Grand Oaks Lake Dam dam
Grand Oaks Lake Dam
Grand Oaks Lake Dam, located in North Pekin, Illinois, is a privately owned structure built in 1978 for recreational purposes. Standing at a height of 22 feet and spanning 285 feet in length, this earth dam holds a maximum storage capacity of 52 acre-feet and covers a surface area of 5 acres. Situated on Trib Lick Creek, the dam is regulated by the Illinois Department of Natural Resources and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite its uncontrolled spillway type and significant hazard potential, Grand Oaks Lake Dam has a moderate risk rating of 3. The dam's primary purpose is to provide recreational opportunities for the community, offering a serene oasis for water resource and climate enthusiasts to enjoy. While the condition assessment is currently not available, the dam's emergency action plan was last revised in 2005, emphasizing the importance of preparedness and risk management measures in case of any unforeseen events.
Managed by private owners, Grand Oaks Lake Dam serves as a vital water resource in Tazewell County, Illinois, supporting a drainage area of 0.5 square miles. With its picturesque location and historical significance, the dam stands as a testament to the intersection of human engineering and natural beauty, inviting visitors to appreciate the delicate balance between water conservation and recreational enjoyment in this tranquil setting.
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.
Plan around the weather

About Grand Oaks Lake Dam
Where does the data for Grand Oaks 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.
