Summary
Completed in 1935, it stands at a height of 22 feet and has a length of 370 feet, providing a storage capacity of 1100 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources (DENR), Pius Aberle is regulated, permitted, inspected, and enforced by state agencies to ensure compliance with safety standards.
Despite being classified as a low hazard potential dam, Pius Aberle's condition assessment is currently marked as "Not Rated," indicating a need for further evaluation. The dam has not been rated for risk assessment, and emergency action plans, including inundation maps, are not readily available. Although the dam is not owned or funded by federal agencies, it plays a crucial role in water resource management in the region, with a maximum discharge of 1200 cubic feet per second.
Water resource and climate enthusiasts will find Pius Aberle an intriguing site for further exploration, given its historical significance, regulatory oversight, and potential risk assessment needs. As a private dam in a rural area, it serves as a reminder of the importance of maintaining and monitoring infrastructure for water supply, flood control, and environmental protection. Understanding the complexities of managing dams like Pius Aberle can provide valuable insights into the intersection of water resources, climate resilience, and infrastructure development.

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.
