Brewster’s population peaked in the 1970 census when it hit 563. Today it’s a little over 400. At one time it had it’s own school district, but later paired and shared with Sioux Valley and Round Lake to create Sioux Valley – Round Lake – Brewster.
Today they are Round Lake Brewster. Sioux Valley was a township and a cross roads with a couple of businesses, never really a town, but prior to Brewster pairing with them, the district was Sioux Valley – Round Lake.
