Summary
Built in 1950 by the Natural Resources Conservation Service, this dam stands at 24 feet high with a length of 500 feet, providing a storage capacity of 112 acre-feet. Despite being rated as low hazard potential and not currently assessed for condition, this dam is regulated by the state regulatory agency DENR, with permitting, inspection, and enforcement all in place to ensure its safety and functionality.
The dam's purpose and associated structures are not specified, but it serves as a vital water resource for the surrounding area with a normal storage capacity of 45 acre-feet. With a maximum discharge capacity of 1500 cubic feet per second, Ray Haberman Sr No.1 plays a crucial role in managing water flow and storage in the region. While no recent inspection or assessment data is available, the dam's low hazard potential indicates a relatively low risk of failure or adverse impacts on downstream communities.
As a significant part of the water infrastructure in South Dakota, Ray Haberman Sr No.1 contributes to the overall water management and climate resilience efforts in the region. With its strategic location along the TR MOREAU river and state regulatory oversight, this dam serves as a key component in safeguarding water resources and mitigating potential risks associated with extreme weather events. Its construction and maintenance reflect a commitment to sustainable water resource management and the protection of local communities from flooding and water-related hazards.

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.
