Summary
Constructed in 1952 by the Natural Resources Conservation Service, this dam stands at a height of 16 feet and has a storage capacity of 147 acre-feet. Despite its low hazard potential, Sd Noname 216 is regulated by the South Dakota Department of Environment and Natural Resources, with state jurisdiction, permitting, inspection, and enforcement all in place to ensure its safety and compliance with regulations.
The dam serves multiple purposes, although the primary purpose is not specified in the data. With a normal storage capacity of 48 acre-feet and a maximum discharge of 1122 cubic feet per second, Sd Noname 216 plays a crucial role in water resource management in the region. While the dam's condition assessment is listed as "Not Rated," its hazard potential is low, suggesting a relatively low risk of failure or adverse impacts on the surrounding environment and communities.
The precise design and function of Sd Noname 216 remain somewhat mysterious, with limited details on its structure, spillway, outlet gates, and associated structures. However, its presence on the TR Bad River and its ownership by a private entity underscore the complex interplay between water resource management, climate resilience, and private land ownership in South Dakota. As water resource and climate enthusiasts, further investigation and monitoring of Sd Noname 216 could provide valuable insights into the intersection of human infrastructure and natural ecosystems in this dynamic region.

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.
