Summary
Built in 1998 by the North Dakota Game and Fish Department, this structure boasts a dam height of 6.5 feet and a storage capacity of 3,738 acre-feet. Its primary purpose is flood risk reduction, with the roller-compacted concrete core dam serving as a key element in protecting the surrounding area from potential inundation.
Despite its low hazard potential, Hyatt Slough Wma 2 is considered to have a very high risk due to its location and the critical role it plays in managing water levels during periods of high flow. The dam features a controlled spillway with a width of 17 feet and vertical lift outlet gates for efficient water release. While the dam's condition has not been rated, it is regularly inspected and maintained by the North Dakota State Water Commission to ensure its structural integrity and functionality. As a state-regulated and permitted structure, Hyatt Slough Wma 2 highlights the importance of proactive water resource management in mitigating flood risks and protecting communities along the James River.

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.
