Summary
Clark Salyer #326 Dam, located on the Souris River in North Dakota, is a Federal-owned structure managed by the US Fish and Wildlife Service. Built in 1936, this earth dam stands at a height of 13 feet and has a length of 9572 feet, with a storage capacity of 44,802 acre-feet and a surface area of 5877 acres. The dam serves the primary purpose of regulating water flow and storage for environmental conservation and wildlife management, making it a key component in the management of water resources in the region.
With a low hazard potential and fair condition assessment, the dam has been inspected regularly by the Fish and Wildlife Service to ensure its continued safety and functionality. The dam features outlet gates for controlled water release and a spillway width of 742 feet. While the dam has undergone modifications in 1992, it remains a vital piece of infrastructure for water resource management in the area, with a capacity to handle a maximum discharge of 19,267 cubic feet per second.
Overall, J. Clark Salyer #326 Dam plays a crucial role in the conservation and management of water resources in North Dakota. With its strategic location on the Souris River and its capacity to store and regulate water flow, the dam contributes to environmental protection, wildlife habitat preservation, and flood control efforts in the region. As a Federal-owned structure with state regulation and inspection, the dam exemplifies collaborative efforts to ensure the sustainable utilization of water resources amidst changing climate patterns and increasing water demands.

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.
