Summary
Pd #005, also known as Glenharold Mine, is a privately owned fish and wildlife pond located in North Dakota's Mercer County. The dam, completed in 1984, stands at a height of 25.4 feet and has a storage capacity of 295 acre-feet. The primary purpose of this earth dam is to provide habitat for fish and wildlife, with a surface area of 7 acres and a drainage area of 1.59 square miles.
The dam is regulated by the North Dakota State Water Commission (NDSWC) and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating of 3. The spillway, classified as uncontrolled, has a width of 30 feet, and there is a single valve outlet gate for water release. Although the condition assessment is currently not rated, the dam is considered to meet guidelines for emergency action plans, with emergency contacts updated and inundation maps prepared.
Overall, Consolidation Coal Co. Pd #005 serves as an important resource for wildlife in the region, with a focus on conservation and habitat enhancement. The dam's construction and management align with state regulations and enforcement measures, ensuring the safety and functionality of the facility for both ecological and recreational purposes. With a commitment to risk management and emergency preparedness, this dam contributes to the sustainable management of water resources in the area, making it a valuable asset for water resource and climate enthusiasts.

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.
