Anderson 5 dam
Anderson 5
Anderson 5 is a privately owned earth dam located in Meade County, South Dakota. Built in 1945, it stands at a height of 16 feet and has a storage capacity of 64 acre-feet, with a normal storage level of 38 acre-feet. The dam spans 905 feet in length and is designed to handle a maximum discharge of 2350 cubic feet per second. Despite its age, Anderson 5 has been assessed as having a low hazard potential and its condition remains unrated.
Managed by the South Dakota Department of Environment and Natural Resources, Anderson 5 is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and compliance with regulations. While the dam does not have a designated primary purpose or associated structures, its role in water resource management and flood control in the TR-BELLE FONot RatedCHE river or stream watershed is significant. The dam's location within the Omaha District and under the oversight of the DENR reflects its importance in supporting water resource and climate initiatives in the region.
With no documented emergency action plan or risk assessment in place, Anderson 5 presents an opportunity for further evaluation and potential enhancements to its safety protocols. As a key infrastructure asset in the region, the dam's maintenance and monitoring are crucial for safeguarding the surrounding community and environment from potential hazards. By staying informed and engaged with the management of Anderson 5, water resource and climate enthusiasts can contribute to the sustainable stewardship of this essential piece of infrastructure in South Dakota.

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 Anderson 5
Where does the data for Anderson 5 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.
