Summary
Completed in 1959, this earth dam stands at a height of 21 feet and has a storage capacity of 78 acre-feet, with a normal storage level of 51 acre-feet. Managed by the South Dakota Department of Environment and Natural Resources (DENR), the dam is regulated, inspected, and enforced by the state to ensure its safety and compliance with regulations.
This low hazard potential dam is not currently rated for its condition and does not have an emergency action plan in place. While it has not been modified in recent years, the dam's max discharge capacity is recorded at 2142 cubic feet per second. The Federal agency involved in the design of Vik Number 1 is the Natural Resources Conservation Service, indicating a collaborative effort between private and government entities to manage water resources effectively in the region.
As a critical infrastructure for water resource management in the area, Vik Number 1 plays a crucial role in flood control and water supply management. With its strategic location along the White River, this dam serves as a vital component in the overall water management system, highlighting the importance of proper regulation and maintenance to ensure its long-term functionality and safety for the surrounding community and environment.

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.
