Lake Kathryn South Dam dam
Lake Kathryn South Dam
Lake Kathryn South Dam, located in Sussex, New Jersey, is a private earth dam primarily used for recreation purposes. With a height of 10 feet and a length of 200 feet, the dam holds a normal storage capacity of 84 acre-feet and covers a surface area of 12 acres. The dam is regulated by the New Jersey Department of Environmental Protection and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite being classified as low hazard potential, the condition of Lake Kathryn South Dam is currently not rated. The last inspection date was recorded in January 2000, with a scheduled inspection frequency of 4 years. While emergency action plans and risk assessments are not specified in the data, the dam's location in Stillwater Township and its association with a small branch river make it an important water resource for the surrounding area. Additionally, the dam falls under the jurisdiction of Congressional District 05 in New Jersey, represented by Josh S. Gottheimer.
Overall, Lake Kathryn South Dam serves as a vital recreational resource in Sussex County, offering water-based activities and scenic views for visitors and residents alike. As a privately owned structure, the dam plays a crucial role in water management and conservation efforts in the region. With its regulated status and regular inspections, Lake Kathryn South Dam continues to provide a safe and enjoyable environment for water enthusiasts and climate advocates to appreciate and protect.

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.
Plan around the weather

About Lake Kathryn South Dam
Where does the data for Lake Kathryn South 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 Low 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.
