Hunting for the latest Washington County plat book? It's a printed atlas of landownership, usually by township, useful for farms near Afton State Park. What this county guide covers: what's in a plat book, where to look for printed copies, and how the county viewer fills the gaps, at least around Siegel.
The Washington County plat book: start here
For a home near Stillwater, plat books are commercial atlases, with owner names on each tract, page by page across the county.
Pulling up a parcel
Begin with the Washington County ArcGIS parcel map; it covers each assessed parcel around Siegel and Mississippi National River and Recreation Area. When a rural tract has no street number, follow Interstate 494 on the aerial and select the outline. For property near Bayport, copy the parcel ID before closing the panel; every records desk in the county will want it.
Buying or borrowing a copy
Editions come and go depending on publishers, check with local offices and farm stores near Mississippi National River and Recreation Area.
The free online alternative
The Washington County ArcGIS parcel map is updated more often than any atlas, for tracts near Forest Lake.
Limits of the parcel data
With a lot near Siegel, listed acreage is an assessed number; only a licensed surveyor sets the real boundary on the ground. For acreage around Dellwood, owner names and values update on a schedule, so a deed recorded last month might lag behind.
How land is described here
Minnesota uses the Public Land Survey System, which means a tract near Mississippi National River and Recreation Area is described by section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Afton State Park can be irregular. Write down the legal description for the tract near Arcola when you talk to a surveyor.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed through the County Recorder; the parcel line is a drawing of it, and that holds around Basswood Grove too. If you're looking near Siegel, inherited tracts in the county may sit on many deeds, and a title company can sort it out on a real sale.
Not the same thing
On ground around Dellwood, a plat book is not a recorded plat: the recorded plat at the County Recorder is a legal document, and the atlas is just a guide.
Next door to the county, especially near Cottage Grove.
Washington County meets Anoka County, Chisago County, Dakota County, Ramsey County, and Pierce County, WI; every one of them runs a separate parcel map. Acreage along the edge near Cottage Grove may be split across two assessors' files, so open the neighboring map before you assume the acreage. For a parcel near Stillwater, our state page links every neighboring county map for Minnesota.

On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Cottage Grove, but coverage can be spotty out of town. A printout of the tract near Stillwater helps when you meet an owner or agent.
Common uses
Buyers and seed dealers around Birchwood Village rely on them to see ownership across many tracts at once.
Which office to call
Recorded documents for a parcel near Arcola sit in the index kept by the County Recorder, sometimes only in person. Questions about what you can build around Forest Lake go to planning, building or health offices, town or county, depending on location.
Places you'll see on the map
Stillwater holds the county offices, which is where the courthouse records live. You'll also find Afton, Bayport, Birchwood Village, and Cottage Grove, where town lots give way to larger tracts. Around 278,936 people call Washington County home (Census Bureau estimate, 2023) across about 385 square miles. The county was formed in 1849, which matters when you trace an old farm's title around William O'Brien State Park. Features like Afton State Park help you orient on the aerial around Maple Island.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
