Keeven Lake Dam dam
Keeven Lake Dam
Located in Columbia, Illinois, Keeven Lake Dam is a private structure designed by Suzanne Goldak for irrigation purposes. Completed in 1998, this Earth dam stands at a height of 25 feet with a length of 300 feet, providing a storage capacity of 140 acre-feet. The dam is situated on Prairie Du Long Creek and is regulated by the Illinois Department of Natural Resources.
With a spillway width of 56 feet and a maximum discharge of 567.5 cubic feet per second, Keeven Lake Dam has a significant hazard potential and is inspected every three years. While the condition assessment is not available, the dam is considered to have a moderate risk level (3) based on risk assessment. The dam's primary purpose is irrigation, serving the local agricultural community by providing water storage for irrigation needs.
For water resource and climate enthusiasts, Keeven Lake Dam offers a glimpse into the infrastructure supporting agricultural activities in Monroe County, Illinois. The dam's location, design characteristics, and regulatory oversight present a unique case study in water resource management and the intersection of human activity with natural systems. As efforts continue to ensure the safety and efficiency of the dam, its role in sustaining local agriculture underscores the importance of responsible water use in the face of changing climate conditions.

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 Keeven Lake Dam
Where does the data for Keeven 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.
