Summary
This private-owned structure serves primarily for recreation purposes, offering a serene environment for water enthusiasts to enjoy various activities. The dam, built with earth and buttress core types, has a height of 18 feet and spans 925 feet along the Ryo Creek.
With a storage capacity of 223 acre-feet and a normal storage of 160 acre-feet, the dam provides essential water resources for the surrounding area. Although lacking a spillway, the structure is well-maintained and inspected regularly to ensure its safety and stability. Despite being classified as having a high risk potential, the Martin Lake Dam continues to be a vital asset for the community, offering both leisure and water management benefits.
For water resource and climate enthusiasts, the Martin Lake Dam serves as a fascinating example of sustainable engineering practices. This historic structure not only provides recreational opportunities but also plays a crucial role in water storage and management in the region. With a rich history dating back to the 1930s, the dam stands as a symbol of resilience and innovation in the face of changing environmental conditions.

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.
