Significance: Willamette Falls Locks permitted river traffic to avoid the navigational hazards of Willamette Falls and Clackamas Rapids (as well as the expense of portage) and allowed for successful competition with railroad transportation so as to lower freight rates. Such competition was particularly critical to the burgeoning agricultural center lying to the south in the Willamette Valley.
