Anderson Mill is named after Thomas Anderson. He moved from Virginia to Texas in the 1850s. In the 1860s he set up a mill here to make gunpowder for the Confederate Army.
After the war Anderson converted the mill to a gristmill. He later also started a cotton gin. In 1884 the area had a population of 30. It had received a post office in 1876 but this office was discontinued in 1884. After Anderson's death in 1894 the community was abandoned. In 1936 a historical marker was placed to mark the spot. It was not until the late 20th century with the growth of the area as a suburb of Austin that Anderson Mill came back into existence.
The area was included in a municipal utility district (MUD) in 1973, which was first named the Williamson County Municipal Utility District Number 1. The first houses were built in 1975, and construction continued into 1985 with the completion of approximately 3400 homes. In 1988, at the MUD's request, the Texas Water Commission approved a name change to the Anderson Mill Municipal Utility District. The district provided water, wastewater, trash collection. parks and recreation facilities and services. The area has seven neighborhood parks, two junior olympic swimming pools, eight lighted tennis courts, six extensive playscapes, two basketball courts, three sand volleyball courts, six pavilions of various sizes, an athletic field with both soccer and softball fields and nearly six miles of hike and bike trails that meander through the neighborhood following Lake Creek and its tributaries. In 2008, the growing City of Austin annexed the MUD and took over the water and wastewater services. An agreement with the City of Austin and the MUD allowed the residents of the district to voted to create the Anderson Mill Limited District which would retain possession of all the park and recreation facilities. The Limited District would maintain all the park and recreation facilities and provide recreation services to district residents. This service would be supported by both activity fees and a property tax.
