Organization of Summit Township was approved by the Nobles County Board on May 20, 1873. The first township meeting was held on June 5, 1873. The original name of the township was Wilson Township. However, the county board was informed by the state auditor's office that another Wilson Township existed elsewhere in the state. The township was briefly renamed Akin Township on June 15, 1874, but once again, the county was informed that another Akin Township existed within the state. On July 27, 1874, the township was given its present name of Summit Lake Township in honor of a lake in section 11 of the township. Presently, two Wilson Townships currently exist within Minnesota, one in Cass County and the other in Winona County. There is no Akin Township anywhere within the state. Summit Lake, the namesake of the township, no longer exists having been drained and lost in the passing years.
