Sioux Lake Dam dam
Sioux Lake Dam
Sioux Lake Dam, located in Medford, New Jersey, stands as a private structure regulated by the NJDEP. 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. With a commitment to maintaining its structural integrity and safeguarding against potential hazards, the dam remains a focal point for water resource and climate enthusiasts seeking to understand the intersection of infrastructure, regulation, and environmental stewardship in the local community.

Condition Assessment
- Satisfactory
- No 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.
- 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.
- 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.
Hazard Potential Classification
- High
- Dams 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, environmental 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.

About Sioux Lake Dam
Where does the data for Sioux Lake Dam come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
