Minneapolis in Ramsey County, Minnesota — The American Midwest (Upper Plains)
The Lock and Dam No. 1 Story
Development began when a group of Minneapolis businessmen led by a territorial judge formed the Mississippi River Improvement and Manufacturing Company for the purpose of obtaining permission to construct a lock and dam below St. Anthony Falls, on Meeker Island. Legislation was passed for this purpose in 1857.
The project was surrounded by controversy for the next 30 years with opinions being divided over its future implications. When it appeared that the company was unable to settle internal strife, the project was turned over to the Corps of Engineers. Meeker Island Dam, the final official Lock & Dam No. 2, a couple of miles upstream from here, became operational in May, 1907.
By this time, authorization had already been received from Congress (in 1899) to construct Lock and Dam No. 1 which was to eventually submerge the recently completed Lock and Dam No. 2 at Meeker Island.
On July 3, 1917, Lock and Dam No. 1, with hydro-electric capability of 15,200 horsepower, was opened for navigation. Six years after completion, a lease was negotiated with the Ford Motor Corporation for utilization of the dam's power capabilities.
Between 1917 and 1925, the upper pool was used primarily by pleasure craft; the main reason being the lack of adequate terminals and turning basins.
All barge traffic was halted in August 1929 when the lower lock gate failed. To ensure against future interruptions and in anticipation of a 9-foot channel between Minneapolis and St. Louis, the decision was made to build twin lock chambers. The first lock –– the riverward lock –– was completed in 1930 and the second –– the landward lock –– was placed into operation in 1932.
Lock and Dam No. 1 continued to serve the needs of people using the river for navigation along with supplying the capability for hydro-electric power. As the years passed the need arose for major rehabilitation work to be done on the

Flooding in 1914 and 1916 caused work delays and damage to the high dam structure.
Work on the High Dam nears completion; note the collardam surrounding the work area to prevent the river from flowing through.
Failure of the lower gates along with anticipation of a 9-foot channel resulted in the building of the twin lock chambers.
Excavation for the center lock wall and the new landward lock chambers began in 1929.

Work on Lock & Dam No. 1 was completed in 1917 while construction continued on the hydroelectric plant on the right bank of the river.
The increase from a 3 ft. to a 6 ft. channel required lowering the floor of the lock chamber; photo is approximately 1911.
