Mississippi River Lock 19 live webcam
Keokuk is home to U.S. Lock #19. When completed in 1913, it was the largest electricity generating plant in the world. The locks are 1200 feet long and 110 feet wide, and large enough to handle a full-length fleet of barges. Major commodities moved include grain, aggregate, petroleum, coal and chemicals. The present lock was put into operation in 1957 at a cost of $13.5 million dollars. It is owned and operated by the U.S. Army Corps of Engineers. The Power House and spillways are owned and operated by AmerenUE, a privately owned utility company. The lock normally operates from early March thru early December, and is open 24/7 seven days a week. With a 38 feet (11.6 m) difference between the normal pool above and below, the lock has the highest "step" in the stairway of the Rock Island District locks.
