Next, at editor Jaime Gross's suggestion, I headed north to Ballard and to the Hiram M. Chittenden Locks, more often referred to as simply the Ballard Locks. Connected to the Carl S. English, Jr. Botanical Gardens, the area offers quite a lot to take in. I was fortunate enough to catch two fishing boats pass through the locks—which mitigate the 20-22 foot difference between Lake Washington and Lake Union and prevent the mix of Puget Sound's saltwater with the lakes' freshwater. The most popular attraction here, however, is the fish ladder, which allows salmon to make their migratory runs and features five viewing windows, where I spotted a couple handfuls of nearly four-foot-long fish.
