Summary
Renner is a privately owned earth dam located in Pollock, South Dakota, with a height of 26 feet and a length of 280 feet. Completed in 1952, the dam has a storage capacity of 50 acre-feet and a maximum discharge of 1200 cubic feet per second. Despite being rated as having a low hazard potential, the dam's condition assessment is currently listed as "Not Rated", indicating a need for further evaluation.
Managed by the Natural Resources Conservation Service, G. Renner is regulated by the South Dakota Department of Environment and Natural Resources, with state permitting, inspection, and enforcement in place. The dam falls under state jurisdiction and is subject to state regulatory agencies. While its Emergency Action Plan (EAP) status and risk assessment details are not provided in the data, the dam's location on the TR-MISSO river system highlights its importance in managing water resources and climate considerations in the area.
With its strategic placement in Campbell County, South Dakota, G. Renner plays a crucial role in water resource management and flood control efforts in the region. As water resource and climate enthusiasts, understanding the structural and regulatory aspects of dams like G. Renner is essential for ensuring the safety and sustainability of water infrastructure in the face of changing environmental conditions.

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.
