Lake Dorothy is a lake in King County, Washington. First labeled on Oliver P Anderson's "New Map of the County of King, State of Washington, 1894"; the name was bestowed by Anderson for his daughter Dorothy Louise Anderson (1893-1912), a member of Sigma Kappa sorority. It is one of the largest lakes in the area and is the source of the East Fork Miller River.

Waterfalls

A number of waterfalls surround Lake Dorothy. Florence Falls (76 ft) is located over a promontory a short distance downstream from the outlet. As Florence Falls reaches Camp Robber Creek a second waterfall is produced by a series of slides and cascades, 76 ft Camp Robber Cascades.

Access

The lake can be reached by the Dorothy Lake Trail which is about 2 miles to the lake. The trail continues another 2 miles along the lake’s shore to its south end. After that it continues on, climbing up from the lake and eventually climbing over a ridge before descending to Bear Lake and the Taylor River.
