The steamboat Hassalo, built in 1880 at The Dalles, Oregon, was a wooden-hulled vessel measuring approximately 160 feet (49 meters) in length, with a beam of 30 feet (9 meters), and a depth of hold of 6 feet (2 meters). Rated at 462 tons, it was powered by twin single-cylinder steam engines, each with a 17-inch bore and a 60-inch stroke, which drove a sternwheel that propelled the vessel through the Columbia River and Puget Sound regions. Hassalo was notable for its service along the Middle Columbia River, specifically the stretch between the Cascades of the Columbia and The Dalles, Oregon. This region was characterized by rapids and natural barriers, requiring complex navigation and portage routes. As the first steamboat built for the Oregon Railway and Navigation Company, Hassalo played a vital role in regional transportation before the advent of railroads. Its early captains included Fred Wilson, H. F. Coe, and John McNulty. A defining moment in Hassalo's history occurred on May 26, 1888, when it became famous for running the Cascades of the Columbia at speeds approaching 60 miles per hour. This feat was witnessed by a large crowd of around 3,000 spectators during a well-publicized excursion, marking a significant achievement in steamboat speed and navigation. The vessel expertly navigated the six-mile-long rapids in just seven minutes, crossing the turbulent waters with remarkable agility and speed, and then continued its journey downriver to Portland. Following its fame on the Columbia River, Hassalo was transferred to Puget Sound, where under Captain O. A. Anderson, it served routes including Bellingham and the Olympia-Tacoma-Seattle corridor. In 1890, Hassalo was involved in a collision with the smaller sternwheeler Otter, which resulted in Otter being beyond repair. By 1892, Hassalo returned to the Columbia River and was converted into a towboat. The vessel remained in service until 1898, when it was dismantled, marking the end of its notable maritime career.
