Summary
Built in 1994, this earth dam stands at a height of 23 feet and has a storage capacity of 58.2 acre-feet. With a surface area of 2.6 acres and a drainage area of 0.11 square miles, this wetland serves as a crucial habitat for local wildlife.
Managed by the North Dakota State Water Commission, Glenharold Mine Coyote Way 4 has a low hazard potential and is currently in a not rated condition assessment. The spillway for this structure is uncontrolled, and it has no outlet gates. Despite its moderate risk level, the pond has not been inspected recently, and there is no emergency action plan in place. As a key feature in the local ecosystem, maintaining the integrity of this wetland is essential for preserving the surrounding environment and supporting biodiversity.
Water resource and climate enthusiasts can appreciate Glenharold Mine Coyote Way 4 for its role in providing a sustainable habitat for fish and wildlife in the North Dakota region. With its earth dam construction and stone core, this wetland serves as a conservation area that contributes to the overall health of the local ecosystem. While the structure is currently in a fair condition, ongoing monitoring and maintenance are necessary to ensure the continued functionality and safety of this important water resource.

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.
