Summary
With a height of 18.8 feet and a length of 300 feet, the dam provides a storage capacity of 90 acre-feet and covers a surface area of 24 acres. It is situated on the Haynes Creek-TR river/stream and falls under the jurisdiction of the New Jersey Department of Environmental Protection (NJDEP), with state regulation, permitting, inspection, and enforcement in place.
The dam's primary purpose is recreation, offering opportunities for activities such as fishing, boating, and wildlife observation in the surrounding area. Despite its high hazard potential, Timber Lake Dam has been assessed as satisfactory in condition, with the last inspection conducted in May 2021. The Emergency Action Plan (EAP) status and risk assessment for the dam are currently unknown, with no specific risk management measures or inundation maps prepared at this time.
With its scenic location and recreational opportunities, Timber Lake Dam serves as an important water resource and climate feature in the region. As enthusiasts and stakeholders continue to monitor its condition and safety measures, the dam remains a focal point for outdoor enjoyment and environmental conservation efforts in Medford Township, New Jersey.

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.
