Lost Nation Country Club Lake Dam dam
Lost Nation Country Club Lake Dam
Lost Nation Country Club Lake Dam, located in Grand Detour, Illinois, is a privately owned earth dam built in 1975 primarily for recreational purposes. The dam stands at a height of 30 feet and spans a length of 570 feet, with a storage capacity of 1013 acre-feet. Situated on Clear Creek, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular state inspections to ensure its safety and compliance with regulations.
With a low hazard potential and moderate risk assessment, Lost Nation Country Club Lake Dam is considered to be in relatively good condition, though specific details on its current state are not available. The dam features an uncontrolled spillway and outlet gates, and is not associated with any other structures. While it does not have an Emergency Action Plan prepared, the dam is subject to regular inspections every five years to monitor its integrity and address any potential risks.
For water resource and climate enthusiasts, Lost Nation Country Club Lake Dam serves as a notable example of a privately owned recreational dam in Illinois. Its construction and design details, as well as its regulatory oversight by the state authorities, offer valuable insights into the management of dams for leisure purposes. Despite its low hazard potential, ongoing inspections and risk assessments ensure the safety of this structure and its surrounding area along Clear Creek.

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 Lost Nation Country Club Lake Dam
Where does the data for Lost Nation Country Club 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.
