Summary
This Earth-type dam, completed in 1961, stands at a height of 10 feet with a length of 800 feet. The reservoir has a storage capacity of 140 acre-feet, with a normal storage level of 90 acre-feet and a drainage area of 0.75 square miles. The dam has a spillway width of 30 feet and a maximum discharge rate of 300 cubic feet per second.
Despite being classified as having a low hazard potential, Rumac has a moderate risk assessment rating of 3. The condition of the dam is currently not rated, and the emergency action plan status is unknown. The primary purpose of Rumac is for fish and wildlife habitat, with additional purposes including fire protection and small fish pond. Although not regulated by the state, this reservoir serves as a valuable resource for the local ecosystem and surrounding community. Climate and water resource enthusiasts will find Rumac’s history and design characteristics intriguing for further study and appreciation of its environmental impact.

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.
