Summary
Completed in 1964, this earth dam stands at a hydraulic height of 28 feet and a structural height of 31 feet, with a length of 430 feet. With a storage capacity of 90 acre-feet and a drainage area of 230 square miles, Cass Lake Dam serves as a vital resource for water enthusiasts in the area.
Managed by the North Carolina Department of Environmental Quality's Dam Safety Program, Cass Lake Dam is subject to state regulation, inspection, and enforcement to ensure its safety and functionality. Despite being classified as having a low hazard potential and its condition not yet rated, the dam undergoes regular inspections every five years to maintain its integrity. Additionally, with a maximum discharge of 139 cubic feet per second, Cass Lake Dam plays a crucial role in managing water flow in Third Creek-Tr.
The dam's location along Third Creek-Tr provides not only recreational opportunities but also serves as a key component in the local water infrastructure. With its scenic surroundings and vital role in water resource management, Cass Lake Dam is a valuable asset for both the community and the environment, highlighting the intersection of water resources and climate considerations in the region.

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.
