Summary
With a height of 25 feet and a storage capacity of 54 acre-feet, this dam impounds water from TR-LOST CREEK and covers a surface area of 4 acres. Despite not being state-regulated or inspected, the dam has a high hazard potential, making it crucial for proper maintenance and emergency preparedness.
The dam, built with a buttress core type and an unlisted/unknown foundation, poses a potential risk that is yet to be fully assessed and managed. With no designated inspection frequency or condition assessment, stakeholders should consider the importance of conducting regular evaluations and developing an emergency action plan to ensure the safety of the surrounding community in case of a dam failure. As climate change continues to impact water resources, the resilience and sustainability of structures like Oetting Lake Dam become increasingly critical.
As enthusiasts of water resources and climate, it is essential to advocate for the proper monitoring and maintenance of dams like Oetting Lake Dam. By raising awareness about the potential risks associated with high hazard dams and promoting proactive measures such as risk assessments, emergency action plans, and regular inspections, we can help mitigate the impact of climate change on our water infrastructure and safeguard our communities against potential disasters.

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.
