Summary
Built in 1934 by the FERA, this earth dam stands at a height of 7 feet and has a length of 350 feet, with a storage capacity of 59 acre-feet. Situated on the Little Deep Creek, it is regulated by the NDSWC and falls under the jurisdiction of the state of North Dakota.
Despite its low hazard potential and moderate risk assessment, the condition of the Hamerly Dam is currently not rated. With a surface area of 10 acres and a drainage area of 18 square miles, this structure plays a crucial role in the local water management system. While it lacks certain features like outlet gates and spillway width, the dam continues to serve its purpose effectively with regular state inspections and enforcement.
Enthusiasts of water resources and climate in the region can appreciate the historical significance and functionality of the Hamerly Dam. Its role in providing essential services like fire protection and stock maintenance, as well as its minor contribution to the ecological balance through small fish pond support, showcases the importance of sustainable water management practices in maintaining a healthy environment.

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.
