Summary
The dam, with a height of 17 feet and a length of 339 feet, serves primarily as a Fish and Wildlife Pond. It has a storage capacity of 123 acre-feet and a drainage area of 3.13 square miles, with a spillway width of 100 feet and uncontrolled spillway type. The lake is regulated by the North Dakota State Water Commission and undergoes regular inspections, with a low hazard potential and a moderate risk assessment rating.
Known also as M Mosbrucker, Mosbrucker Lake is situated near Sweetbriar Creek-TR and is managed for fish and wildlife conservation purposes. While the dam is not USACE-owned, it is state-regulated and permitted, with enforcement and inspection procedures in place. The surrounding area does not have inundation maps prepared, but the dam is considered to have moderate risk management measures in place, with a condition assessment of "Not Rated". The lake is a vital resource for the local ecosystem and presents a low hazard potential to the area.
For water resource and climate enthusiasts, Mosbrucker Lake offers a fascinating glimpse into the intersection of human engineering and environmental conservation. With its stone core and soil foundation, the Earth dam showcases the importance of sustainable water management practices. As a Fish and Wildlife Pond, it provides a habitat for various species and contributes to the biodiversity of the region. With its low hazard potential and moderate risk assessment, the lake serves as a prime example of responsible dam construction and maintenance in the face of changing climate patterns.

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.
