Summary
Standing at a height of 26 feet and boasting a storage capacity of 167 acre-feet, this dam plays a crucial role in providing water resources for the local area. The dam is situated on TR Little Lost Creek and is not regulated by the state, with a high hazard potential due to its proximity to residential areas.
Despite not being state regulated, Hambauch Lake Dam serves as a vital resource for fire protection, recreation, and water storage in the region. The dam's condition assessment is currently not rated, and the last inspection date is unavailable. With its significant storage capacity of 167 acre-feet and a surface area of 12 acres, the dam plays an essential role in managing water resources in the area. While there is no emergency action plan prepared or updated for the dam, its presence is crucial for maintaining water security and supporting various uses in the community.
Owned privately, Hambauch Lake Dam serves as a key structure for water management in the region, with a focus on fire protection and recreational purposes. The dam's location on TR Little Lost Creek and its high hazard potential highlight the importance of regular inspections and maintenance to ensure its structural integrity. As a valuable asset for water storage and recreational activities, this dam plays a significant role in the local ecosystem and community resilience against climate impacts.

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.
