Summary
Built in 1950 by the Natural Resources Conservation Service, this earth dam stands at a height of 14 feet and has a length of 660 feet. With a storage capacity of 95 acre-feet and a normal storage of 56 acre-feet, the dam serves a low hazard potential with a condition assessment of "Not Rated".
Despite being state regulated and permitted, Sd Noname 149 has not been inspected recently and lacks emergency action preparedness measures. The dam's primary purpose and associated structures are unspecified, leaving its risk assessment and management measures unknown. Its location in a rural area under the St. Paul District of the US Army Corps of Engineers adds to the complexity of its oversight and maintenance.
Water resource and climate enthusiasts may find Sd Noname 149 intriguing for its historical significance and potential environmental impact. With limited data available on its current condition and management practices, there is a need for further investigation and monitoring to ensure the safety and sustainability of this dam in the face of changing climate patterns and water resource demands.

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.
