"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 134 MW capacity.[3] The powerhouse contains 15 generators, originally designed to produce 25 Hz instead of the 60 Hz alternating current used today. In the 1930s, Union Electric Company purchased this 25 Hz power for Streetcars in St. Louis, Missouri. This 25 Hz power configuration is still used for Amtrak's 25 Hz traction power system in the Northeast Corridor.[2] Lock and Dam No. 1, Lock and Dam No. 2 and the upper St. Anthony Falls dam also produce electricity." ~ Wikipedia


"In 1905 the U.S. Congress passed a bill granting the Keokuk and Hamilton Water Power Company the right to dam the river and construct a hydro-electric plant at the foot of the rapids and to build a new lock and dry dock to replace the canal which had become too small to handle the newer boats of the day. Construction on Lock and Dam No. 19 was started in 1910 and completed in 1913 with the cost being borne by the power company. The Keokuk Power House was the largest capacity, single powerhouse electricity generating plant in the world. The power house provided electricity for Keokuk and cities as far away as St. Louis. The power house also attracted a lot of industry to the Keokuk area.

"In 1957, the lock was replaced and upgraded to measure 1,200 feet by 110 feet at a cost of 13.5 million dollars. The lock and dam obliterated the Des Moines Rapids and created Lake Cooper, named after Hugh L. Cooper, the designer of the Keokuk Dam. Lake Cooper is the largest pool in the series of dams with 240 miles of shoreline. With a 38 feet (11.6 m) difference between the normal pool above and below the dam, the lock has the highest "step" in the stairway of the Rock Island District locks and dams. Lock and Dam #19 is owned and operated by the U.S. Army Corps of Engineers. The power house is owned and operated by AmerenUE, a privately owned utility company. The facility was listed in the National Register of Historic Places in 2004." ~ The Great River Road
