Summary
This Earth-type dam serves as a Fish and Wildlife Pond with a normal storage capacity of 11.7 acres and a maximum storage of 103.2 acres. The dam is situated on the Cannonball-TR river and is regulated by the North Dakota State Water Commission, with state permitting, inspection, and enforcement in place.
With a height of 8.3 feet and a length of 662 feet, Schneider Dam has a low hazard potential and a moderate risk assessment rating. The dam features an uncontrolled spillway with a width of 150 feet and is primarily made of stone and soil foundations. Despite not being rated for condition assessment, the dam meets state jurisdiction and regulatory standards for operations and maintenance.
Overall, Schneider Dam plays a vital role in providing water resource management for fish and wildlife in the area. Its strategic location and design contribute to the conservation efforts in North Dakota, making it an essential asset for climate and water resource enthusiasts to appreciate and support.

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.
