In 1945, St, Charles Township formed a cemetery department to assume care and maintenance of North and South cemeteries, which were privately owned at the time. Today, the Cemetery District encompasses six locations:
| Cemetery | Location | Founded | Township Owned | ||
| North | North 5th Ave | 1840 | 1945 | ||
| South | South 7th Ave | 1815 | 1945 | ||
| Little Woods | Dunham Road | 1856 | 1951 | ||
| Union | North 5th Ave | 1900 | 1972 | ||
| Prairie | Crane Road | 1849 | 1957 | ||
| Round Grove | Mosley Lane | 1849 | 1997 |
All six cemeteries (approximately 45 acres) are carefully maintained, although South and Round Grove are no longer active interment locations. The Cemetery District operations are funded by a small tax levy on St Charles Township property.
In November, 2015, the Union Cemetery opened the Columbaria Union Cemetery located to the east end of the cemetery. A Columbaria is a brick or stone structure with niches in which urns containing ashes are buried. The Columbaria Union Cemetery is a beautiful picturesque setting for the interment of cremains.
