Record
About Monohon
Monohon was a town located on the east side of Lake Sammamish (then known as Lake Squak), near the present-day intersection of East Lake Sammamish Parkway and SE 33rd Street in the city of Sammamish. The community was originally part of a town named Donnelly, founded by Simon Donelly who built a sawmill there, but then grew big enough and was far enough away from Donelly that residents created a separate town, Monohon, in 1888.
