Summary
Built in 1934 by USFWS, this earth dam stands at a height of 15 feet and has a length of 670 feet. The primary purpose of Jung Lake Dam is to serve as a Fish and Wildlife Pond, providing essential habitat for local wildlife.
This dam, situated on Coal Bank Creek, has a storage capacity of 644 acre-feet and a surface area of 56.2 acres. It is state-regulated by the North Dakota State Water Commission (NDSWC), ensuring that it meets all necessary safety and environmental standards. The dam features an uncontrolled spillway with a width of 120 feet and vertical lift outlet gates for water management.
With a low hazard potential and a moderate risk rating, Jung Lake Dam plays a crucial role in supporting the surrounding ecosystem while also posing minimal risk to nearby communities. While the condition assessment is currently not rated, the dam is regularly inspected and maintained to ensure its continued safety and functionality.

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.
