Sky Harbor Detention Area A Dam dam
Sky Harbor Detention Area A Dam
Sky Harbor Detention Area A Dam, located in Will County, Illinois, was completed in 2008 by MANHARD CONSULTING LTD as a private flood risk reduction structure on Jackson Creek. This earth dam stands at 7 feet tall and spans 850 feet in length, with a storage capacity of 28 acre-feet. The dam features a controlled spillway with a width of 161 feet, designed to manage high hazard potential during extreme weather events.
Managed by the Illinois Department of Natural Resources, Sky Harbor Detention Area A Dam is subject to regular inspections to ensure its structural integrity and functionality. With a very high risk assessment rating, emergency action plans are crucial for this dam, although specific details on the condition assessment and risk management measures are not currently available. The dam plays a critical role in mitigating flood risks in the area, providing essential protection for the surrounding community of New Lenox.
As a key component in the flood risk reduction strategy for the region, Sky Harbor Detention Area A Dam serves as a vital infrastructure asset in safeguarding against potential inundation and ensuring the safety of residents in Will County. Its strategic location and design features make it a crucial element in the overall water resource management system, highlighting the importance of proactive maintenance and emergency preparedness to address the high hazard potential associated with this essential structure.
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 Sky Harbor Detention Area A Dam
Where does the data for Sky Harbor Detention Area A 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 High 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.
