LOWER SNAKE RIVER, Wash. – If your upcoming Washington’s Birthday weekend plans include a road trip to visit family and friends on the opposite side of the lower Snake River, you may want to keep in mind that U.S. Army Corps of Engineers dams on the river in Washington are closed to cross-dam public vehicle traffic on federally recognized holidays, unless otherwise announced. Lower Granite Lock and Dam, near Pomeroy, Wash., will be open for public vehicle crossings from 7 a.m. to 5 p.m. on the Monday, Feb. 19, holiday. However, Walla Walla District operations officials want to remind the public of the Washington’s Birthday holiday closure affecting two of three dams that normally allow public vehicle crossings – Little Goose, near Starbuck, Wash.; and Lower Monumental, near Kahlotus, Wash. Little Goose and Lower Monumental are normally open Monday through Thursday, but will be closed for the holiday.
