Randall Rc&D #31a dam
Randall Rc&D #31a
Randall Rc&D #31a is a local government-owned earth dam located in Bon Homme, South Dakota. Built in 1968 by the USDA NRCS, this dam stands at a height of 31 feet and stretches 415 feet in length, providing a storage capacity of 54 acre-feet. Situated in the TRIB. MISSONot RatedI RIVER, this structure is regulated by the state and inspected regularly to ensure its safety and functionality. Despite its low hazard potential, the dam's condition assessment is currently not rated.
Managed by the Natural Resources Conservation Service, Randall Rc&D #31a plays a crucial role in water resource management and climate resilience in the region. With a maximum discharge capacity of 746 cubic feet per second, this dam helps to control flooding and manage water flow in the area. Its primary purpose and associated structures are not specified, but its presence is vital for maintaining water security and environmental sustainability in South Dakota.
While the specifics of emergency preparedness and risk management measures for Randall Rc&D #31a are not detailed in the available data, its significance as a water resource infrastructure underscores the importance of ongoing monitoring and maintenance. As climate change continues to impact water availability and quality, structures like this earth dam play a critical role in ensuring the resilience of communities and ecosystems in the face of changing conditions.

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 Randall Rc&D #31a
Where does the data for Randall Rc&D #31a 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.
