Barwell Lake Dam dam
Barwell Lake Dam
Barwell Lake Dam, located in Mackinaw, Illinois, was completed in 1956 and serves as a key recreational resource in the area. Owned privately, this earth dam stands at a height of 31 feet and boasts a length of 275 feet, providing a storage capacity of 61 acre-feet. While primarily used for recreation, the dam is also state-regulated and inspected regularly by the Illinois Department of Natural Resources to ensure its safety and compliance with regulations.
Situated on Trib Vincent Run, a tributary in Woodford County, Barwell Lake Dam's hazard potential is deemed low with a moderate risk assessment score of 3. Despite being uncontrolled, the spillway and outlet gates function efficiently to manage water flow. The dam's condition assessment is currently not available, but it meets all necessary guidelines for emergency action preparedness. The surrounding area enjoys the benefits of this dam for various recreational activities, making it a valuable asset to both locals and visitors alike.
With its tranquil setting and scenic beauty, Barwell Lake Dam offers a serene escape for water resource and climate enthusiasts. Its strategic location and low hazard potential make it an ideal destination for outdoor activities and relaxation. As a well-maintained structure with a history dating back to the mid-20th century, this dam continues to play a vital role in the community, ensuring a safe and enjoyable environment for all who appreciate the wonders of nature and water resources.

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 Barwell Lake Dam
Where does the data for Barwell 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 Low 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.
