Summary
Constructed in 1958 by the Natural Resources Conservation Service, this Earth-type dam stands at a height of 17 feet and has a length of 470 feet. With a storage capacity of 204 acre-feet, it serves the primary purpose of reservoir storage, providing essential water resources for the surrounding area.
Despite being categorized as having a low hazard potential and not yet rated for its condition assessment, Sd Noname 23 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources (DENR). With a maximum discharge capacity of 4200 cubic feet per second, this dam plays a crucial role in managing water flow and mitigating potential flood risks in the region. While it currently does not have an Emergency Action Plan (EAP) in place, the dam's risk assessment and management measures are yet to be determined.
With its strategic location and functional design, Sd Noname 23 serves as a vital infrastructure for water resource management in South Dakota. As enthusiasts of water resources and climate, understanding the significance and operational aspects of dams like Sd Noname 23 is essential for promoting sustainable water management practices and ensuring the resilience of water systems in the face of changing climate conditions.

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.
