Summary

Built in 1965, this earth dam stands at a height of 10 feet and spans a length of 500 feet, with a primary purpose of serving as an offstream storage for Bassett Creek. With a maximum storage capacity of 50 acre-feet and normal storage of 25 acre-feet, this dam plays a vital role in managing water resources in the area.

Despite its low hazard potential, the Thomasville Sewer Lagoon Dam has not been rated for its current condition. While it does not fall under state jurisdiction or regulation, the dam's emergency action plan status is unclear, raising questions about its preparedness for potential risks. With no recent inspection data available, it is essential for local authorities to prioritize the assessment and maintenance of this infrastructure to ensure its continued reliability in the face of potential climate challenges.

As water resource and climate enthusiasts, it is important to monitor and advocate for the proper management and maintenance of structures like the Thomasville Sewer Lagoon Dam. By staying informed about its condition and advocating for proactive measures to address any potential risks, we can help safeguard our water resources and ensure the resilience of critical infrastructure in the face of changing environmental conditions.

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.
