Summary
Completed in 1945, this earth dam stands at 15 feet high and spans 925 feet in length, with a storage capacity of 90 acre-feet for irrigation purposes. Situated on the Horse Creek-TR river or stream, this significant dam has a spillway width of 65 feet and is classified as having a moderate risk level (3) according to the risk assessment.
Owned and regulated by the North Dakota State Water Commission (NDSWC), Derudder Dam is subject to state permitting, inspection, and enforcement. With a primary purpose of irrigation, this dam serves as a vital water resource for the surrounding area. Despite its significant hazard potential and lack of a condition assessment rating, it plays a crucial role in managing water flow and storage in the region.
While Derudder Dam has not been modified in recent years and lacks certain emergency preparedness measures such as an Emergency Action Plan (EAP) and inundation maps, it remains a key infrastructure for water management in North Dakota. With its stone core and soil foundation, this private earth dam continues to support agricultural activities and water supply needs in the area, highlighting the importance of sustainable water resource management in the face of changing climate conditions.

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.
