Summary
Built in 1940 by the Natural Resources Conservation Service, this earth dam stands at a height of 25 feet and spans 540 feet in length. With a storage capacity of 190 acre-feet, the dam serves multiple purposes, including flood control and irrigation for the surrounding area.
Despite being classified as having a low hazard potential, Sd Noname 288 is regulated and inspected by the South Dakota Department of Environment and Natural Resources. The dam has a maximum discharge capacity of 840 cubic feet per second, ensuring effective water management during heavy rainfall events. While the condition assessment is currently listed as "Not Rated," the dam's emergency action plan status and risk assessment are not available at this time.
Managed by private owners, Sd Noname 288 plays a crucial role in water resource management in the region. With its strategic location and capacity, this dam contributes to the overall resilience of the local water infrastructure, highlighting the importance of sustainable dam operations and maintenance practices in the face of changing climate patterns.

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.
