Summary
Constructed in 1955 by the Natural Resources Conservation Service, this dam stands at a height of 22 feet and has a storage capacity of 135 acre-feet. With a maximum discharge rate of 2100 cubic feet per second, Sd Noname 254 serves as a crucial water resource infrastructure in the region.
Despite being classified as having a low hazard potential and not yet rated for its condition assessment, Sd Noname 254 is regulated, permitted, inspected, and enforced by the South Dakota Department of Environment and Natural Resources. While the dam has not undergone recent modifications or inspections, it is important to note that emergency action plans and risk assessments are not currently in place. With Dusty Johnson (R) as the congressional representative for the area, the dam plays a significant role in water management within the St. Paul District.
Water resource and climate enthusiasts will find Sd Noname 254 to be a fascinating case study in dam infrastructure management. With its historical significance, moderate storage capacity, and critical location along the TR-CHEYENNE RIVER, this privately owned dam provides valuable insights into the complexities of water resource regulation and maintenance. As discussions around climate change and water scarcity continue to evolve, Sd Noname 254 stands as a tangible example of the intersection between human infrastructure and environmental stewardship.

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.
