Looking for a Delaware County plat book? Plenty of people around Dundee still want a paper atlas with owner names on every section. Here's what a plat book is, where to look for one in Delaware County, and the free official map that stays current between editions.
What's inside a county plat book
Think of the Delaware County plat book as a bound, printed version of ownership: township pages, owner names on each tract, and road maps for places like Earlville. Don't confuse it with a subdivision plat on file for lots in Earlville; that recorded plat is a legal document, while the atlas is a reference.
Opening the Delaware County parcel viewer
Delaware County publishes its parcels on the Delaware County Beacon site, which runs on Schneider Geospatial's Beacon platform, free to use for a lot in Delhi or a tract around Dundee. Search a Dundee address on the county search page, read the report, then jump to the map to see that parcel's outline. For a backup route to the map covering Dundee, our Delaware County directory entry keeps the link current.
Delaware County land records
Deeds and plats behind the Delaware County map are kept by the county's recording office; the official Delaware County website names which office that is. A deed book and page or instrument number on the county record is the fastest way to order the document for a lot in Manchester.
Where Delaware County plat books turn up
Whether a current Delaware County edition exists varies, so ask locally in Manchester before ordering; county offices often know if one is in print. Older editions are useful for family history around Earlville, showing who held a farm decades ago.
From Manchester to the back roads
Town lots cluster around Manchester, the county seat, and Colesburg, Delaware, Delhi, and Dundee. Unincorporated communities in the county, including Almoral, Ehler, and Forestville, show up as small groups of parcels along the roads. Census Bureau estimates put Delaware County at about 17,600 residents in 2023 on about 578 square miles of land. Outside Delhi, most of the county map is farm, ranch or timber ground with large, irregular tracts.
Reading a Delaware County atlas page
A typical atlas page for a township near Earlville displays sections, roads and streams, with each ownership block labeled. Acreage printed in a county atlas is rough; the deed and a boundary survey decide the real figure for a tract around Dyersville. If you use a plat book for hunting permission near Earlville, recheck the titleholder on the county map first.
Making your own atlas of Delaware County
Farm families near Colesburg often keep successive editions of the Delaware County plat book, which together show how ownership shifted over decades. If you can't track down a printed edition, a screenshot of each township from the county map makes a serviceable homemade atlas for the area around Colesburg.
The Delaware County economy in brief

Compared with national shares, Delaware County leans toward agriculture and forestry support services and chemical manufacturing, which shapes demand for land near Dundee.
