Summary

Completed in 2010, this earth dam stands at a height of 17.7 feet, with a dam length of 635 feet. The primary purpose of the dam is to provide fire protection and water storage, with a normal storage capacity of 55.9 acre-feet and a maximum storage of 224 acre-feet.

The dam is situated on Sweet Briar Creek-TR and is regulated by the North Dakota State Water Commission (NDSWC). With a low hazard potential and a moderate risk assessment rating of 3, Schlosser Dam has not been rated for condition assessment. The spillway type is uncontrolled, with a spillway width of 60 feet, and the dam has not been modified since its completion. While the dam has not been inspected recently, it is subject to state permitting, inspection, and enforcement.

Despite its small size and relatively low hazard potential, Schlosser Dam plays a crucial role in providing fire protection and water storage in the region. As climate change continues to impact water resources, dams like Schlosser will become even more essential in managing water supply and protecting against potential hazards. Climate and water resource enthusiasts can appreciate the significance of structures like Schlosser Dam in maintaining water security and resilience in the face of a changing climate.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
