Canemah, built almost at the river's level, was wiped out by the flood of December 1861. Afterwards, the wharves and some buildings were reconstructed, and prosperity seemed certain. More steamboats were built and a portage railway was built along the east back to replace the lumbering ox carts. The People's Transportation Company was organized, and the company built an improved boat basin above the falls. A canal was cleared below the falls which lessened the portage distance. New steamboats were built above the falls to serve customers upriver. These included a second "Yamhill" (1860), &lt;a href="Unio%20%28sternwheeler%29"&gt;"Unio"/"Union"&lt;/a&gt; (1861), a second "Enterprise" (1863), "Reliance" (1865), "Active" (1865), "Fannie Patton" (1865), "Echo" (1865), "Albany" (1868), "Success", and "Dayton" (1868).
