Each winter, upwards of 60 bald eagles migrate south in search of food, and the Columbia River is a favorite winter vacation home. The U.S. Army Corps of Engineers (Corps) is eager to host its 12th annual Eagle Watch at the Dalles Dam Visitor Center, 10 a.m. to 3 p.m. on Fridays and Saturdays, January 21st, 22nd, 28th and 29th.
