Mississippi River Lock And Dam 16 dam
Mississippi River Lock And Dam 16
Mississippi River Lock and Dam 16, also known as Pool 16, is a federal-owned structure located in Muscatine, Iowa along the Mississippi River. Completed in 1937, this concrete dam serves the primary purpose of navigation on the river, with a hydraulic height of 9 feet and a structural height of 34 feet. It features a multi-arch core design and spans 4400 feet in length, with a spillway width of 1315 feet to manage water levels during periods of high discharge.
Managed by the US Army Corps of Engineers, Lock and Dam 16 plays a crucial role in mitigating flood risks in the area. With a significant hazard potential, the dam is regularly inspected and monitored to ensure its structural integrity and readiness for emergency situations. The Corps actively engages with local emergency managers and the public to raise awareness and develop emergency action plans, emphasizing the importance of preparedness and response in case of a dam-related emergency. Additionally, ongoing maintenance and repairs are conducted to keep the dam functioning effectively and safely.
In the face of evolving climate conditions and potential severe weather events, the management measures implemented by the US Army Corps of Engineers for Lock and Dam 16 aim to address all types of flood risks associated with the structure. By prioritizing activities that reduce risks, maintaining communication with stakeholders, and updating emergency action plans, the Corps strives to ensure the resilience and reliability of the dam in the long term. As water releases and pressure management are key strategies for flood risk management, ongoing efforts are dedicated to safeguarding the surrounding community and the integrity of Lock and Dam 16.

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 16
Where does the data for Mississippi River Lock And Dam 16 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.
