Lock and Dam 2 Rehabilitative Work




There is major work happening at Lock and Dam 2 in Hastings.


The U.S. Army Corps of Engineers, St. Paul District, performs rehabilitative work on each of the district’s 13 locks and dams on the Upper Mississippi River every 15-20 years.


This year, it was time for Lock and Dam 2, to be dewatered for the first time since 2007.


The $3.5 million project includes inspection and repair of the concrete walls, the miter gates, the bubbler system and renovation of the weepholes, holes in the lock chamber that helps relieve the water pressure on the concrete floor.


This is the first dewatering that has been done with the new miter gates, which were replaced at Lock 2 in 2021.


The Corps of Engineers team can ensure proper fitting of the gates with the lock chamber during the dewatering and make adjustments so the gates operate smoothly.
