Department of the Army, Corps of Engineers August 5, 2019 – Federal Register Recent Federal Regulation Documents

The St. Paul District is proposing to reduce the hours of operation at Lock and Dam 1 from 10 hours per day, 7 days per week to 10 hours per day on weekends and holidays and 6 hours per day on Mondays and Fridays. Commercial lockages would be available by appointment only with 24 hours' notice Tuesday through Thursday during normal duty hours of 0700-1530. Proposed hours of operation are 1200- 1800 Fridays and Mondays, and 0800-1800 Saturdays, Sundays and holidays. Hours of operation at Lower St. Anthony Falls will not change. This change will help achieve the goal of providing consistent levels of operating service for all locks across the Inland Marine Transportation System (IMTS) with a consistent approach, optimizing Operations and Maintenance expenditures for these assets and extending the service life of navigation locks by optimizing usage. The navigation season on the Upper Mississippi normally begins in March and ends in December, but varies based on river conditions. Pool levels will not be affected by this change of operating hours.
