Summary
The dam, completed in 1997, stands at a height of 10 feet and has a storage capacity of 220 acre-feet. With a normal storage capacity of 135.1 acre-feet and a surface area of 70 acres, the pond serves as a crucial habitat for local wildlife and contributes to the overall conservation efforts in the area.
Managed by the USFWS and DU, Moen Wpa is regulated by the North Dakota State Water Commission, ensuring that the pond meets necessary inspection, enforcement, and permitting requirements. The low hazard potential and moderate risk assessment make Moen Wpa a reliable resource for water management and conservation. The dam's uncontrolled spillway, vertical lift outlet gates, and stone core foundation further highlight its functionality and adherence to safety standards.
The location's proximity to Shell Creek and its inclusion in the St. Paul District underscore the interconnectedness of water resources in the region. With its historical significance dating back to the late 20th century, Moen Wpa represents a harmonious balance between human intervention and environmental preservation, making it a valuable asset for water resource and climate enthusiasts alike.

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.
