Beach Dam Reservoir Report
Nearby: Knight Dam Uekert Dam; E. E.
Last Updated: March 24, 2026
Beach Dam, located in Beach, North Dakota, was completed in 1957 for the primary purpose of recreation along the Beaver Creek-TR river.
Summary
Managed by the local government, this earth dam stands at 17 feet high with a storage capacity of 93 acre-feet. While its spillway is uncontrolled with a width of 60 feet, the dam is classified as having a high hazard potential and poor condition assessment.
Despite its risk assessment rating of moderate, Beach Dam remains a popular spot for water resource and climate enthusiasts to explore. With a history dating back over six decades, this structure serves as a reminder of the importance of proper maintenance and inspection to ensure the safety of both the dam and surrounding communities. As a focal point of outdoor recreation in Golden Valley, North Dakota, Beach Dam continues to draw visitors seeking to enjoy the beauty of the area and the benefits of its reservoir.

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.
