CLARKSTON, WA – The U.S. Army Corps of Engineers' Walla Walla District will begin dredging two sections of the lower Snake River navigation channel in the Lewis-Clark Valley and near Pasco beginning next month. The dredging will remove accumulated sediment from the federal navigation channel near the confluence of the Snake and Clearwater Rivers in Clarkston and below the Ice Harbor Lock and Dam navigation lock near Pasco. All dredged sediment will be disposed of at an in-water location near Bishop Bar (north shore) located at River Mile 118 on the lower Snake River in Washington.
