[4] Captain Anderson was a prominent boatbuilder and steamboat operator on Lake Washington, and the Issaquah was the most elaborate vessel he had ever built.

In 1891 the eastern terminus of this route connected to a road that ran to Lake Sammamish, Fall City, Preston, Issaquah, North Bend, and Snoqualmie, Washington.

[1] In 1917, the private ferry owners on Lake Washington, which meant Captain Anderson as a practical matter, were undercut by competition from King County.

[5] Two men stayed on Issaquah during the tow, keeping steam up and running the vessel's propellers, as the tug was insufficiently powerful to accomplish the task alone.

After the Carquinez Bridge was completed in 1927, the ferry was shifted to the Mare Island routes from Vallejo, Martinez, and Benicia.

[2] Issaquah can be seen in the 1965 Jimmy Stewart movie "Dear Brigitte" beached on the mud behind the Charles van Damme at the northern end of the Sausalito waterfront.
