Summary
Built in 1940, this Earth-type dam stands at a height of 18 feet and spans a length of 800 feet. It serves the purpose of regulating the flow of Settin Up Creek, with a maximum discharge capacity of 2500 cubic feet per second.
Despite being classified as a low hazard potential structure, Sd Noname 187 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources (DENR). With a storage capacity of 125 acre-feet, the dam plays a crucial role in managing water resources in the area. Although its condition assessment is currently marked as "Not Rated," the dam meets all regulatory guidelines for safety and emergency preparedness.
While the dam has not been modified in recent years and lacks certain detailed information such as inspection dates and emergency action plan status, its presence underscores the importance of maintaining and monitoring infrastructure for water resource management and climate resilience efforts in the region. As water resource and climate enthusiasts, staying informed about the state of dams like Sd Noname 187 is key to ensuring the sustainable utilization 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.
