Summary
Built in 1957, this earth dam is 22 feet high and spans 340 feet in length, with a storage capacity of 54 acre-feet. Despite not having a designated primary purpose, the dam serves as a vital resource for water storage and management in the region.
With a hazard potential rated as significant, the condition of Zeke Allart Dam has not been formally assessed since an inspection in 1980. Despite this, the dam remains under state regulatory oversight, with an established inspection, permitting, and enforcement system in place. The dam's emergency action plan (EAP) status and risk management measures are currently unaddressed, highlighting a potential area for improvement in ensuring the safety and resilience of the structure in the face of changing climate conditions.
As a key component of the water infrastructure in the area, Zeke Allart Dam plays a crucial role in flood control, irrigation, and water supply for the surrounding communities. With its historical significance and ongoing relevance in the region's water resource management, the dam serves as a focal point for water and climate enthusiasts interested in understanding the intersection of infrastructure, regulation, and environmental stewardship in South Dakota.

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.
