Summary
Built in 1950, this earth dam stands at a height of 19 feet with a length of 200 feet, providing a storage capacity of 100 acre-feet. Despite its modest size, the dam plays a crucial role in regulating water flow and storage in the area, with a maximum discharge capacity of 567 cubic feet per second.
Managed by the South Dakota Department of Environment and Natural Resources (DENR), Sd Noname 253 is subject to state regulations, inspections, and enforcement measures to ensure its safety and functionality. Classified as a low hazard potential structure, the dam has not been rated for its condition assessment, but it continues to serve its primary purpose of water management effectively. With no associated structures and a lack of detailed information on emergency action plans and risk assessments, there is room for further evaluation and improvement to enhance the dam's resilience to potential climate impacts.
As water resources and climate enthusiasts continue to monitor and assess the role of dams in mitigating the effects of climate change, Sd Noname 253 stands as a testament to the importance of small-scale infrastructure in water management. With its state-regulated status and low hazard potential, this earth dam represents a critical piece of South Dakota's water infrastructure, contributing to the overall resilience of the region's water systems. Further attention and investment in monitoring and maintenance will be key to ensuring the continued functionality and safety of Sd Noname 253 in the face of evolving climate challenges.

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.
