Corps Begins 80th Mississippi River Revetment Season
The Army Corps of Engineers Vicksburg District launched its annual riverbank protection work as the Mat Sinking Unit fleet began operations on November 4.
Updated on Nov. 5, 2026 in Safety
The U.S. Army Corps of Engineers Vicksburg District began its 80th annual Mississippi River revetment season, with the Mat Sinking Unit fleet launching operations on November 4, 2025. Crews place articulated concrete mats along the river to reduce erosion and protect levees.
Why it matters
Revetment reduces riverbank erosion, protects levees and flood control structures, and maintains a safe navigation channel for the river. The work supports the broader Mississippi River and Tributaries flood control system that Mississippi communities rely on.
The Mississippi River and Tributaries system has prevented an estimated $2.7 trillion in flood damages since 1928, with more than $124 returned for every federal dollar invested. The Mat Sinking Unit covers approximately 950 miles of river, though the stub does not report acreage or mileage treated this season.

The Corps district responsible for launching and directing the Mississippi River revetment season, which oversees flood control and navigation work on the river.
The details
Specialized crews place articulated concrete mats, known as revetment, along the Mississippi River to protect riverbanks and levees. The Memphis, Vicksburg and New Orleans districts coordinate the work, and crews took part in the annual Blessing of the Fleet ceremony before the season began.

Seasonal Patterns
The 80th annual revetment season continues work tied to the Mississippi River and Tributaries flood control system that began preventing damages in 1928. The annual cycle of riverbank protection has sustained that system's record of returning more than $124 for every federal dollar invested.
Residents near the Mississippi River should be aware of ongoing revetment work and related navigation and levee activity during the season. Stay alert to official Corps notices about work affecting river access or nearby levees.
The takeaway
Protecting the Mississippi's banks and levees is ongoing annual work that keeps communities and navigation channels safe. Its long-term return on federal investment makes steady maintenance a practical priority for the region.
