Welcome To Osage County
Oklahoma’s Largest County
At the Osage County Sheriffโs Office, our mission is to provide a solid foundation on which the residents of Osage County can thrive. We are committed to building public trust and fostering safe, secure communities through professional, high-quality professional law enforcement.
Osage County holds a unique place in Oklahomaโs history and geography. As the stateโs largest county by area, it was established in 1907 when Oklahoma gained statehood. The countyโs name and heritage are deeply tied to the federally recognized Osage Nation, whose reservation boundaries are coextensive with the county itself. This land became the Osage Nation Reservation in the 19th century following the relocation of the Osage people from Kansas.
The county seat, Pawhuska, is one of the first three towns founded in the county and remains a hub of history and culture. As of the 2020 Census, Osage County had a population of 45,818 residents.
According to the U.S. Census Bureau, the county spans an impressive 2,304 square miles (5,970 kmยฒ), with 2,246 square miles (5,820 kmยฒ) of land and 58 square miles (150 kmยฒ) of water, accounting for 2.5% of its total area. Much of the landscape is part of the Osage Plains, characterized by open prairie, while the eastern portion features the rolling Osage Hillsโan extension of Kansasโ Flint Hills. Nature enthusiasts can also explore the renowned Tallgrass Prairie Preserve, located just north of Pawhuska, where remnants of the once-vast tallgrass ecosystem are carefully preserved.

On the evening of June 21, 2026, an Osage County Sheriff's Deputy conducted a traffic stop on a red Jeep Cherokee near Tulsa in Osage County after observing the vehicle repeatedly fail to maintain its lane of travel.
During the stop, deputies learned the driver did not possess a valid driver's license and the vehicle was not insured. Deputies also discovered a five-year-old child was riding in the back seat without being properly restrained in a child safety seat and was not wearing a seatbelt.
While speaking with the driver, deputies observed an open container of alcohol inside the vehicle. The driver admitted consuming alcohol prior to driving and agreed to participate in Standardized Field Sobriety Tests.
Based on the totality of the investigation, deputies determined the driver was impaired. A preliminary breath test indicated a BAC of 0.17, more than twice the legal limit.
The driver, identified as Mikah Mattie Marie Washington, was arrested and booked into the Osage County Jail on the following allegations:
โช๏ธ Driving Under the Influence (DUI)
โช๏ธ Child Endangerment
โช๏ธ Failure to Properly Restrain a Child
โช๏ธ Driving Under Suspension
โช๏ธ Failure to Maintain Security Verification (Insurance)
โช๏ธ Failure to Maintain Lane
After being advised of Oklahoma's Implied Consent Law, the defendant initially agreed to submit to the state's chemical test but later refused testing at the testing facility.
Driving under the influence places everyone on our roadways at risk, especially innocent children who rely on adults to make responsible decisions. The Osage County Sheriff's Office remains committed to removing impaired drivers from our roads and protecting the safety of our communities.
This is an arrest not a conviction.

Due to heavy rainfall across Osage County, numerous roads are experiencing high water and flooding. Gray Horse Creek at State Highway 20 is one of the areas impacted, and motorists should expect additional flooded roadways throughout rural Osage County. Flood warnings are in effect for portions of the county as excessive rainfall continues to create hazardous travel conditions.
Drivers should use extreme caution, especially where low-water bridges and other locations that traditionally flood may quickly become impassable.

Our deputies are monitoring conditions throughout the county and will continue to respond to reports of flooded roadways as they develop.
Please slow down, stay alert, and help keep yourself and others safe by avoiding flooded roads. If you encounter a flooded roadway, report it to local authorities if it has not already been marked.
Your destination is never worth risking your life. Stay safe, Osage County. … See MoreSee Less

On Wednesday, June 24, 2026, OBNโs Marijuana Enforcement Teams (MET) and the Osage County Sheriffโs Office served a Search Warrant at Linda Wood LLC (10624 State Highway 11) in Barnsdall, Oklahoma as part of an ongoing criminal investigation.
โThis investigation involves illegal cultivation of marijuana at this location, black-market marijuana production and distribution, and cultivation of marijuana without an OBN Registration.โ—OBN PIO Mark Woodward
Agents and Deputies seized 12,899 marijuana plants and 840.8 pounds of processed marijuana. One person was arrested and five people were taken into the custody of ICE. More arrests are expected as this case moves forward.
Agencies involved in the Search Warrant included OBN MET, the Osage County Sheriff's Office, the Oklahoma Department of Agriculture, Food and Forestry, U.S. Immigration and Customs Enforcement, the Barnsdall Police Department, and District 1 County Commissioner Anthony Hudson's Office.
"Illegal marijuana grows operating outside Oklahoma's regulatory system have no place in Osage County. This investigation is an example of what can be accomplished when local, state, and federal agencies work together toward a common goal. We will continue to aggressively pursue criminal organizations that exploit our communities and operate outside the law."

As we move into the second half of 2026, I would like to provide an update on the status of operations within the Osage County Sheriffโs Office and share several projects that reflect steady, measurable progress in strengthening our infrastructure, improving operations, and enhancing our ability to serve the citizens of Osage County.
One of our primary areas of focus this year has been continued improvements to the Osage County Jail. Recently, we completed a large-scale kitchen plumbing construction project that addressed a significant portion of the facilityโs original cast-iron plumbing system. Much of this aging infrastructure had deteriorated beyond its useful life and was no longer functioning properly. The project replaced critical sections of piping serving the kitchen area, and we have already seen substantial improvements in reliability and overall performance. Investing in our jail infrastructure remains essential to maintaining safe, efficient, and cost-effective operations.
Many residents may have noticed new construction taking place on the Sheriffโs Office grounds over the past several months. We have successfully completed two new buildings at the facility. The first, a smaller storage building, replaces a structure that was destroyed during the severe windstorm event last summer. By utilizing insurance funds from the loss of the original building, we were able to complete this project with minimal impact on county resources.
The second project is a new 7,500-square-foot multipurpose facility that will serve as overflow evidence storage for the Sheriffโs Office while also providing operational space for Osage County Emergency Management. This facility represents a significant investment in both public safety and emergency preparedness. We anticipate occupying the building alongside Emergency Management personnel before the end of the year.
Our School Resource Officer (SRO) Program successfully completed another school year and continues to grow through the dedication and professionalism of our deputies assigned to our schools. Every school district has unique needs, and we continually evaluate ways to improve services and strengthen partnerships with school administrators, teachers, students, and parents. Throughout the school year, our SRO deputies provided approximately 9,270 hours of service within Osage County schools. Their responsibilities extend far beyond the classroom, as they routinely attend athletic events, extracurricular activities, school functions, and community events to help ensure the safety and security of students, staff, and visitors. Their commitment has fostered positive relationships and strengthened trust between law enforcement and the communities we serve.
Our inmate work crew program continues to provide valuable service throughout Osage County. Trustee crews have assisted communities with cleanup projects, roadside litter removal, and a variety of labor-intensive tasks that benefit local residents. These crews have removed thousands of pounds of debris from county roadways while helping improve the appearance of our communities. The program not only provides a benefit to taxpayers but also offers inmates an opportunity to give back and contribute positively to the communities they have impacted.
Another significant issue we are actively addressing is the long-term water infrastructure serving the Osage County Jail and Sheriffโs Office. Reliable water service is critical to maintaining jail operations, particularly during maintenance periods, service interruptions, or emergencies affecting municipal water systems. Working alongside the Board of County Commissioners and the City of Pawhuska, we are exploring options to strengthen our water supply capabilities. One solution currently under consideration is the rehabilitation and reuse of an existing water tower near the Osage County Fairgrounds. If feasible, this project would provide additional water storage capacity and enhance operational resiliency for the jail and surrounding county facilities.
Technology improvements also remain a priority. We are actively pursuing grant opportunities to replace our aging body-worn camera system. While the current equipment has served us well, it is becoming outdated and will not adequately meet future operational, evidentiary, and transparency needs. Our goal is to equip all field deputies with modern body-worn cameras that improve accountability, strengthen evidence collection, and further enhance public trust in law enforcement.
The Osage County Sheriffโs Office remains committed to identifying opportunities for improvement while being responsible stewards of taxpayer resources. Whether through infrastructure upgrades, technology investments, school safety initiatives, or community service programs, our focus remains on delivering professional and effective public safety services to the citizens of Osage County.
As always, I remain committed to transparency, accountability, and meaningful progress. I am proud of the dedication and professionalism demonstrated every day by the men and women of the Osage County Sheriffโs Office. Their commitment to serving our citizens is what makes these accomplishments possible.
Thank you to the people of Osage County for your continued trust, support, and partnership as we work together to keep our communities safe.
