''Pomona'' was a steamboat which operated on the Willamette, Columbia and Cowlitz rivers from 1898 to 1940. ''Pomona'' was specially designed to operate in low water conditions such as typically prevailed in the summer months in Oregon. ''Pomona'' was one of the few steamers that could regularly navigate to Corvallis, Oregon which was the practical head of navigation on the Willamette. In 1926, ''Pomona'' was substantially rebuilt, and served afterwards as a towboat. In 1940, ''Pomona'' was converted into an unpowered floating storehouse. ==Design, construction and dimensions== ''Pomona'' was built for the Oregon City Transportation Company ("O.C.T.C."), which had been organized by the Graham family in 1889.〔 O.C.T.C. owned two other boats at the time, the ''Ramona'' and the ''Altona''. The ''Pomona'' was larger than both.〔 ''Pomona'' was built especially for the summer season on the Willamette River, when the water would be at its lowest.〔〔 ''Pomona'' drew only and was said to have been "an ideal boat for the low water season."〔 The boat was intended to carry passengers and handle the large freight business of the O.C.T.C.〔 ''Pomona'' was built by the Portland Shipbuilding Company at its yard at the foot of Meade Street.〔 According to a contemporaneous report, the steamer was 130 feet long 〔 ''Pomona'' had a beam of 26 feet and a depth of hold of 4.5 feet.〔 Passenger accommodations consisted of a day cabin and five staterooms.〔 According to the 1899 official steamboat registry, ''Pomona'' was long, with a beam of and depth of hold of . Typical vessel dimensions given in sources did not include the deck extension over the stern on which the sternwheel was mounted, nor did they measure the beam (width) of the vessel over the often wide overhanging heavy timbers, called "guards" that were installed along the top of the hull to protect it from damage. The official steamboat registry number was 150782.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Pomona (sternwheeler)」の詳細全文を読む スポンサード リンク
