About this dam

Maple Brook Estates Dam

Maple Brook Estates Dam, located in Bolingbrook, Illinois, along Lily Cache Creek, is a privately owned concrete dam designed by CBBEL in 1997 for flood risk reduction. The dam stands at 7 feet tall and spans 63 feet in length, with a storage capacity of 97 acre-feet. While its hazard potential is considered low, the risk assessment categorizes it as moderate (3), indicating a level of caution and preparedness required for potential emergencies.

Managed by the Illinois Department of Natural Resources (IDNR), the dam undergoes regular state inspections and enforcement to ensure its structural integrity and compliance with regulations. With an uncontrolled spillway and no outlet gates, the dam primarily serves the purpose of flood risk reduction for the surrounding area. Congressman Bill Foster represents the district where Maple Brook Estates Dam is located, highlighting the importance of water resource management and climate resilience in the region.

Overall, Maple Brook Estates Dam plays a crucial role in mitigating flood risks in Will County, Illinois, contributing to the protection of nearby communities and infrastructure. As a key piece of infrastructure along Lily Cache Creek, the dam's construction, design, and maintenance showcase the collaboration between private ownership, state regulation, and environmental stewardship in safeguarding water resources and addressing climate challenges 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.

FAQ

About Maple Brook Estates Dam

Where does the data for Maple Brook Estates 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.
