Summary
With a height of 34 feet and a storage capacity of 618 acre-feet, this dam serves as a picturesque spot for water enthusiasts in the Warren County area. Situated on TR Little Lost Creek, the dam offers a tranquil environment for visitors to enjoy various water activities.
Despite its recreational benefits, Bumb Lake #1 Dam poses a high hazard potential and has not been rated for its condition assessment. With no state regulatory oversight or inspection in place, the dam's safety and maintenance rely solely on the private owner. As such, it is crucial for water resource and climate enthusiasts to stay informed about the dam's status and potential risks, as well as to advocate for proper maintenance and oversight to ensure the safety of both the dam and its surrounding environment.
In the absence of state jurisdiction and regulatory agencies, the responsibility for monitoring and managing Bumb Lake #1 Dam falls on the private owner. It is essential for water resource and climate enthusiasts to raise awareness about the importance of regular inspections, emergency preparedness, and risk management measures to mitigate any potential hazards associated with the dam. By staying informed and advocating for proper maintenance and oversight, enthusiasts can help safeguard the integrity of this recreational water resource for future generations to enjoy.

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.
