A Coos County plat book is the township-by-township atlas farmers, hunters and land buyers around Lakeside have kept in the truck for generations. Here's what a plat book is, where to look for one in Coos County, and the free official map that stays current between editions.
How to use the Coos County plat book
A plat book, sometimes called a land atlas, displays each township in Coos County as a page, with ownership blocks labeled by owner name and rough acreage. Don't confuse it with a subdivision plat on file for lots in Lakeside; that recorded plat is a legal document, while the atlas is a reference.
Finding the tract on the Coos County map
Coos County parcels are viewed through a statewide map, the ORMAP statewide tax lot viewer; zoom toward Coos Bay to reach them. ORMAP gives the map and tax lot number for a county property near Powers; the account details come from the county. Our Coos County, OR page keeps the official link and the maps next door to Powers in one place.
Current and older editions
Try the library in Bandon or a local historical society for older Coos County editions; libraries sometimes keep past atlases for reference. An old atlas can help trace when a tract close to Lakeside split off from a larger farm.
Atlas details and limits
Many atlases add rural residence listings and road maps, handy on back roads near Bunker Hill. Owner names in an older Coos County edition may be decades out of date, so confirm on the county map before contacting anyone near Bunker Hill. For a land purchase near Coos Bay, rely on the county parcel record and a title search, not an atlas.
Old atlases and family history in Coos County
Farm families near Lakeside frequently keep successive editions of the Coos 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 serves as a handy homemade atlas for the area around Lakeside.
The Coos County economy in brief
County Business Patterns counted 1,618 business establishments in Coos County for 2022, led by retail trade, construction, and health care and social assistance. Forestry and logging and fishing, hunting and trapping make up an above-average share of Coos County businesses, a clue to how land around Powers gets used.

Coquille is the county seat, and Bandon, Coos Bay, Lakeside, and Myrtle Point are among the other towns on the county map. Smaller places such as Barview, Bunker Hill, and Glasgow appear on the county map as little clusters of lots. Census Bureau estimates put Coos County at about 64,212 residents in 2023 on roughly 1,596 square miles of land. Outside North Bend, most of the county map is farm, ranch or timber ground with large, irregular tracts.
