In 1860, after only 8 years of operation, the sawmill closed. In 1869, a flour and grist mill were constructed and operated until the late 1880s. In 1874, Charles H. Burwell came to manage the Minnetonka Mill Company, and he built a Victorian home on the north bank of Minnehaha Creek (Minnetonka Boulevard at McGinty Road East) for his family. The Charles H. Burwell House is now on the National Register of Historic Places and is owned by the city. There were two other mills in Minnetonka. The St. Alban's Mill, which was less than downstream from Minnetonka Mills on Minnehaha Creek, operated as a flour mill from 1874 to 1881. A grist mill built on Purgatory Creek was washed out in a flood shortly after construction. Minnetonka Mills, with its post office and port for Lake Minnetonka, was the principal business and trading center for a large area until the 1870s.
