Summary
Completed in 1940, this dam serves the primary purpose of creating a Fish and Wildlife Pond, with a storage capacity of 112.1 acre-feet. The dam has a height of 15 feet and a length of 670 feet, with a surface area of 12.5 acres and a drainage area of 2.72 square miles.
Managed by the North Dakota State Water Commission, Schmidt Dam is regulated, inspected, and enforced by state authorities to ensure its safety and functionality. With an uncontrolled spillway and a low hazard potential, the dam poses a moderate risk to the surrounding area. Despite being last inspected in 2000 and not being rated for its condition, the dam continues to provide essential water resources for fish and wildlife in the region.
Located along Crooked Creek-TR, Schmidt Dam plays a crucial role in water management and conservation efforts in North Dakota. With its stone core and soil foundation, the dam stands as a testament to the importance of sustainable water resource management in the face of changing climate patterns and increasing environmental challenges.

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.
