Summary
Built in 1938, this earth dam stands at a height of 8 feet and spans 150 feet in length, with a storage capacity of 4 acre-feet. Situated on the Timber Creek North Branch, this dam is regulated by the New Jersey Department of Environmental Protection and undergoes regular inspections to ensure compliance with state regulations.
Despite its significant hazard potential and poor condition assessment, Bottom's Lake Dam plays a crucial role in water resource management in Camden County. With a maximum discharge capacity of 650 cubic feet per second, this dam serves as a vital infrastructure for flood control and water storage in the region. However, its condition raises concerns about the need for immediate maintenance and potential risk mitigation measures to ensure the safety and reliability of the structure.
As climate change impacts water resources and infrastructure resilience, Bottom's Lake Dam serves as a focal point for discussions on adaptive strategies and risk management in the face of evolving environmental challenges. Stakeholders, including local authorities and water resource enthusiasts, are called upon to prioritize the safety and sustainability of this essential dam to safeguard communities and ecosystems in the region for future generations.

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.
