Island Lake Dam dam
Island Lake Dam
Island Lake Dam, located in East Dundee, Illinois, is a privately owned structure with a primary purpose of serving as a Fish and Wildlife Pond. The dam, constructed in 1940, stands at a height of 35 feet and has a storage capacity of 40 acre-feet. It is regulated by the Illinois Department of Natural Resources (IDNR) and is situated on the tributary of the Fox River.
With a low hazard potential and moderate risk assessment rating, Island Lake Dam is a key component in managing water resources in Kane County, Illinois. While its condition assessment is currently unavailable, the dam undergoes inspections every five years to ensure its structural integrity. Although it has an uncontrolled spillway type, the dam plays a crucial role in supporting the local ecosystem and wildlife in the area.
For water resource and climate enthusiasts, Island Lake Dam offers a fascinating glimpse into the intersection of human infrastructure and environmental conservation efforts. As a vital element in the management of the Fox River tributary, this earth dam serves as a sanctuary for fish and wildlife while also mitigating flood risks in the region. Its historical significance, dating back to 1940, highlights the long-standing relationship between communities, water resources, and the natural environment in Kane County, Illinois.
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 Island Lake Dam
Where does the data for Island Lake 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.
