AAA Editor Notes

Fish Ladder, at the s. end of the dam at the Hiram M. Chittenden Locks, 3015 N.W. 54th St., is the only facility of its kind in the United States located at the confluence of salt and fresh water. This ingenious stairway, designed by Hiram Chittenden, consists of 21 weirs—each approximately a foot higher than the previous one—that enable migrating salmon to bypass the dam and locks. A viewing gallery features windows looking into the upper weirs, both above and below water level. Information panels and a wall mural illustrate the natural history of the four salmon species that utilize the ladder. Peak migration varies by species: sockeye (July), chinook (late August) and coho (late September). You may see tribal members fishing near the locks, which is permitted by treaties. Guided tours are available.
Hours: Viewing room daily 7 a.m.-8:45 p.m. One-hour guided tours of the fish ladder and Hiram M. Chittenden Locks depart the locks' visitor center daily at 1 and 3 (also Sat.-Sun. at 11), May-Sept.; Thurs.-Mon. at 2, Mar.-Apr. and Oct.-Nov. Allow 30 minutes minimum.
