Eagle Creek is the name of a post office as well as of a stream. There are many streams of the same name in the state. A. C. Cogswell, postmaster at Eagle Creek in 1925, wrote the compiler that the place was called Eagle Creek as early as 1844 and that the name originated with Native Americans because there were so many eagles along the stream. Eagle Creek post office was established on August 26, 1867, with Philip Foster as postmaster.
