity and operational effectiveness. With its primary purpose and specific uses undisclosed in the available data, the dam remains a significant infrastructure for water management in the region.
With a notable presence in the local landscape, Goodnick Dam stands as a testament to the importance of water resource management and climate resilience in South Dakota. While further details on its associated structures, emergency preparedness measures, and risk management strategies are not provided, the dam's role in maintaining water supply and mitigating potential flood risks underscores its importance in safeguarding the region's water resources and supporting sustainable development for the future.

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 Goodnick Dam
Where does the data for Goodnick Dam 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.
