Summary
Ogrady is a privately owned earth dam located in Meade, South Dakota, along the TR CHEYENNE river. Built in 1970, this dam stands at a height of 24 feet and has a storage capacity of 72 acre-feet. Despite being classified as low hazard potential, the dam has not been rated for its current condition. The Natural Resources Conservation Service is responsible for its design.
This dam plays a crucial role in water resource management in the area, with a maximum discharge capacity of 1200 cubic feet per second. It is regulated by the South Dakota Department of Environment and Natural Resources, which oversees permitting, inspection, and enforcement activities. The dam has not undergone any modifications or inspections recently, and its Emergency Action Plan status is unknown.
Overall, M. Ogrady serves as an important infrastructure for water conservation and flood control in the region. Its location along the TR CHEYENNE river and the involvement of state regulatory agencies ensure that it meets necessary safety standards. However, the lack of recent assessments and emergency preparedness information highlights the need for continued monitoring and maintenance to ensure the safety and effectiveness of this vital water resource structure.

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.
