This image of Lock and Dam Number 11 was taken from Eagle Point, looking east across the Mississippi River. The walls of the lock, visible in the foreground, appear to be almost complete. The roller and tainter gate walls further out in the Mississippi River, are in the beginning stages of construction. A crane and other construction equipment may be seen near the roller dam walls. A dredge is visible in the pool behind the dam. The number 1286-1 is written on a label that has been stuck to the lower left corner of the slide.
