Summary
The association manages a dam constructed in 1946 with a height of 25 feet and a length of 500 feet, providing a maximum storage capacity of 108 acre-feet and a normal storage level of 49 acre-feet. The dam serves the primary purpose of water resource management and is under state regulation, permitting, inspection, and enforcement by the South Dakota Department of Environment and Natural Resources (DENR).
The dam at Red Earth Grazing Association has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam does not fall under the jurisdiction of the US Army Corps of Engineers, it plays a crucial role in flood control and water storage for the surrounding area. The association has not updated emergency action plans or conducted risk assessments recently, highlighting the importance of ongoing maintenance and monitoring to ensure the safety and effectiveness of the dam in the face of changing climate conditions and water resource demands.
Despite its low hazard potential, the Red Earth Grazing Association dam remains a vital infrastructure for water management in the region. As climate change continues to impact water resources, it is essential for the association to prioritize regular inspections, maintenance, and emergency preparedness to safeguard the dam and the surrounding community from potential risks. Collaboration with state agencies and stakeholders will be crucial in ensuring the long-term resilience and sustainability of the dam in the face of evolving climate challenges.

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.
