With winter, bald eagles and other raptors have made their annual arrival to the area around The Dalles Lock and Dam.   Park ranger Amber Tilton explains the eagles return every winter as the Columbia River provides a good source of fish, and the area is secluded, quiet, and dark, leaving the birds undisturbed.  The dam’s Seufert Park is open daily from dawn to dusk, and The Dalles Lock and Dam Visitors Center is open from 9 a.m. to 3 p.m. on Saturdays and Sundays.  The annual Eagle Watch event will take place on Saturday, January 19.  Tilton notes operations at The Dalles Lock and Dam continue in spite of the partial federal government shutdown, as the Army Corps of Engineers is a part of the Defense Department.
