Where to find the official Nicollet County plat map

The lay of the land in Nicollet County
Besides St. Peter, which serves as the county seat, the map covers Courtland, Lafayette, Mankato, and Nicollet. Out in the countryside, Bernadotte, Klossner, and New Sweden appear as small knots of lots along the road network. Census Bureau estimates show 34,242 residents in 2023 and around 449 square miles of land in the county. That density means a real mix on the map: platted neighborhoods near St. Peter, and larger tracts on the rural roads. On the parcel layer, Fort Ridgely State Park and Minneopa State Park show up as public ground, and the private tracts along their edges are worth checking line by line.
How accurate are Nicollet County, MN property lines?
Parcel boundaries on the Nicollet County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. The section grid shapes many farm tracts around Norseland; boundaries often follow quarter-section lines you can spot on the map. For rural ground near Norseland, a recorded survey or a new one is the only reliable source for the true line.
Work and land use in Nicollet County

Wooded parcels between Mankato and Lafayette may be managed timber, so read the aerial history before you assume a tract is untouched.
