Summary
Built in 1995 by the USFWS, this earth-type dam serves multiple purposes including fire protection, stock, and small fish pond management. With a height of 9.4 feet and a length of 602 feet, the dam has a storage capacity of 69.6 acre-feet and a surface area of 8.2 acres, making it an essential resource for the local community.
Managed by the NDSWC, Dohrmann Dam has a low hazard potential and a moderate risk assessment rating of 3. Despite not having a current condition rating, the dam is inspected, permitted, and regulated by the state, ensuring its safety and functionality. The spillway, which is uncontrolled, has a width of 300 feet, providing adequate discharge capacity in case of excess water flow. With no outlet gates and minimal associated structures, Dohrmann Dam remains a reliable asset for water resource and climate enthusiasts in the region.
In the event of an emergency, the dam's Emergency Action Plan (EAP) status is currently unknown, highlighting the importance of regular updates and preparedness measures. While the dam's risk management measures and inundation maps are not specified, its role in providing vital services such as fire protection and stock management underscores its significance in the local ecosystem. As a key component of the Deep Creek-TR watershed, Dohrmann Dam continues to be a valuable asset for both the community and the environment.

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.
