Summary
Built in 1968 by USDA NRCS, the dam has a height of 24 feet and a length of 300 feet, creating a storage capacity of 63 acre-feet. With a surface area of 5 acres and draining an area of 0.47 square miles, the dam is regulated by the North Dakota State Water Commission and is subject to state permitting, inspection, and enforcement.
The dam features an uncontrolled spillway with a width of 35 feet and has a low hazard potential, with a moderate risk assessment rating. Despite not having a condition assessment rating, the dam is considered to be in good condition. It does not have outlet gates and is not associated with any other structures. Holm Dam serves as a vital resource for the local fish and wildlife population, contributing to the conservation efforts in the area.
Located in the Long Creek watershed and managed by a private owner, Holm Dam; Alfred H 2 stands as a testament to the importance of water resource management and climate resilience in North Dakota. As a key feature of the local ecosystem, the dam plays a crucial role in supporting biodiversity and maintaining the environmental balance in the region. With its strategic design and regulatory oversight, Holm Dam exemplifies the collaborative efforts needed to ensure the sustainable use of water resources for future generations.

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.
