HistoryA character grade: shown, never part of Big Lake Township’s overall grade.
Minnesota towns list about as much on the Register as the country (a typical Minnesota town has 2.1 per 10,000 residents, the U.S. 2.4), so Big Lake Township’s 0.0 sits below most of its state (23% of Minnesota towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on two of the three inputs, so a change in either one moves the letter more than it would with three. The pre-1940 share (±1.5 points) is firm at this size.

What stands out about Big Lake Township’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Big Lake was originally established to harvest ice in both of its towns' lakes (Big and Mitchell Lakes). Due to the rich amount of ice Big Lake provided, it needed to be transported quickly, enabling Big Lake to be suitable for a railway station which was built in 1871. Big Lake was served by both the Great Northern Railway and Northern Pacific Railroad, later Burlington Northern Railroad, now BNSF Railway.
The city was host to a station of both GN and NP railways until the NP station burned in 1918, in later years both railroads shared a depot. The depot no longer stands.
