With a primary purpose of recreation, this earth dam boasts a height of 12 feet and a length of 300 feet, creating a surface area of 2 acres and draining an area of 0.2 square miles. The dam has been assessed as satisfactory in condition, with a significant hazard potential, prompting inspections every two years to ensure its safety and reliability.
Situated in Burlington County, Sioux Lake Dam overlooks Haynes Creek-TR and serves as a vital source of recreational enjoyment for residents and visitors alike. Despite the absence of federal agency ownership or funding, the dam remains under state jurisdiction and regulation, adhering to strict permitting, inspection, and enforcement protocols set forth by the NJDEP. With no recorded modifications or emergency action plans in place, the dam's operational integrity and hazard management measures warrant continued attention and oversight to ensure public safety and environmental protection in the region.
As a key component of the Medford Lakes Borough landscape, Sioux Lake Dam represents a significant recreational asset with the potential for enhanced risk assessment and management strategies in the future.

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.
