Summary
This dam, completed in 1954, stands at 25 feet in height and spans 150 feet in length, providing a storage capacity of 250 acre-feet. Managed by the Natural Resources Conservation Service, this dam is regulated by the South Dakota Department of Environment and Natural Resources and undergoes regular inspections, enforcement, and permitting to ensure its safety and compliance with state regulations.
With a low hazard potential and a condition assessment of "Not Rated," Sd Noname 236 serves as a vital infrastructure for water resource management in the region. While the dam has not been modified in recent years, it is equipped with a maximum discharge capacity of 300 cubic feet per second and a normal storage capacity of 112 acre-feet. Despite its unassuming name and remote location, this dam plays a crucial role in controlling water flow and protecting downstream areas from potential flooding events.
The surrounding community benefits from the presence of Sd Noname 236, as it helps mitigate flood risks, provides water storage for agricultural and municipal purposes, and contributes to overall water resource management in the region. As climate change continues to impact water availability and extreme weather events, the importance of well-maintained dams like Sd Noname 236 becomes increasingly evident in ensuring the resilience and sustainability of water resources for future generations.

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.
