Summary
Built in 1954, this earth dam stands at a height of 20 feet and has a length of 700 feet. With a storage capacity of 132 acre-feet, it serves the purpose of flood control and water management in the region. Managed by the Natural Resources Conservation Service, Abigale is regulated by the South Dakota Department of Environment and Natural Resources, ensuring regular inspections and enforcement of safety measures.
Despite its low hazard potential, Abigale has not been rated for its current condition. It has a maximum discharge capacity of 1260 cubic feet per second and a normal storage capacity of 85 acre-feet. While the dam has not been modified in recent years, its emergency action plan status and risk assessment measures remain unspecified. With its location in a remote area and limited associated structures, Abigale presents an intriguing case study for water resource and climate enthusiasts interested in the management and regulation of private dams in South Dakota.
Enthusiasts interested in Abigale can explore its historical significance as a key component of the region's water infrastructure. The dam's association with the Omaha District of the US Army Corps of Engineers and its role in the local ecosystem make it a valuable asset to study. As climate change continues to impact water resources, Abigale's management and maintenance serve as a critical example of how private dams contribute to the overall resilience of water systems in the face of environmental challenges.

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.
