Lock and Dam No. 22 is a lock and dam located near Saverton, Missouri, on the Upper Mississippi River around river mile 301.2. The movable portion of the dam is 1,224 feet (373.1 m) long and consists of three roller gates and ten tainter gates. A 1,600 feet (487.7 m) long submersible earthen dike extends to a flood control levee on the Illinois shore. The main lock is 110 feet (33.5 m) wide by 600 feet (182.9 m) long; there is also an incomplete auxiliary lock.[2] In 2004, the facility was listed in the National Register of Historic Places as Lock and Dam No. 22 Historic District, #04000182 covering 1,268 acres (5.1 km2), 1 building, 5 structures, 4 objects.
When the northern part of Mississippi freezes, near the first week of February, upwards of 20 bald eagles fly down to fish in the churning waters below Lock and Dam No. 22.
