John Surgeon Pond Dam dam
John Surgeon Pond Dam
John Surgeon Pond Dam, also known as Surgeon Pond, is a privately owned structure located in Nutwood, Illinois. Constructed in 1970 by the USDA NRCS, this earth dam stands at a height of 25 feet and stretches 250 feet in length, with a storage capacity of 56 acre-feet. The dam serves multiple purposes, including recreation and other activities, and is regulated by the Illinois Department of Natural Resources.
Situated on TR- Sugar Hollow Creek W, this dam plays a crucial role in water resource management in Jersey County, Illinois. With a spillway width of 15 feet and a maximum discharge capacity of 133 cubic feet per second, John Surgeon Pond Dam helps control water flow and mitigate flood risks in the area. Despite its undetermined hazard potential and limited condition assessment data, the dam remains operational and subject to periodic inspections by state authorities.
Water enthusiasts and climate advocates can appreciate the significance of John Surgeon Pond Dam as a key infrastructure supporting the local ecosystem. Its primary purpose extends beyond flood control to include recreational opportunities for the surrounding community. As climate change continues to impact water resources, the presence of well-maintained dams like John Surgeon Pond serves as a crucial asset in ensuring water security and resilience in the face of evolving environmental challenges.

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 John Surgeon Pond Dam
Where does the data for John Surgeon Pond 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 Undetermined 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.
