Colusa County, California
Colusa County · Colusa is the seat · Sacramento is the capital of California · Williams is a city · Arbuckle is a town · Maxwell is a town · Sutter is a different county
Colusa is the seat. Sacramento is the capital. Williams is a city, not the hall.
Colusa County, California, was created 18 February 1850 as one of the original twenty-seven counties, and named for Rancho Colus — not the City of Williams as the whole county. Colusa is the county seat. Sacramento is the capital of California. Colusa is not the capital. Williams is not the capital. Do not read this page as Autauga-with-a-levee. Do not read this page as Alameda-with-rice. Prattville is Autauga. Oakland is Alameda. Neither is this oval.
Williams is a city — not the hall. The City of Colusa is a municipality — not the whole county government. Arbuckle, Maxwell, Princeton, Grimes, College City, Stonyford, and Lodoga are unincorporated communities — remainder, not a second seat. Glenn is north — Willows is that hall. Sutter is east — Yuba City is that hall. Yolo is south — Woodland is that hall. Lake is west — Lakeport is that hall.
This page is Side One for the place. The Sheriff’s job — valley remainder patrol and the Bridge Street jail this badge still holds — is taught at Office of the Sheriff — Colusa County.
Five Supervisors at 547 Market. They do not sit as the State Assembly.
Colusa is a general law county. A five-member Board of Supervisors, elected by district, sits at 547 Market Street, Room 102, Colusa, CA 95932. They fund roads, the Market / Oak courthouse campus, and the Sheriff’s budget. They do not hire the Sheriff. The people do. Colusa City Council is a city body. Williams City Council is a city body. The California Legislature sits in Sacramento. None of those is this Board.
Colusa Superior Court lists Dept. 1 at 547 Market Street and Dept. 2 at 532 Oak Street. Do not invent one rice field as the whole map. Confirm live at countyofcolusaca.gov and colusa.courts.ca.gov.
The Sheriff is a county officer (California Constitution Article XI; Government Code § 24000). This Sheriff is not on the 2026 gubernatorial table. Elections Code § 1300 (AB 759, 2022) moved sheriff and district attorney to the presidential primary. A sheriff elected in 2022 serves a six-year term; the next regular is the 2028 presidential primary. Colusa has no charter that could have locked a gubernatorial-year date before 1 January 2021. Last regular 7 June 2022. Take office at noon on the first Monday after January 1 succeeding election (Gov. Code § 24200). The Governor is 2026. That is a different desk in Sacramento.
The Sacramento is a river. Arbuckle is a town. Sutter is a different county.
Interstate 5 and State Route 20 meet on this map. The Sacramento River is water, not a Sutter badge. Rice is a crop. The Sacramento National Wildlife Refuge is a refuge — not this government. The west-side hills climb toward Lake and the Mendocino National Forest. Staff who paste an I-5 photograph onto Market Street, or treat Colusa as the capital, or file Williams as this county government, or rewrite this county as Autauga-with-a-levee, are on the wrong county.
How a valley public finds Market, Oak, and Bridge
Board of Supervisors: 547 Market Street, Room 102, Colusa. Superior Court: 547 Market (Dept. 1) and 532 Oak (Dept. 2). Sheriff Administration and Jail: 929 Bridge Street, Colusa, CA 95932 — Sheriff (530) 458-0200, jail (530) 458-0205. Elections / Clerk-Recorder: 546 Jay Street, Suite 200. Confirm live at countyofcolusaca.gov. A student who only knows a rice postcard, or a Sacramento photograph as this county, or treats Williams City Hall as the jail, has not found this campus.
Bridge Street still jails. Colusa PD does not. Williams PD does not.
Crime in unincorporated Colusa — Arbuckle, Maxwell, Princeton, Grimes, Stonyford, Lodoga, and the remainder — is this Sheriff. Crime in the City of Colusa is often Colusa Police at 260 6th Street. Crime in Williams is often Williams Police at 700 North Street. This Sheriff is not those municipal departments. Colusa County Jail at 929 Bridge Street is this Sheriff’s house. Official doors did not show a separate county Department of Corrections taking this house — do not invent a jailer split.
CDCR is not this Sheriff. CHP is a state badge on I-5. Do not send a family looking for a county booking to Colusa PD, to Williams PD, or to a Sutter door.
Care without inventing rice as a second government
A peace order served in Arbuckle. A court-ordered transport from Bridge Street to Market Street. Boating on the Sacramento the office actually posts. Do not invent a church. Do not invent a refuge as this oval. Do not invent Sacramento as this hall.
What Colusa actually watches
Court calendar on Market and Oak. A wreck on I-5. Fog on the rice checks. High water on the Sacramento. Fire on the west-side timber. Coordination with Colusa PD, Williams PD, and CHP without becoming those departments. Coordination with Glenn’s Sheriff or Sutter’s Sheriff is mutual aid between two offices, not a merger. Rice is agriculture. I-5 is a highway. Neither is Williams PD as this oval.
