Steffen for pioneer businessman Jacob Kamm and worked on the route along the lower Columbia river from Portland to Astoria, Oregon.

[5] As built, Undine was 150 ft (45.72 m) long, exclusive of the extension of the main deck over the stern, called the fantail, on which the stern-wheel was mounted.

[3] From 1888 to 1895 Undine ran primarily on this route, with occasional trips to Astoria, Oregon and excursion runs.

[6] In early May 1888, Undine made the 18 mile run from Vancouver to Portland in 58 minutes carrying 100 pounds of steam.

[9] On a school excursion on the evening of Monday, May 19, 1890 from Portland to Oregon City, Undine carried 450 passengers, of which there were about 300 who paid fares.

[10] Hauser's method was to book a band, charter a steamboat, and sell tickets, hopefully making a profit.

[10] Other times, such as on Saturday, July 27, 1889, he lost money, about $150, when he charted Undine for a Portland-Astoria run, hired the band of the First Regiment, Oregon National Guard, but was not able to sell many tickets.

[10] Excursion managers booked Undine for a trip from Newberg, Oregon up the Columbia river on Saturday, June 20, 1891.

For example, on June 30, 1890, Undine towed a barge from Kalama, Washington laden with a steam locomotive and a passenger coach intended for the Ilwaco Railway and Navigation Company.

[14] For the most part of Undine’s early years, Fred S. Shepard was the boat's chief engineer and Frank Malmquist was its purser.

[17] On the night of September 3, 1891, near Vancouver, Washington, crewmen on Undine found and recovered from the Columbia river the body of a Native American man whose hands had been tied by a chain wrapped around his body, and the chain secured to a heavy piece of railroad iron.

[22] Undine transported the troops from Vancouver to Kalama, Washington where they disembarked to proceed to Seattle by train.

[27] In March 1905 Undine was hauled out, for the first time in twelve years, at the Portland Shipbuilding Company's yard.

[28] In August 1905 Undine was employed on sightseeing trips up the Columbia River to Cascade Locks and Canal.

[30] The change was made necessary by need to find a replacement for the sternwheeler Dalles City, which had sunk at Curtis Landing a few days before.

[30] Dalles City was returned to service on March 16, 1906, after which Undine was hauled out at Portland Shipbuilding for a hull inspection.

At the conclusion of the funeral, Undine carried the remains to River View Cemetery to be interred in the Shaver family plot.

[36] On July 11, 1932, crewmen who were employed on Undine during March and April of that year brought suit in the United States District Court to force the sale of the steamer and “her engines, tackle, apparatus and furniture” to satisfy their claims for wages.

[38] On August 1, 1932 a motion for an order to the U.S. marshal to sell the boat was presented for hearing before U.S. district court judge John H. McNary (1867-1936).

[39] On October 31, 1935, the Bureau of Navigation and Steamboat Inspection, through Milton A. Miller, Collector of Customs, announced that it had granted permission to Undine, official number 221499, to change its name to The Dalles.
