Most of New Strawn was built recently: 9% of its homes predate 1940 and the median home dates from 1977. Below: maps from 1885 on and the census since 1980.
The city of New Strawn came about when John Redmond Reservoir was built in the early 1960s, causing the original town of Strawn to be claimed by the Army Corps of Engineers for flood area. The old city of Strawn is usually available for exploration, but will be underwater if the lake is up. Very little is left of "old" Strawn today, although Main Street can still be traveled when dry.
