Summary
This earth dam, constructed in 1975 by USDA NRCS, stands at a height of 22 feet and has a length of 184 feet. With a storage capacity of 56 acre-feet, it primarily regulates water from the North Fork Creek within a drainage area of 1.03 square miles.
Managed by a private owner, Johnsrud Dam is regulated by the North Dakota State Water Commission and undergoes regular inspections, enforcement, and permitting processes. The dam has a low hazard potential and is not currently rated for condition assessment. Despite being uncontrolled, the spillway has a width of 25 feet, ensuring effective water release during high flow events. The risk assessment for the dam is moderate, indicating a level 3 risk rating.
Overall, Johnsrud Dam plays a crucial role in water resource management in the region, providing essential services for fire protection, agricultural activities, and ecological conservation. As climate change impacts continue to influence water availability and quality, the maintenance and monitoring of dams like Johnsrud are essential to ensure sustainable water use for both human and environmental needs in the future.

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.
