Summary
Completed in 1967, this earth-type dam stands at a height of 21.3 feet and spans 420 feet in length. Its primary purpose is for fire protection, stock, or as a small fish pond, with a storage capacity of 115 acre-feet and a normal storage level of 88 acre-feet. Situated along the Des Lacs River, the dam's spillway is uncontrolled with a width of 100 feet.
Despite its low hazard potential, the dam's risk assessment is rated as moderate (3). With state regulation, inspection, and enforcement in place by NDSWC, Nelson-Landers Dam remains a crucial part of water resource management in the region. Although not currently rated for its condition, the dam's last inspection was conducted in May 2013 and it has not been modified in recent years. The dam does not have any outlet gates, and its emergency action plan status and risk management measures are not specifically documented.
Enthusiasts interested in water resources and climate will find Nelson-Landers Dam an intriguing structure due to its historical significance, design features, and role in providing essential services such as fire protection and water storage. With its location on the Des Lacs River and the potential risks associated with its operation, the dam presents a case study for understanding the complex interplay between infrastructure, natural systems, and regulatory oversight in managing water resources in North Dakota.

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.
