Summary
#1 is a privately owned dam located in Jones, South Dakota, along the TR-BAD River. Constructed in 1957 by the Natural Resources Conservation Service, this earth dam stands at a height of 27 feet and spans a length of 542 feet. With a storage capacity of 24 acre-feet, the dam serves the primary purpose of regulating and storing water for agricultural purposes.
Managed by the South Dakota Department of Environment and Natural Resources, Olson Ranches INC. #1 is subject to state regulation, inspection, and enforcement. Despite its low hazard potential and a lack of current condition assessment, the dam remains in operation with a normal storage capacity of 16 acre-feet. While the dam does not have an Emergency Action Plan in place, it meets state permitting requirements and serves as a vital resource for water management in the region.
The dam's location within the St. Paul District and its oversight by Congressman Dusty Johnson highlight its significance in the local water resource infrastructure. With a maximum discharge capacity of 861 cubic feet per second, Olson Ranches INC. #1 plays a crucial role in water conservation and agricultural sustainability in the area.

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.
