New Casino Coming to Sonoma County, CA

A new casino resort, named Caesars Republic Sonoma County, will open in Geyserville in the summer of 2027. The Dry Creek Rancheria Band of Pomo Indians has partnered with Caesars Entertainment on a major construction project to transform the River Rock Casino into a destination casino with 1,000 slot machines and 28 table games plus a 100-room hotel with a luxury spa, pool and fitness center.

The ground-breaking ceremony was held Aug. 2 at River Rock Casino. Several speakers commemorated the event with the following comments:

"Breaking ground on Caesars Republic Sonoma County marks a monumental moment for Dry Creek Rancheria. This partnership with Caesars Entertainment represents more than just a new chapter in our casino's story - it's a bold leap into the future for our Tribe and our community. Together, we are creating a world-class resort experience that blends the natural beauty of Sonoma County with premier gaming, hospitality and entertainment.

"We are proud to work alongside Caesars, Citizens and GLPI to bring this vision to life and elevate our economic and cultural legacy. This project is a powerful step forward and we are eager to share it with the region and beyond."

- Chris Wright, Chairman Dry Creek Rancheria

"On the heels of a successful launch of Caesars Republic in Lake Tahoe, we couldn't think of a better place than Sonoma County to continue the brand's expansion.

"We're excited to partner with Dry Creek Rancheria to bring this incredible destination to life and offer a new, elevated and unique experience for our guests to indulge in, right in the heart of wine country."

- Anthony Carano, Pres. COO, Caesars Entertainment.

Additional details about the project are expected to be announced later this month when the Geyserville Planning Committee meets to host a public meeting on September 26, 2025 at 6:00 PM. The committee is a community advisory group requesting more information about the project. Dry Creek Rancheria and Caesars Entertainment have been invited to make presentations about the casino transformation, the new hotel plans, community concerns, economic effects and regional impacts.

River Rock Casino will continue to operate during the two-year construction of the Caesars Republic Sonoma County. The casino is located off Hwy 101 and sits above the Alexander Valley with views of vineyards and the Russian River.

River Rock Casino will transform into Caesars Republic Sonoma County

Dry Creek Rancheria and Caesars Entertainment have partnered to transform the River Rock Casino into a new resort to be named Caesars Republic Sonoma County. A groundbreaking event was held Aug. 2 to begin construction on the two-year project which will open in Summer 2027.

River Rock Casino is owned by the Dry Creek Rancheria and currently operates inside a tent-like structure. There are 1,000 slot machines, 11 table games, and three dining venues. For the past few years, the tribe has been planning to expand into a permanent casino and add a hotel to attract overnight guests. A tentative plan was announced in early 2023.

That plan eventually evolved into the new partnership with Caesars Entertainment to build the Caesars Republic Sonoma County. Caesars is involved with the development and will manage the property when it opens in 2027.

The new casino will be a luxury resort with a casino featuring 1,000 slot machines and 28 table games, a 100-room hotel, and three restaurants. It will also feature a wine bar with views of Alexander Valley.
