Summary
This private earth dam stands at a height of 32 feet and has a storage capacity of 34 acre-feet. Situated on TR Little Lost Creek, the dam encompasses a surface area of 2 acres and serves a drainage area of 63 square miles. Despite its small size, Bumb Lake Dam #3 has a high hazard potential, making it crucial for proper maintenance and monitoring.
Owned and operated by a private entity, this dam has not been rated for its condition assessment, and its emergency action plan status remains unknown. With no state regulation or inspection, the responsibility for the safety and upkeep of Bumb Lake Dam #3 falls solely on its private owner. Given its high hazard potential and lack of recent inspection data, water resource and climate enthusiasts should pay attention to this dam and advocate for proper safety measures to protect the surrounding community and ecosystem from potential risks associated with dam failure.
As a part of the St. Louis District, US Army Corps of Engineers, Bumb Lake Dam #3 may benefit from increased federal oversight and funding for maintenance and safety improvements. Climate change and extreme weather events further underline the importance of ensuring the resilience of dams like Bumb Lake Dam #3 in the face of evolving environmental challenges. By staying informed and advocating for proper management of this dam, enthusiasts can contribute to the protection of water resources and the mitigation of climate-related risks in their local community.

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.
