History · Twin Lakes
Half of Twin Lakes’ homes were built after 2000
Most of Twin Lakes was built recently: 5% of its homes predate 1940 and the median home dates from 2000. Below: 5 old photos and papers and maps from 1935 on.
Lake County, one of the original 17 counties created by the Colorado legislature in 1861, was named for the Twin Lakes. As originally defined, Lake County included a large portion of western Colorado to the south and west of its present boundaries. The Twin Lakes District has been listed on the National Register of Historic Places since 1974.
