Zarges Pond Dam dam
Zarges Pond Dam
Zarges Pond Dam, located in Wood River, Illinois, is a privately owned structure designed by the USDA NRCS and regulated by the Illinois Department of Natural Resources. Completed in 1978, this earth dam stands at a height of 30 feet and has a length of 217 feet, creating a reservoir with a storage capacity of 48 acre-feet. The dam serves multiple purposes, including recreation, and is situated on the TR-Wood River Creek NW.
With a low hazard potential and a moderate risk assessment rating, Zarges Pond Dam is a crucial component of water resource management in Macoupin County. Despite its relatively small surface area of 3 acres and drainage area of 0.16 square miles, the dam plays a significant role in controlling water flow and mitigating flood risks in the region. The dam's uncontrolled spillway and outlet gates provide essential functionality for managing water levels and maintaining safety.
Although the condition assessment of Zarges Pond Dam is currently listed as "Not Available," regular inspections by the state regulatory agency ensure that the structure meets safety standards. With its strategic location and important role in water resource management, Zarges Pond Dam stands as a testament to the collaborative efforts of private owners, government agencies, and designers in safeguarding the local community against potential risks and enhancing recreational opportunities in the area.

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 Zarges Pond Dam
Where does the data for Zarges 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 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.
