Joliet Junior College Lake Dam dam
Joliet Junior College Lake Dam
Located in Joliet, Illinois, the Joliet Junior College Lake Dam stands as a vital structure along the TRIB ROCK RUN CREEK, serving its primary purpose of recreation since its completion in 1980. Designed by BELING ENGINEERING CONSULTANTS, this earth dam boasts a height of 11 feet and a length of 345 feet, providing a serene 8-acre surface area for water enthusiasts to enjoy. With a maximum storage capacity of 59 acre-feet and a drainage area of 0.7 square miles, this dam plays a crucial role in managing water resources in the region.
Managed by the local government and regulated by the Illinois Department of Natural Resources, the Joliet Junior College Lake Dam is subject to regular inspections to ensure its structural integrity and safety. With a spillway width of 28 feet and a significant hazard potential, this dam is equipped to handle a maximum discharge of 952 cubic feet per second, safeguarding the surrounding area from potential flooding risks. Despite its moderate risk assessment level, the dam's emergency action plan and risk management measures remain undisclosed, leaving room for further evaluation and enhancement of its safety protocols.
For water resource and climate enthusiasts, the Joliet Junior College Lake Dam presents a fascinating case study in dam management and recreational water usage. As a key feature in the local landscape, this dam serves not only as a source of leisure and relaxation but also as a critical component of the region's water infrastructure. With its unique design and strategic location, the Joliet Junior College Lake Dam offers a glimpse into the intersection of human engineering and natural resource management, highlighting the importance of sustainable water practices in today's changing climate.

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 Joliet Junior College Lake Dam
Where does the data for Joliet Junior College 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 Significant 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.
