Summary
Built in 1940, this Earth type dam stands at a height of 13 feet and has a length of 1000 feet. With a storage capacity of 110 acre-feet, the dam serves a primary purpose that is not specified in the data. Despite being state-regulated and inspected by the South Dakota Department of Environment and Natural Resources, the dam's hazard potential is rated as low and its condition is currently not assessed.
Owned and operated by a private entity, Sd Noname 190 is not funded or regulated by any federal agencies. The dam's maximum discharge capacity is 900 cubic feet per second, with a normal storage capacity of 35 acre-feet. While the dam does not have a spillway or locks, its emergency action plan status and risk assessment details are unknown. With no reported modifications or recent inspections, the dam's overall risk management measures and readiness for emergencies remain unclear. Located in a rural area with limited development, Sd Noname 190 presents a low risk to surrounding communities and infrastructure.

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.
