Summary
With a height of 12 feet and a length of 600 feet, the dam has a storage capacity of 106 acre-feet and a surface area of 17 acres. It is situated on Copperas Creek and is under the jurisdiction of the Galveston District of the US Army Corps of Engineers.
Despite being privately owned and not regulated by the state, Macon Lake Dam poses a high risk due to its condition assessment being not rated and its hazard potential being not available. The dam does not have a spillway and is equipped with one outlet gate. Although no recent inspection data is available, the dam is marked as requiring state permitting and inspection, indicating that it must adhere to certain safety standards.
For water resource and climate enthusiasts, Macon Lake Dam serves as an interesting case study of a privately owned structure with potential risks. The lack of available data on its condition and hazard potential highlights the importance of regular inspections and maintenance to ensure the safety of such infrastructure. Further research and monitoring of Macon Lake Dam could provide valuable insights into the management and regulation of private dams in the US.

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.
