Summary
Built in 1937 by the Works Progress Administration (WPA), this dam serves primarily for recreational purposes and offers a storage capacity of 285 acre-feet. With a height of 15.2 feet and a length of 160 feet, the dam contributes to the scenic beauty and water management in the area.
Managed by the local government and regulated by the North Dakota State Water Commission, Hillsboro Dam has a low hazard potential and is currently not rated for its condition assessment. Although it does not have outlet gates, the spillway width of 100 feet allows for controlled release of water during high flow events. The risk assessment for this dam indicates a moderate level of risk (3), prompting the need for ongoing monitoring and potential risk management measures to ensure the safety and integrity of the structure.
Despite its age, Hillsboro Dam continues to provide essential recreational opportunities and water resource management benefits to the community. With its historical significance and connection to the WPA era, this dam serves as a reminder of the importance of sustainable water infrastructure for both local residents and climate enthusiasts alike.

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.
