Summary
Barrick Estate in South Dakota is a privately owned dam located on the tributary of Minneconjou Creek. Built in 1958, this earth dam stands at 28 feet high and spans 300 feet in length, with a storage capacity of 29 acre-feet. While the dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR), it has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment.
Managed by the Natural Resources Conservation Service, the W.N. Barrick Estate dam plays a crucial role in water resource management in the region. With a maximum discharge capacity of 500 cubic feet per second, the dam serves as a vital infrastructure for flood control and water storage. Despite its importance, the dam has not been assessed for emergency action preparedness or updated on emergency contacts, indicating a need for further evaluation and planning in case of unforeseen events.
For water resource and climate enthusiasts, the W.N. Barrick Estate serves as a fascinating case study of a privately owned dam with state regulatory oversight. While the dam's low hazard potential suggests a lower risk of failure, the lack of recent inspections and emergency preparedness raises concerns about its resilience in the face of changing environmental conditions. As efforts continue to address the challenges of water resource management and climate adaptation, the W.N. Barrick Estate stands as a reminder of the importance of proactive monitoring and maintenance of critical infrastructure.

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.
