McMillan is a town in Marathon County, Wisconsin, United States. It is part of the Wausau, Wisconsin Metropolitan Statistical Area. The population was 1,968 at the 2010 census.[3] The unincorporated community of McMillan is located in the town. A section of the Mead Wildlife Area is also located in the town.
According to the United States Census Bureau, the town has a total area of 89km2, of which 88.4km2 is land and 0.5km2, or 0.59%, is water.[4]
The six mile square that would become McMillan was first surveyed in August/September of 1851 by a crew working for the U.S. government. In November 1853 another crew marked its section corners, walking through the woods and wading the streams, measuring with chain and compass.[5] [6] When done, the deputy surveyor filed this general description:
This Township contains several small swamps, and some of considerable size. The(sic) is a great part of the land which is of poor quality, particularly so, that part of it which contains Hemlock & Fir. The Soil(?) a poor quality, being clay [undecipherable] and rough & uneven. There is a great part of it that the rocks lay(?) on the surface. The land which contains Hardwood(?) is of good quality & would make good farming land(?).
The Pine in this Township is of Poor quality & scattering. This Township is well watter(sic), most of the streams [undecipherable]. There is one stream which runs through the Township is of sufficient size for Milling purposes being [indecipherable] high banks & rocky bottoms. There is no improvement in this Township.[7]
In 1874 B.F. and Charles McMillan built a sawmill on the Little Eau Pleine River, five miles north of the young town of Marshfield. The mill prospered and workers settled nearby. A school was started in 1881. A village of McMillan was incorporated with its own post office and the population grew to at least 200. But the nearby timber was eventually exhausted and in 1911 the sawmill closed. Most of the village gradually faded away, now leaving only the neighborhood known as "Sugarbush."[8]
As timber was cut, settlers bought the stump-clogged forties and began to carve out farms. These eventually focused on dairy, shipping their milk to local cheese factories.[8]
In the early 1900s a community called Riverside coalesced where T crosses 97 and the Little Eau Pleine. It had a saloon, a grocery store, a feed mill, a blacksmith, and a school. It eventually faded away too.[8]
After the timber was cut, some of the low land on the west side of McMillan wasn't very suitable for farming. Little was done with it, it burned about every ten years, and much of it went tax delinquent. Krasin and Hartle bought some forties and tried to run a fur farm there. In 1948 the county made 37 forties a public hunting ground. That area reaches from west McMillan into the Town of Spencer along the Little Eau Pleine and has evolved into the McMillan Marsh Wildlife Area - now managed as part of the Mead Wildlife Area.[9]
