Summary
This earth dam stands at a height of 32 feet and stretches 450 feet in length, creating a large reservoir with a storage capacity of 58 acre-feet. The dam is primarily fed by spring water and runoff, making it a vital source of water in the region. Despite its undetermined hazard potential and not yet being rated for condition assessment, the dam serves as a key infrastructure for water resource management in the area.
With a surface area of 3.7 acres, Mathena Large Pond Dam plays a crucial role in storing and regulating water flow in the region. It is equipped with outlet gates for water release when necessary, although specific details on its spillway and discharge capacity are not provided. The dam's emergency action plan status, risk assessment, and management measures remain to be determined, highlighting the need for further evaluation and preparedness. As water resource and climate enthusiasts, it is important to monitor and assess the condition of dams like Mathena Large Pond to ensure their safety and efficiency 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.
