Summary

Constructed in 1991 by HARZA ENGINEERING, this Earth-type dam stands at 10 feet high with a structural height of 90 feet, and a length of 690 feet. It serves the primary purpose of hydroelectric power generation, with a storage capacity of 23,500 acre-feet and a surface area of 604 acres.

Situated along Heath Creek and the Armuchee River, Rocky Mtn Dam B plays a crucial role in water resource management and energy production in the region. Despite its low hazard potential, the dam is subject to federal regulatory oversight by the Federal Energy Regulatory Commission, ensuring its safe operation and maintenance. With a risk assessment rating of High (2), the dam undergoes regular inspections and emergency action plan updates to mitigate potential risks and ensure public safety.

As a key component of Georgia's water infrastructure, Rocky Mtn Dam B contributes to the local economy and environmental sustainability through renewable energy generation. Its strategic location and efficient design make it a vital asset for water resource and climate enthusiasts interested in the intersection of hydroelectric power, dam safety, and environmental stewardship in the Rocky Mountain region.

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.
