Peoria Lock And Dam dam
Peoria Lock And Dam
Peoria Lock and Dam, located on the Illinois River in Tazewell, Illinois, plays a vital role in navigation, being a concrete structure completed in 1939 by the US Army Corps of Engineers. With a hydraulic height of 11 feet and a structural height of 23 feet, it facilitates river traffic through its single lock with dimensions of 600 feet in length and 110 feet in width. The dam's primary purpose is navigation, and it helps manage water levels along the river.
Despite being classified as having a significant hazard potential, a recent risk assessment by the US Army Corps of Engineers found that Peoria Lock and Dam is well-designed, well-constructed, and well-maintained. The risk assessment revealed that a dam failure would primarily impact river navigation upstream of the dam, with minimal to no downstream property damages expected. To mitigate risks, USACE conducts regular inspections, maintenance, and monitoring of the dam, as well as coordinating emergency response plans with state and local agencies.
In addition to ongoing risk management measures, USACE is actively engaging with stakeholders and the public to increase awareness about the dam's safety and emergency response plans. With a robust communication strategy based on the latest risk assessment findings, Peoria Lock and Dam remains a critical infrastructure for water resource management and climate resilience 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 Peoria Lock And Dam
Where does the data for Peoria Lock And 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.
