A downbound tow locks through Lock and Dam 1
Background Constrained funding has led to reduced operations and maintenance funding within the Corps Inland Marine Transportation System (IMTS). When coupled with deteriorating infrastructure and increasing costs of operation, it became clear that the level of service the Corps has been providing at some locks and dams is not sustainable. The three locks and dams in the Twin Cities: Upper St. Anthony Falls (USAF), Lower St. Anthony Falls (LSAF), and Lock and Dam 1 (LD1), are part of the Corps’ IMTS consisting of 12,000 miles of inland waterways and more than 200 locks and dams. The IMTS Board of Directors approved guidance in 2012 that established six levels of operational service for all IMTS locks. The criteria were based on the number of commercial and recreational lockages that passed through the locks on an annual basis.
Status At the start of the 2015 navigation season these 3 locks were open 19 hours per day/7 days per week. As required by the Water Resources Reform and Development Act 2014, USAF lock was closed to navigation on 10 June 2015. Upon closure of the USAF lock, LSAF and LD1 transitioned to one 10-hour shift per day for the remainder of 2015 navigation season.
