Summary
Completed in 1962, this earth dam stands at 23 feet tall and has a storage capacity of 64 acre-feet. The dam is situated on the TR-Cheyenne River and falls under the jurisdiction of the South Dakota Department of Environment and Natural Resources (DENR).
Despite being categorized as having low hazard potential, Sd Noname 252 has not been rated for its condition assessment. The dam has not undergone recent inspections, and there is no information available regarding emergency action plans, risk assessments, or risk management measures. The dam's last known update was on June 1, 2021, and it is not owned or funded by any federal agency.
Water resource and climate enthusiasts interested in the maintenance and regulation of dams may find Sd Noname 252 intriguing due to its private ownership and state-regulated status. The dam's location on the Cheyenne River, its relatively small storage capacity, and the lack of detailed information on its condition and emergency preparedness could spark further curiosity and research into the monitoring and management of this particular water infrastructure.

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.
