Mississippi River Lock And Dam 10 dam
Mississippi River Lock And Dam 10
Mississippi River Lock and Dam 10, located in Guttenberg, Iowa, is a vital water resource structure managed by the US Army Corps of Engineers. Completed in 1937, this concrete dam stands at 20 feet high with a hydraulic height of 33 feet and a structural height of 43 feet. The dam serves the primary purpose of navigation on the Mississippi River, with recreational activities also supported in the area.
Lock & Dam 10 features a controlled spillway that regulates the water level for navigation purposes, with a maximum discharge capacity of 308,000 cubic feet per second. Despite being classified as a significant hazard potential structure, the risk assessment conducted in 2015 deemed it a low-risk dam due to ongoing risk management measures implemented by USACE. Regular maintenance and repairs are conducted to ensure the dam's functionality and to address potential risks such as aging infrastructure and navigation accidents.
USACE remains committed to reducing risks associated with Lock & Dam 10, engaging with the public to raise awareness and coordinating with emergency managers during flood events. With a focus on safety and effective risk management, this dam continues to play a crucial role in maintaining river traffic while safeguarding the surrounding environment and communities.

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 Mississippi River Lock And Dam 10
Where does the data for Mississippi River Lock And Dam 10 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.
