Mississippi River Locks And Dam 15 dam
Mississippi River Locks And Dam 15
Mississippi River Locks and Dam 15, also known as Pool 15, is a federal-owned structure located in Scott County, Iowa. Completed in 1934, this concrete gravity dam serves primarily for navigation purposes on the Mississippi River. With a hydraulic height of 16 feet and a structural height of 41 feet, the dam spans 1606 feet in length and has a storage capacity of 30,000 acre-feet.
The dam features a controlled spillway with a width of 1203 feet and includes two locks, each measuring 600 feet in length and 110 feet in width. Despite its significant hazard potential, the dam is equipped with an emergency action plan, regularly updated by the US Army Corps of Engineers, to manage flood risks associated with the structure. Through continuous monitoring, maintenance, and collaboration with local emergency managers, the USACE works diligently to ensure the structural integrity of the dam and mitigate potential risks to surrounding areas.
As a critical infrastructure on the Mississippi River, Locks and Dam 15 plays a vital role in regulating water levels and facilitating navigation along the waterway. With a comprehensive risk management approach in place, including regular inspections, emergency preparedness, and public outreach, the dam serves as a testament to the importance of proactive measures in safeguarding water resources and addressing climate-related challenges 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 Mississippi River Locks And Dam 15
Where does the data for Mississippi River Locks And Dam 15 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.
