Streator Vermilion River Dam dam
Streator Vermilion River Dam
The Streator Vermilion River Dam, located in Livingston County, Illinois, was completed in 1925 and serves as a crucial water supply structure along the Vermilion River. This private dam stands at a height of 14 feet with a length of 220 feet, providing a storage capacity of 1330 acre-feet. The dam primarily functions as a gravity structure with a buttress core type, designed for water supply purposes.
Managed by the Illinois Department of Natural Resources (IDNR), the Streator Vermilion River Dam is subject to state regulation, inspection, and enforcement to ensure its safe operation. With a significant hazard potential and moderate risk assessment rating, the dam's emergency action plan status and risk management measures are currently not available. The dam's spillway, classified as uncontrolled, features a width of 200 feet, highlighting its importance in managing water flow and preventing potential flooding events in the area.
For water resource and climate enthusiasts, the Streator Vermilion River Dam presents a fascinating example of early 20th-century engineering for water supply infrastructure. As a vital component of the local water management system, this gravity dam underscores the importance of ongoing monitoring and maintenance to mitigate risks and ensure the safety and reliability of water resources in the region.

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 Streator Vermilion River Dam
Where does the data for Streator Vermilion River 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.
