Ancient indigenous peoples constructedearthworks that expressed their religious and political concepts. An early European explorer counted 72 such earthen mounds in what is now Waupaca County, many of them in the form ofeffigy mounds, shaped like "humans, turtles, catfish and others."[7] There were 52 mounds constructed around what is now called Taylor Lake. Most mounds were lost to agricultural development. One mound, shaped like a catfish, is still visible in a private yard along County Hwy. QQ, just east of Taylor Lake. The site was marked by a local women's club with a commemorative plaque installed on a large stone.[7]
Under pressure from European-American development, theMenominee people ceded their title to the United States for these lands by treaty in 1852. Following that, the flow of new migrant settlers greatly increased from the East, with people moving from New England, New York, and Ohio. They developed the land primarily for agricultural use in the early decades, also quickly establishing sawmills on the rivers.
In the 1870s railroads were constructed in the county: theWisconsin Central in 1872 and the Green Bay and Minnesota Railroad (later known asGreen Bay, Minnesota & St. Paul) in 1873. These improved the county's connections to markets for its lumber and other products. For a period, entrepreneurs and merchants gained high profits from the lumber industry, establishing many fine homes in the larger cities.
According to theU.S. Census Bureau, the county has a total area of 765 square miles (1,980 km2), of which 748 square miles (1,940 km2) is land and 17 square miles (44 km2) (2.3%) is water.[8] The water includes 22 lakes that form the Waupaca Chain O' Lakes. These lakes are majority spring fed and connected by theCrystal River outlet.[9] Waupaca County is also home toPartridge Lake on theWolf River and the Waupaca River.

Waupaca County has long been one of the most Republican counties in Wisconsin. Only two Democrats have carried the county at the presidential level since the formation of the Republican Party –Franklin D. Roosevelt in 1932 and 1936, andBarack Obama in 2008, and in 1936 Roosevelt only won by plurality because of a sizeable vote forUnion Party nomineeWilliam Lemke. It was one of only three Wisconsin counties, alongsideWalworth andWaushara, to vote forBarry Goldwater overLyndon Johnson in 1964.
In other statewide races, the county is equally Republican. The only Democratic gubernatorial candidate it has backed since at least 1908 isAlbert Schmedeman in 1932.[17] SenatorsHerb Kohl in 2006 andWilliam Proxmire in 1976 and 1970 did carry Waupaca County when they swept every county in the state, but no other Democratic senatorial candidate has won the county sincethe Seventeenth Amendment.
