Hadley Creek Ws Str 1-7 dam
Hadley Creek Ws Str 1-7
Hadley Creek WS Str 1-7 is a privately owned earth dam located in Adams County, Illinois, near the city of Kinderhook. Built in 1958 by the USDA NRCS, this dam serves primarily for flood risk reduction on the Tr-Hadley Creek N Fork. With a dam height of 25 feet and a length of 370 feet, it has a storage capacity of 29 acre-feet and can handle a maximum discharge of 240 cubic feet per second.
Despite its age, Hadley Creek WS Str 1-7 is classified as having a low hazard potential and a moderate risk level. The dam features an uncontrolled spillway and outlet gates, with no associated locks. While the condition assessment is currently listed as "Not Available," the dam is inspected every 5 years by the Natural Resources Conservation Service. The surrounding area has a drainage area of 0.11 square miles and a surface area of 2 acres, making it a vital asset for managing the water resources in the region.
Water resource and climate enthusiasts will appreciate the role that Hadley Creek WS Str 1-7 plays in mitigating flood risks and protecting the local community. As a key infrastructure for flood risk reduction, this dam serves as a testament to the importance of proper water management in safeguarding against natural disasters. With its strategic location and design, Hadley Creek WS Str 1-7 stands as a vital component in the system of water resource infrastructure in Illinois, showcasing the ongoing efforts to ensure the resilience of our water resources in the face of changing climate conditions.
Dam data reference
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 Hadley Creek Ws Str 1-7
Where does the data for Hadley Creek Ws Str 1-7 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.
