Orland Park Basin Dam dam
Orland Park Basin Dam
Orland Park Basin Dam, also known as Orland Park Detention Lake, is a crucial structure in Cook County, Illinois, designed by GUILLOU & ASSOCIATES to reduce flood risks along Marley Creek. Completed in 1992, this earth dam stands at 7 feet tall and spans 3600 feet, providing a storage capacity of 220 acre-feet. While its primary purpose is flood risk reduction, the dam has a low hazard potential and is regulated by the Illinois Department of Natural Resources.
Located in Orland Park, this dam plays a vital role in managing water flow and protecting surrounding areas from potential flooding events. With a maximum discharge capacity of 476 cubic feet per second and an uncontrolled spillway width of 62 feet, the Orland Park Basin Dam is equipped to handle moderate risk levels. Regular inspections are conducted, with the last inspection taking place in August 2017, ensuring the structure's integrity and functionality.
For water resource and climate enthusiasts, the Orland Park Basin Dam serves as a noteworthy example of infrastructure designed to mitigate flood risks and protect communities in Illinois. Its strategic location, design features, and regulatory oversight by the state highlight the importance of effective water management practices in the face of changing climate conditions. The dam's role in safeguarding against inundation events underscores the critical need for resilient infrastructure in the preservation of water resources and the prevention of environmental hazards.

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 Orland Park Basin Dam
Where does the data for Orland Park Basin 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.
