Summary
Built in 1968 by the USDA NRCS, this earth dam stands at a height of 24 feet and has a storage capacity of 105 acre-feet. The primary purpose of Galde Dam is for recreation, providing a surface area of 10.1 acres for visitors to enjoy.
Despite being classified as having a low hazard potential, Galde Dam is regulated by the North Dakota State Water Commission and undergoes regular inspections and enforcement measures. The dam features an uncontrolled spillway with a width of 75 feet, ensuring safe discharge during high water events. With a moderate risk assessment rating of 3, the dam is equipped with emergency action plans and appropriate risk management measures in place.
For water resource and climate enthusiasts, Galde Dam presents an interesting case study of a privately owned recreational structure that plays a vital role in managing water resources and providing outdoor recreational opportunities. Its location on the Sheyenne River and its design by the USDA NRCS showcase the intersection of engineering, environmental stewardship, and public enjoyment. With its low hazard potential and moderate risk assessment, Galde Dam serves as a model for responsible dam management in the state of 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.
