History
The Prairie du Chien Agency was established in 1807 to serve the Indians in Louisiana living along the Mississippi River above the Iowa River; and the Indians living in Indiana Territory north of the Illinois River and west of a line running north and south from a point on the Illinois River about 20 miles north of Peoria. The agency headquarters was located at Prairie du Chien, north of the mouth of the Wisconsin River, on the east bank of the Mississippi River.

Other agencies were formed from the area covered by this early agency -- the St. Peters Agency, the Green Bay Agency, and the Sac and Fox Agency at Rock Island, Illinois. The Prairie du Chien Agency eventually became responsible primarily for the Winnebago Indians, although other tribes continued to have some contact with it.

Because this agency was in existence so early, its supervision was changed rather often as new territories and states came into existence. From its establishment, the agent received some conflicting instructions about to whom he was to report. At various times, he was told to take his instructions from the general Indian agent for Louisiana (Territory), and the Governors of Illinois, Louisiana, Missouri, Michigan, and Wisconsin, as these territories were created, and the Missouri and St. Louis Superintendencies of the Office of Indian Affairs.

In 1837, Prairie du Chien was reduced to a subagency. This subagency was moved to Turkey River by the end of 1840 and the name "Prairie du Chien" was no longer used after 1842.
