Summary
This dam, standing at a height of 20.4 feet and a length of 305 feet, has a storage capacity of 132.2 acre-feet and a surface area of 14.1 acres. The dam is regulated by the NDSWC and is subject to state permitting, inspection, and enforcement.
Situated on Scab Creek, Doll Dam serves as a crucial water resource for the surrounding area, providing essential fire protection and stock water. Despite its low hazard potential, the dam is considered to have a moderate risk level, highlighting the importance of proper risk management measures. With its stone core and soil foundation, the dam represents a sustainable and resilient infrastructure for water storage and management in the region.
Water resource and climate enthusiasts will appreciate Doll Dam's contribution to local water supply and its role in supporting wildlife and agricultural activities. As a privately owned structure with state regulation and oversight, Doll Dam exemplifies the partnership between government agencies and private entities in ensuring the safety and sustainability of water infrastructure. Its completion in 2012 marked a significant milestone in enhancing water security and resilience in North Dakota, making Doll Dam a valuable asset in the region's water resource management efforts.

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.
