Summary
This earth dam stands at a height of 30 feet and stretches for 750 feet, with a storage capacity of 180 acre-feet. Completed in 1957, it serves the primary purpose of water resource management in the region, with a maximum discharge capacity of 405 cubic feet per second.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 112 is regulated, permitted, inspected, and enforced by the state agency to ensure its safety and functionality. The dam has been classified with a significant hazard potential, although its condition assessment is currently listed as 'Not Rated'. Emergency action plans and risk assessments for the dam are yet to be fully developed, indicating a potential area for improvement in terms of preparedness for any unforeseen events.
Situated in a picturesque location near the city of Philip, this dam plays a crucial role in water supply and flood control along the TR-BAD RIVER. With its historical significance dating back to the 1950s, Sd Noname 112 stands as a testament to the engineering feats undertaken in South Dakota's water resource management efforts.

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.
