Summary
Completed in 1959, this dam has a storage capacity of 58 acre-feet and a maximum discharge of 1575 cubic feet per second. It is regulated by the South Dakota Department of Environment and Natural Resources (DENR) and undergoes regular inspections, with a low hazard potential and a current condition assessment of "Not Rated."
Managed by the Natural Resources Conservation Service, Bork Number 1 plays a crucial role in water resource management in the area, particularly in controlling the flow of the TR-BADRIVER stream. While the dam's primary purpose is not specified, its construction and operation are overseen by state and federal agencies to ensure its safety and functionality. Despite being non-USACE-owned, Bork Number 1 remains a significant structure in the region, contributing to flood control and water supply management efforts.
As a key component of the local water infrastructure, Bork Number 1 serves as a testament to the collaborative efforts between private owners and regulatory agencies in safeguarding water resources and mitigating climate-related risks. With its strategic location and design, this dam stands as a vital resource in maintaining water quality and quantity in Jones, South Dakota, reflecting a commitment to sustainable water management practices.

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.
