Depere Lock And Dam dam
Depere Lock And Dam
Located on the Fox River in DePere, Wisconsin, the Depere Lock and Dam is a federal structure managed by the US Army Corps of Engineers to primarily reduce flood risks in the area. Completed in 1929, this concrete gravity dam spans 1,700 feet and stands at a structural height of 17 feet. With a maximum discharge capacity of 22,500 cubic feet per second, the dam also serves purposes such as fish and wildlife pond management, hydroelectric power generation, navigation, and recreation.
A recent risk assessment conducted in 2015 categorized the dam as having a low risk of causing loss of pool that could impact navigation and hydropower. The assessment identified three primary risk factors, including instability of the masonry wall, seepage through the embankment, and instability of the concrete dam. To manage these risks, the USACE, State, and hydropower company collaborate on regular inspections, maintenance, and emergency action plans. Proactive measures, such as replacing walkways and gates, repairing embankments, and transferring lock operations to the State, have increased the dam's reliability and long-term resilience.
Despite its significant hazard potential, the Depere Lock and Dam is closely monitored and maintained to ensure continuous operation and public safety. Through ongoing risk management measures, regular inspections, and coordinated emergency response plans, the dam continues to play a vital role in flood control, water management, and hydropower generation in the region. More information about the dam's water discharges and updates can be found on the USACE website to keep the public informed and engaged.

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 Depere Lock And Dam
Where does the data for Depere 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.
