Summary
Built in 1957, this earth dam stands at a height of 27 feet and spans a length of 371 feet, with a storage capacity of 26 acre-feet. The dam is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and is subject to state permitting, inspection, and enforcement.
Managed by the Natural Resources Conservation Service, Stockton Number 1 has a low hazard potential and is currently rated as "Not Rated" in terms of its condition assessment. While the dam has not been fully assessed for emergency preparedness, it is reassuring to know that it meets state regulatory guidelines and is inspected periodically. The dam's primary purpose and associated structures are not specified in the data, but its location in a critical area along the river underscores its importance for water resource management and climate resilience efforts in the region.
With its strategic placement in the St. Paul District of the US Army Corps of Engineers and oversight by the state regulatory agency, Stockton Number 1 plays a crucial role in water storage and flood control along the TR-BAD River. As a point of interest for water resource and climate enthusiasts, this dam serves as a reminder of the intricate network of infrastructure that supports water management in South Dakota and the ongoing efforts to ensure its safety and effectiveness for the surrounding communities.

Dam Data Reference
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.
