Summary

Built in 2005, this earth dam stands at a height of 34.42 feet, with a hydraulic height of 36 feet and a structural height of 36 feet. It has a storage capacity of 87.1 acre-feet, with a normal storage level of 48.94 acre-feet, covering a surface area of 4.74 acres and draining a 0.28 square mile area.

Managed by a private owner, Martiny Dam is regulated by the Kansas Department of Agriculture and undergoes regular state inspections, enforcement, and permitting processes. The dam has a high hazard potential and is considered to be in fair condition, with a moderate risk assessment score of 3. Despite not having outlet gates, the dam features an uncontrolled spillway with a width of 28 feet. The surrounding area is at risk of inundation, requiring ongoing risk management measures to ensure the safety and stability of the dam.

For water resource and climate enthusiasts, Martiny Dam offers a fascinating glimpse into the intersection of human infrastructure and natural resources. With its diverse range of purposes and the potential risks associated with its high hazard rating, this dam serves as a critical piece of infrastructure in managing water resources and protecting the surrounding environment. As climate change continues to impact water availability and quality, understanding and monitoring dams like Martiny Dam becomes increasingly important for ensuring sustainable water management practices in the future.

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.
