In 1929 Congress authorized the construction of locks and dams on the Upper [[MISSISSIPPI RIVER]]. The purpose was to maintain a nine-foot deep ~~channel~~ enabling barges and other river craft to use the river through the season of open water. (1) In 1933 a survey indicated that a dam with locks could be constructed less than a mile above Specht's Ferry. (2) An Army Corps of Engineers report, however, found that the river bedrock was not suitable. A second survey indicated that Dubuque would be a good alternative. In addition, the project would provide jobs for many unemployed people. (3) In late 1933 a precise location for the construction was chosen upstream from the [[EAGLE POINT BRIDGE]].

	Work on the lock and dam, named for famed explorer [[PIKE, Zebulon Montgomery\|Zebulon Montgomery PIKE]], began in 1933 with the construction of the locks. Workers earned thirty-five to fifty cents per hour with skilled labor making $1.25. A cofferdam was first constructed around the site of the lock and the area was inside pumped dry for the workmen.

	Workers replaced mitre gates which control the water level in the lock on May 2, 2018. Cracks had been discovered during a routine inspection. These were considered temporary repairs. That work was in addition to the scheduled closings for mitre gate replacements on May 8th and 10th. (18) The cracks that appeared at the anchorage at Lock and Dam 11 caused an immediate emergency closure of the facility which stopped traffic up and down the Mississippi for twenty-four hours.

	[[Image:crash.jpeg\|left\|thumb\|250px\|Barges crash into the lock and dam on May 4, 2018]] On May 4, 2018 perhaps the greatest threat to the lock and dam occurred. In the afternoon, a group of twelve barges broke apart from the towboat and struck the dam. One of the barges went over the dam on Saturday morning while two others filled with corn and beans sank above the dam. Damage to the dam was not known four days later. The announcement was made that efforts to raise the sunken barges would not be made until the water level dropped.

	When the lock-and-dam structures at Dubuque, Bellevue and Guttenberg, Iowa were installed in the 1930s they were designed for a life expectancy of fifty-years. (21) Through careful maintenance, the U. S. Army Corps of Engineers have lengthened that time period. In 2018, however, there was no plan for replacement. In the latest annual reports, Corps officials state that maintenance needs have surpassed annual operations and maintenance budgets. New locks should be modernized by making them twice as long eliminating the need to split a tow allowing only some barges to be moved at a time--a process that could take ninety minutes.

	Making the situation dire was the ~~increase~~ use of the river to move commerce. In 2016 an estimated 18.9 million tons of commodities moved through Lock and Dam 11. That was the highest tonnage in Dubuque since 2002 and a 28% increase over 2017. Sixty percent of the total or 11.4 million tons was food and farm products. Among the reasons given was the expansion of the Panama Canal and sections of the Mississippi being dredged allowing larger ships to move further inland. River transportation continues to have a lead over other carriers. One 15-barge tow carries as much material as 240 rail cars or 1,050 semis. The tourism industry centering on the river depends upon the locks-and-dams as much as the tows. (23)		Making the situation dire was the increased use of the river to move commerce.

	In 1940 the J. T. McCarthy Company of Davenport entered the lowest bid of $136,239.70 for the construction of a 700-foot extension of the locks upstream. This guide wall was designed to cut down on the swift cross-currents above the dam which made locking of boats dangerous. Prior to construction of the wall, pilots had to enter the locks at an angle, then flank to align their tows with the lock. If not carried out properly, the maneuver could lead to a tow carried out of control and slamming into the dam. (11)		In 1940 the J. T.
