Summary
Built in 1922, this earth dam, designed by HDR, serves the primary purpose of water supply for the surrounding area. With a height of 23 feet and a length of 1750 feet, the dam holds a maximum storage capacity of 1188 acre-feet, providing crucial water resources to the region.
The dam's connection to Big Sandy Creek underscores its importance in regulating water flow and ensuring sustainable water management practices. Despite its age, the dam continues to play a vital role in the community. However, recent assessments have deemed its condition unsatisfactory, highlighting the need for ongoing maintenance and risk management measures to ensure its long-term viability in the face of evolving climate challenges.
With a moderate risk assessment rating, stakeholders must prioritize safety and resilience measures to address any potential hazards associated with the dam. Regular inspections and maintenance are essential to safeguard the surrounding area from the impacts of dam failure. By staying proactive and implementing necessary risk management strategies, Marlin Old City Lake Dam can continue to serve as a vital water resource for the community while adapting to the changing climate landscape.

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.
