Summary
Built in 1965, this earth-type dam stands at a height of 17 feet and has a storage capacity of 82 acre-feet. The dam, with a length of 430 feet, is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, enforcement, and permitting processes.
Despite being classified as having a low hazard potential and being in "Not Rated" condition, Sd Noname 65 plays a crucial role in water resource management in the region. With a maximum discharge capacity of 1470 cubic feet per second, the dam serves as a vital infrastructure for flood control and water supply purposes. Managed by the Natural Resources Conservation Service, the dam's primary purpose and associated structures are not explicitly mentioned, but its significance in the local hydrological system is apparent.
The dam's location, design, and operational history make Sd Noname 65 an intriguing subject for water resource and climate enthusiasts. As an essential component of the St. Paul District's water management infrastructure, this dam embodies the intersection of human engineering with natural forces, highlighting the ongoing challenges and opportunities in sustainable water resource management in South Dakota.

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.
