Summary
Built in 1976 by USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and as a small fish pond. With a height of 21 feet and a length of 450 feet, Fiest Dam has a storage capacity of 110 acre-feet and a surface area of 7 acres.
The dam is regulated by the North Dakota State Water Commission (NDSWC) and is classified as having a low hazard potential. Despite not being rated for condition assessment, Fiest Dam has a moderate risk assessment score of 3 out of 5. The spillway, which is uncontrolled, has a width of 31 feet. The dam's location on Porcupine Creek and its drainage area of 1.8 square miles make it a crucial water resource for the surrounding area.
Although Fiest Dam does not have outlet gates or locks, its primary purpose of fire protection and stock watering highlights its importance for local agricultural and environmental needs. With its relatively low hazard potential and moderate risk assessment, the dam remains a vital infrastructure for water management in the region, ensuring the safety and sustainability of water resources for both human and ecological use.

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.
