Summary
Managed by Toman Engineering, the dam stands at a height of 24 feet and has a storage capacity of 58.23 acre-feet across a surface area of 6.47 acres. With a low hazard potential, the dam has a controlled spillway and a single vertical lift outlet gate.
Regulated by the North Dakota State Water Commission (NDSWC), Olander Dam; Brian is inspected, permitted, and enforced by state authorities. Despite not having a current condition rating, the dam is deemed to have a very high risk level, requiring risk management measures to ensure public safety. Situated on the Missouri River tributary, the dam plays a crucial role in water resource management and ecosystem conservation in the region.
As a vital structure for water resource management in the area, Olander Dam; Brian serves multiple purposes and highlights the importance of private owners in contributing to climate resilience. With its strategic location and design features, the dam provides a valuable water source for fire protection and livestock, while also supporting biodiversity through its function as a small fish pond. The dam's risk assessment underscores the need for proactive measures to mitigate potential hazards and safeguard the surrounding community and environment.

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.
