Summary
Completed in 1987, this earth dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 12 feet and a length of 200 feet, the dam has a storage capacity of 51.4 acre-feet and covers a surface area of 6.7 acres. It is regulated by the North Dakota State Water Commission (NDSWC) and is equipped with an uncontrolled spillway that is 100 feet wide.
Despite its low hazard potential and moderate risk assessment, Dvorak Dam has not been inspected since October 2000, with its condition currently marked as "Not Rated". The dam is not equipped with outlet gates and does not have an Emergency Action Plan (EAP) in place. Although its risk management measures are unspecified, it remains under state jurisdiction and is subject to regular permitting, inspection, and enforcement by the NDSWC. Situated on Crooked Creek-TR, this dam plays a crucial role in water resource management and ecosystem support within the region.
For water resource and climate enthusiasts, Dvorak Dam presents a unique opportunity to study a privately owned structure that contributes to the local ecosystem's health and sustainability. As one of the many dams in North Dakota regulated by state agencies, Dvorak Dam highlights the importance of regular inspection, maintenance, and risk assessment to ensure the safety and functionality of such water infrastructure. Its role in providing fire protection, stock watering, and recreational opportunities underscores the diverse benefits that well-managed dams can offer to both humans and wildlife in the area.

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.
