Summary

Completed in 2010, this earth-type dam stands at a height of 15 feet and has a structural height of 19 feet, with a length of 295 feet. The dam has a storage capacity of 92.8 acre-feet and serves as a vital resource for the surrounding area.

Situated on the Heart River-TR, Fitterer Dam plays a crucial role in water resource management and protection in Morton County. With a low hazard potential and a moderate risk assessment, the dam is regulated by the NDSWC and undergoes regular state inspections and enforcement. The spillway type is uncontrolled with a width of 55 feet, ensuring proper water flow and management during high water events.

Despite not having a condition rating, Fitterer Dam remains a key infrastructure for the community, providing essential services for fire protection, agriculture, and wildlife habitat. With its strategic location and design, the dam contributes to the overall water resource management efforts in the region, highlighting the importance of sustainable infrastructure for climate resilience and conservation.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
