Holiday Lake Dam dam
Holiday Lake Dam
Holiday Lake Dam, also known as Lake Holiday, is a privately owned structure located in LaSalle County, Illinois. Built in 1965 by Dodson, Kinney & Lindblom, the dam serves primarily for recreational purposes, providing a serene escape for water resource and climate enthusiasts. Situated on Somonauk Creek, the dam boasts a height of 41 feet and a length of 1110 feet, with a storage capacity of 10,159 acre-feet and a surface area of 295 acres.
Managed by the Illinois Department of Natural Resources, the Holiday Lake Dam is regulated, inspected, and enforced to ensure public safety in the event of emergencies. With a high hazard potential, the dam is equipped with an uncontrolled spillway and outlet gates, highlighting its importance in flood control and water management. Despite its moderate risk assessment, the dam has not undergone a recent condition assessment, emphasizing the need for continued monitoring and maintenance to uphold its structural integrity.
As a focal point for outdoor recreation and water conservation efforts, Holiday Lake Dam stands as a vital resource in the Sheridan community. Its picturesque surroundings and vital role in water management make it a must-visit destination for those passionate about water resources and climate preservation.

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 Holiday Lake Dam
Where does the data for Holiday 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 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.
