Spring Brook Gabion Dam dam
Spring Brook Gabion Dam
Located in Normantown, Illinois, the Spring Brook Gabion Dam, also known as the Spring Brook Retention Basin, was completed in 1984 by LINDLEY & SONS. This local government-owned structure serves as a crucial flood risk reduction measure along the Spring Brook River. The dam stands at a height of 9 feet and spans 400 feet in length, with a storage capacity of 89 acre-feet.
With its primary purpose being flood risk reduction, the Spring Brook Gabion Dam also offers recreational opportunities for the community. Despite its low hazard potential, the dam has a moderate risk assessment rating. The dam is state-regulated by the Illinois Department of Natural Resources, ensuring regular inspections and enforcement of safety measures. The structure features an uncontrolled spillway with a width of 8 feet, and although no outlet gates are present, the dam effectively manages a maximum discharge of 1047 cubic feet per second.
Water resource and climate enthusiasts will appreciate the strategic design and functionality of the Spring Brook Gabion Dam in mitigating flood risks along the Spring Brook River. As a vital infrastructure in DuPage County, Illinois, this dam showcases the importance of proactive measures in water management and disaster prevention. The collaborative efforts of local government agencies and regulatory bodies ensure the safety and efficiency of this essential structure, contributing to the overall resilience of the surrounding community.

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 Spring Brook Gabion Dam
Where does the data for Spring Brook Gabion 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.
