Lock and Dam No. 19

In 2004, the facility was listed in the National Register of Historic Places as Lock and Dam No.

[2] The lock and dam, as well as the rest of the river, can be viewed from a distance on the Observation Deck of the Keokuk Rail Bridge.

[2] Construction began in 1910 and when completed in 1913 it was the largest capacity, single powerhouse electricity generating plant in the world.

The Power House and spillways are owned and operated by Ameren Missouri and has a 142 MW capacity.

[4] Today, Keokuk Energy Center remains the largest privately owned and operated dam on the Mississippi River.

2 and the upper St. Anthony Falls dam also produce electricity on the Mississippi River system.
