As the U.S. Army Corps of Engineers releases its 20-year dredging plan for the Columbia River, tribes say they want more of a say in how the operation affects their fishing and cultural priorities. The Corps acknowledges that its ongoing work to maintain the 43-foot deep channel is detrimental to salmon and other species. The Trump administration, which cancelled a historic river co-management agreement with tribes, now wants to facilitate larger, more powerful shipping barges on the river that already transports more than 26 million tons of grain a year. But the Confederated Tribes of Grand Ronde, the Cowlitz Tribe, and others say the waterway is more than just a highway for agricultural exports. They want their voices reflected in future river dredging decisions.
