Looking for a Modoc County plat book? A plat book shows owners and tract lines on township pages, popular with hunters, farmers and buyers near Daphnedale Park. In this county guide: what's in a plat book, where to look for printed copies, and the free online map that stays current around Goose Lake.
Getting started with the Modoc County plat book
For a home near Medicine Lake Volcano, plat books are commercial atlases, showing rural owners and tract lines, page by page across the county.
The viewer Modoc County publishes
Your first stop is the Modoc County parcel viewer; it covers every tax parcel in the county, Tule Lake Unit included. If you're looking near California Pines, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Tule Lake Unit, copy the parcel ID while you have it open; each office in the county will want it.
Limits of the parcel data
Out toward Adin, listed acreage is an estimate; just a licensed surveyor can set the real corners on the ground. Out toward Medicine Lake Volcano, records update in batches, so a deed recorded last month can take weeks to appear.
Buying or borrowing a copy
Editions come and go depending on publishers, check with local offices and farm stores near Tule Lake Unit.
Between editions
Between printed editions, the Modoc County parcel viewer shows current owners, across the county.
Printing your own
Screenshot each section of the viewer around Medicine Lake Volcano to build your own up-to-date atlas.
Land on the county line
Modoc County meets Lassen County, Shasta County, Siskiyou County, Washoe County, NV, and Klamath County, OR; every one of them runs a separate parcel map. Acreage along the edge near Alturas can be split in two county records, so open the adjacent map before you assume the acreage. On ground around Tule Lake Unit, the Platbookmapper state page links every neighboring county map for California.
Atlas or legal document
For property near Cedarville, 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.
Getting answers from the right desk
Questions about value or the owner field for land near Adin belong with the County Assessor, the office behind the parcel record. Questions about what you can build around California Pines need the planning or permitting office, town or county, depending on location.
Backing up the map with records
Before you sign anything, pull the recorded deed from the County Recorder; the viewer just points to it, and that holds around Tule Lake Unit too. Inherited tracts near Medicine Lake Volcano may sit on a long string of deeds, and a title company is worth hiring before a purchase.
Modoc County in a few facts
Alturas is the county seat, which is where the courthouse records live. Smaller places on the map include Adin, California Pines, Canby, and Cedarville, where town lots give way to larger tracts. Around 8,500 people call Modoc County home (Census estimate, 2023) spread over some 3,948 square miles. Features like Medicine Lake Volcano, Goose Lake, and Tule Lake National Wildlife Refuge are easy to spot when you zoom out from Medicine Lake Volcano.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Canby, but coverage can be spotty out of town. A saved image of the lot near Alturas and its lines keeps working without signal.

A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Tule Lake Unit vary in size. Write down the legal description for the tract near Cedarville when you talk to a surveyor.
Common uses
Farmers, hunters and appraisers near California Pines use plat books for a big-picture view of who owns what.
