The U.S. Coast Guard is planning to discontinue the seasonal Sound Signal audio navigation aids at Umpqua River South Jetty Sound Signal and Yaquina Bay, both in Oregon, at the end of the 2024 spring installation, the agency announced Feb. 7.

The Coast Guard is seeking public feedback on the new changes and on the performance and operation of navigation aids. Meanwhile, U.S. Coast Guard Sector Columbia River is expected to continue receiving reports of any discrepancies to this and other navigation aids, the agency said.

“The U.S. Coast Guard values the input of the maritime community and remains dedicated to ensuring the safety and efficiency of waterborne transportation,” according to the Guard. “The decision to discontinue these sound signals aligns with ongoing efforts to modernize and optimize navigational systems.”
