Summary

Built in 1934 by the Civilian Conservation Corps, this dam serves multiple purposes including fire protection, stock watering, and creating a small fish pond. With a height of 11.5 feet and a storage capacity of 150 acre-feet, Nd No Name 227 plays a crucial role in managing water resources in the region.

Managed by the North Dakota State Water Commission, this dam is regulated, permitted, inspected, and enforced by state authorities to ensure its safety and functionality. Despite being classified as having a low hazard potential, Nd No Name 227 is considered to have a moderate risk level, indicating the need for ongoing risk assessment and management measures. Additionally, the dam features an uncontrolled spillway with a width of 65 feet, highlighting its design for managing water flow during periods of high discharge.

Overall, Nd No Name 227 stands as a testament to the importance of water resource management and climate resilience in the face of changing environmental conditions. With its historical significance, multiple uses, and state oversight, this dam serves as a vital infrastructure for the community of Harwood and the surrounding area, showcasing the intersection of water, climate, and human ingenuity in safeguarding our natural resources.

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.
