The crew of Launch 23, one of two hydrographic survey boats used by the St. Paul District to support dredging operations, conducts a post-dredge survey near Read’s Landing, Minn., on May 31. The survey – to verify that the 9-foot navigation channel is maintained – took place shortly after the Dredge Goetz removed an estimated 60,000 cubic yards (the survey will verify the exact amount) of dredged material from the navigation channel during its one-week mission here. The dredge – one of five dredging operations working on the Upper Mississippi River from St. Paul to Guttenberg, Iowa – will next move a few miles downstream as the district works to keep the navigation channel open for commercial tows, a high priority task given the amount of sediment moved into the channel due to spring flooding.
