Summary
Built in 1957, this earth-type dam stands at a height of 17 feet and spans 545 feet in length, providing a storage capacity of 105 acre-feet. Situated on the TR-Bad River, this structure plays a crucial role in flood control and water resource management in the region.
Despite its low hazard potential, Sd Noname 116 has not been rated for its condition assessment, indicating a need for further evaluation and maintenance. The dam's emergency action plan readiness, risk assessment, and management measures are also currently unspecified, highlighting areas for improvement in ensuring the safety and resilience of the structure. With its state-regulated status and importance in the local water infrastructure, ongoing monitoring and proactive measures will be key in safeguarding the surrounding community and environment.
Managed by the Natural Resources Conservation Service, Sd Noname 116 serves as a vital component of the St. Paul District's water management system. Its strategic location and design contribute to the overall water resource management efforts in the region, making it a significant asset for climate and water enthusiasts interested in understanding the dynamics of dam infrastructure and its impact on local ecosystems.

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.
