Summary
Standing at a height of 27 feet with a length of 339 feet, this earth dam serves multiple purposes including fire protection, stock, small fish pond, and grade stabilization. With a normal storage capacity of 24 acre-feet and a maximum storage of 36 acre-feet, the dam covers a surface area of 15 acres and drains an area of 585 square miles.
Despite being classified as having a low hazard potential, Martin Dam is considered to have a moderate risk level. It features an uncontrolled spillway with a width of 10 feet and does not have any outlet gates. While the condition assessment is not rated, the structure has not undergone any recent modifications. With no associated structures and a lack of emergency action plan preparedness, Martin Dam remains a key feature in the local water resource management system, contributing to the overall environmental health of the area.
Water resource and climate enthusiasts will appreciate Martin Dam for its role in maintaining water levels and preventing erosion along the TR-South Wyaconda River. As a privately owned structure, it stands as a testament to the importance of responsible land management and infrastructure development in ensuring the sustainability of water resources in the region. With its multiple purposes and moderate risk level, Martin Dam represents a balance between human intervention and natural processes, highlighting the complex relationship between water management and climate resilience in the face of environmental challenges.

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.
