Summary
Built in 1949, this earth dam stands at 16 feet high with a length of 385 feet. It has a storage capacity of 128 acre-feet, with a normal storage level of 62 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), ensuring that it meets all state permitting, inspection, and enforcement requirements.
Despite its low hazard potential, Ankony Ranch INC has not been rated for its condition assessment. With a maximum discharge capacity of 1650 cubic feet per second, the dam serves as a vital structure for managing water resources in the area. While it does not have spillways or locks, it plays a crucial role in controlling water flow and preventing flooding. The dam has not undergone any significant modifications in recent years, indicating its stability and effectiveness in water management.
Ankony Ranch INC is a key component of the water infrastructure in Hyde County, South Dakota, and ensures the safety and security of nearby residents and properties. While it may not be highly visible or well-known, its role in regulating water flow and mitigating potential risks is vital for the local community. As climate change continues to impact water resources, structures like Ankony Ranch INC play a crucial role in adapting to and mitigating these challenges.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
