Post Falls incorporated in 1891.
Post Falls is named after German immigrant Frederick Post. On June 1, 1871, Frederick Post made a deal with Andrew Seltice, a prominent Coeur d’Alene Indian leader, to obtain more than 200 acres of Spokane River land to start a water powered lumber mill. The purchase of the land is preserved in a pictograph on a granite cliff in Treaty Rock Park. In 1902, the mill was destroyed by fire; the dam was undamaged. In 1905 the mill was rebuilt and resumed operations. A newly formed Washington Water Power Company purchased Post’s site and began making plans to develop a hydroelectric facility.  The new hydro plant at Post Falls would provide power to mines nearly 100 miles away via the longest high-voltage transmission line in the world. The dam and hydro plant is now operated by Avista Utilities and is the site of Falls Park, with observation decks open to the public.
The natural beauty of the surrounding mountains and the river connecting Post Falls with Lake Coeur d’Alene expand the recreation and scenic opportunities. Post Falls has retained the small town look and values continuing draw to residents and newcomers. Today, the city boasts a steady growth in population just over 37,000.
