Castle Ridge Lake Dam dam
Castle Ridge Lake Dam
Castle Ridge Lake Dam, located in Madison County, Illinois, stands as a testament to the innovative engineering expertise of HURST-ROSCHE ENGINEERS, INC. This private dam, completed in 2002, serves primarily for recreational purposes, offering a serene oasis for water resource and climate enthusiasts alike. With a height of 42 feet and a length of 875 feet, this earth-core dam boasts a storage capacity of 209 acre-feet and a surface area of 14 acres, making it a vital water management infrastructure in the region.
The dam, situated on TRIB MILL CREEK, falls under the regulatory jurisdiction of the Illinois Department of Natural Resources (IDNR) and undergoes regular inspections to ensure its structural integrity. Despite its high hazard potential, the dam's risk assessment remains at a moderate level, indicating proactive risk management measures in place. With an uncontrolled spillway and no outlet gates, Castle Ridge Lake Dam poses both challenges and opportunities for maintaining its operational efficiency and safety standards amidst changing climate conditions.
As climate change continues to impact water resources, Castle Ridge Lake Dam stands as a critical structure in the St. Louis District, providing both recreational benefits and water management functions. With its strategic location in Lebanon, Illinois, and a strong foundation on soil, this dam serves as a vital asset for the community while highlighting the importance of sustainable water resource management in the face of evolving climate challenges.

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 Castle Ridge Lake Dam
Where does the data for Castle Ridge 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.
