Summary
Ingalls No.2 is a private earth dam located in Meade, South Dakota, along the TR CHEYENNE river. Completed in 1949, this dam stands at a height of 21 feet and has a storage capacity of 84 acre-feet, with a normal storage level of 37 acre-feet. Despite its low hazard potential, the dam has not been rated for its condition assessment, and no recent inspection date is available.
Owned and regulated by private entities, this dam falls under the jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR) for permitting, inspection, and enforcement. Although there are no associated structures or federal agency involvement, the Natural Resources Conservation Service was responsible for its design. With a maximum discharge capacity of 1200 cubic feet per second, L. Ingalls No.2 plays a crucial role in water resource management in the region.
For water resource and climate enthusiasts, L. Ingalls No.2 presents an interesting case study in dam infrastructure in South Dakota. With its historical significance and continued role in water storage and management along the TR CHEYENNE river, this earth dam serves as a reminder of the importance of proper regulation and maintenance to ensure the safety and sustainability of water resources in the area. While its condition assessment remains unknown, the dam's low hazard potential suggests a relatively stable and secure structure, albeit one that may benefit from further evaluation and monitoring in the future.

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.
