Summary
Built in 1959, this earth dam stands at a height of 23 feet and stretches 530 feet in length. Its primary purposes include fire protection, stock, and serving as a small fish pond, with a normal storage capacity of 55.4 acre-feet.
Managed by the North Dakota State Water Commission, Wells Dam poses a low hazard potential and has a moderate risk assessment rating. The spillway, which is uncontrolled, has a width of 100 feet. While the dam has not been rated for its condition, it is inspected, permitted, and regulated by the state authorities. The dam's location on Pitt Creek-TR contributes to its drainage area of 4.1 square miles.
Water resource and climate enthusiasts may find Wells Dam to be an intriguing subject of study due to its historical significance and role in providing water management solutions in the area. Its design by the Soil Conservation Service and its association with fire protection and stock management add layers of interest to this structure. With its low hazard potential and moderate risk assessment, Wells Dam stands as a testament to responsible dam construction and management practices in North Dakota.

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.
