David B. Williams shares insights from his newest book about the Ballard locks. Few engineering projects have shaped Seattle as much as the construction of the Hiram M. Chittenden Locks and Ship Canal. Nor do many have as many false starts, political shenanigans, and chaotic history. In this talk based on his co-authored history of the canal and locks, Seattle’s Locks and Ship Canal: A History and Guide (published in Spring 2026), he shares the far-reaching social, economic, and environmental impacts of the canal’s construction and operation. David will have books for sale.
