History
Timber Lake was founded in 1910 with the arrival of the Chicago, Milwaukee, St. Paul and Pacific Railroad into the area. Despite the name, very few trees grew at the lake near the town site. During drought, the lake is a mere mudhole. On April 21, 1946, a large tornado struck the area in and around Timber Lake. The U.S. Weather Bureau published a paper in 1946 stating the width of this tornado was , which would make this the widest tornado ever documented in history, surpassing the 2013 El Reno tornado. However, this is outside the period of reliable documentation accepted by the National Weather Service; 1950–present.
