Pratt Pond Dam dam
Pratt Pond Dam
Pratt Pond Dam, located in Bryant, 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 26 feet and spans 240 feet in length. Its primary purpose is to serve as a Fish and Wildlife Pond, offering recreational opportunities while also supporting local flora and fauna.
With a storage capacity of 32 acre-feet, Pratt Pond Dam is part of the TR-Big Creek watershed and covers a surface area of 3 acres. The dam features an uncontrolled spillway with a width of 34 feet, and its hazard potential is classified as low. Despite its moderate risk assessment rating, the dam's condition assessment is currently listed as "Not Available" as of the last inspection in July 2015.
For water resource and climate enthusiasts, Pratt Pond Dam presents an intriguing case study in private dam ownership and regulatory oversight. Its location within the Kansas City District and proximity to the Big Creek river system make it a valuable asset for wildlife preservation and outdoor recreation in Fulton County, Illinois. As efforts continue to monitor and maintain this structure, its role in supporting the local ecosystem and community resilience remains essential in the face of changing environmental conditions.

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 Pratt Pond Dam
Where does the data for Pratt 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.
