Summary
Designed by USFWS, this structure serves multiple purposes including fire protection, stock, and small fish pond. The dam stands at a height of 15.5 feet, with a NID height of 16 feet and a length of 470 feet. It has a storage capacity of 125.6 acre-feet and a surface area of 11 acres, serving as a critical water resource for the surrounding area.
The dam is regulated by the North Dakota State Water Commission and is inspected regularly to ensure its safety and functionality. With a low hazard potential and a moderate risk assessment rating, Diede Dam plays a crucial role in water management and emergency preparedness in the region. Despite not being rated for its condition, the dam continues to provide valuable water storage and control capabilities for the community.
Located along the Scab Creek-TR river or stream, Diede Dam is an essential infrastructure for water resource management in the area. With its primary purpose of fire protection and stock maintenance, this earth dam contributes to the overall resilience of the region's water supply. As climate change continues to impact water availability and quality, structures like Diede Dam become increasingly important for sustainable water management practices.

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.
