Summary
Completed in 1959, this earth dam stands at a height of 25 feet and has a storage capacity of 41 acre-feet. With a maximum discharge of 1890 cubic feet per second, the dam poses a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment.
Despite being a privately owned structure, Livermore #1 is regulated by the South Dakota Department of Environment and Natural Resources (DENR), with state jurisdiction, permitting, inspection, and enforcement all in place. The dam has not undergone any modifications in recent years, and important emergency preparedness measures such as an Emergency Action Plan (EAP) are currently not prepared or updated. The dam does not fall under the jurisdiction of the US Army Corps of Engineers.
For water resource and climate enthusiasts, Livermore #1 presents an intriguing case study of a privately owned dam in a rural area with potential implications for water storage, flood control, and environmental impact. The presence of state regulatory oversight ensures a level of safety and compliance, while the dam's modest size and low hazard potential offer insight into the diverse landscape of water infrastructure across the United States. Further research and monitoring of Livermore #1 could provide valuable data for understanding the intersection of private ownership, state regulation, and community resilience in the face of changing climate conditions.

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.
