Somewhere between Williams and the Butte County line is a tract you want to know more about. The Colusa County GIS map is the free, official place to start.
The sections below cover the map itself, the towns from Williams to Princeton, and the deeds and surveys that settle what the map can't.
The lay of the land in Colusa County
On the map, Colusa anchors the county as its seat, with Williams spread around it. Smaller places such as Arbuckle, Grimes, and Lodoga show up as clusters of lots along the roads. By Census Bureau figures, the county had roughly 22,037 residents in 2023, spread over about 1,151 square miles of land. Outside Williams the parcels open up quickly into farms, timber and small acreage homesites. The Sacramento River is part of the Colusa County landscape, and creek or shoreline tracts are common there. Butte Sink National Wildlife Refuge, Colusa National Wildlife Refuge, and Delevan National Wildlife Refuge are a big draw, and the private tracts that border public land are often the first ones hunters and cabin buyers ask about.
Where to find the official Colusa County GIS map
The official map is the Colusa County ArcGIS parcel map, which runs on an Esri ArcGIS web map. Try the search box with an Arbuckle street address first; for open land near Princeton, it's faster to pan and click. We keep the link current on our Colusa County (CA) directory page, next to the neighboring maps.
How accurate are Colusa County, CA property lines?
A lot line on the Colusa County GIS map near Williams is a drawing based on deeds, not a measurement taken on site. California uses the Public Land Survey System, so rural deeds in Colusa County often describe land by section, township and range, and you can match the call to the grid on the map. For rural ground near Princeton, a recorded survey or a new one is the only reliable source for the true line.
Where Colusa County deeds and plats are kept
Every line on the Colusa County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Check the county government website to see which office records deeds for land near Princeton. If you need a plat for a lot in Arbuckle, look for the plat book and page or the subdivision name in the parcel record, then request that document from the recording office.

Private and public hunting ground in Colusa County
Before you scout a new spot near Arbuckle, pull up the parcel layer and see how many owners share that stretch of woods. If you're hunting public ground like Butte Sink National Wildlife Refuge and Colusa National Wildlife Refuge, use the parcel map to see where the public boundary meets private land. The California Department of Fish and Wildlife publishes the seasons and public-land maps, so pair those with the parcel layer. Ask owners near Arbuckle early, ask politely, and send a thank-you after the season.
