The Willamette River flows northwards down the Willamette Valley until it meets the Columbia River at a point 101 miles from the Pacific Ocean, in the U.S. state of Oregon. Route and early operations In the natural condition of the river, Portland was the farthest point on the river where the water was deep enough to allow ocean-going ships. Rapids further upstream at Clackamas were a hazard to navigation, and all river traffic had to portage around Willamette Falls, where Oregon City had been established as the first major town inland from Astoria. The first steamboat built and launched on the Willamette was Lot Whitcomb, launched at Milwaukie, Oregon, in 1850. Lot Whitcomb was long, had beam, of draft, and 600 gross tons. Her engines were designed by Jacob Kamm, built in the eastern United States, then shipped in pieces to Oregon. Her first captain was John C. Ainsworth, and her top speed was . Lot Whitcomb was able to run upriver from Astoria to Oregon City in ten hours, compared to the Columbia'''s two days. She served on the lower river routes until 1854, when she was transferred to the Sacramento River in California, and renamed the Annie Abernathy. The side-wheeler Multnomah made her first run in August 1851, above Willamette Falls. She had been built in New Jersey, taken apart into numbered pieces, shipped to Oregon, and reassembled at Canemah, just above Willamette Falls. She operated above the falls for a little less than a year, but her deep draft barred her from reaching points on the upper Willamette, so she was returned to the lower river in May 1852, where for the time she had a reputation as a fast boat, making for example the run from Portland to Vancouver, Washington in one hour and twenty minutes. Another sidewheeler on the Willamette River at this time was the Mississippi-style Wallamet, which did not prosper, and was sold to California interests. In 1853, the side-wheeler Belle of Oregon City, an iron-hulled boat built entirely in Oregon, was launched at Oregon City. Belle (as generally known) was notable because everything, including her machinery, was of iron that had been worked in Oregon at a foundry owned by Thomas V. Smith. Belle lasted until 1869, and was a good boat, but was not considered a substitute for the speed and comfort (as the standard was then) of the departed Lot
