The Dry Creek Rancheria spent more than two decades running River Rock out of a tent. Now it is keeping the casino but renting the Caesars name, a different way to play California’s building boom.
- The Dry Creek Rancheria Band of Pomo Indians broke ground in August 2025 on Caesars Republic Sonoma County, a $300 million resort replacing its River Rock Casino in Geyserville, with an opening targeted for summer 2027.
- Unlike tribes building under their own names, Dry Creek keeps ownership while bringing in Caesars Entertainment as its development and management partner and plugging into the Caesars Rewards network of more than 50 properties.
- The resort will feature a casino floor with more than 1,000 slot machines and 28 table games, a 100-room hotel with a spa and pool, and a wine bar overlooking the Alexander Valley vineyards.
- Citizens led the financing and Gaming and Leisure Properties signed on as the lead real estate partner, and the property becomes the third Caesars Republic location after Scottsdale and Lake Tahoe.
- The same tribe is also a blocker: Dry Creek joined two neighboring tribes in a federal lawsuit challenging the Koi Nation’s nearby Windsor casino.
GEYSERVILLE, Calif. – For more than 20 years, one of Sonoma County’s casinos has run out of what amounts to a very large tent. The Dry Creek Rancheria Band of Pomo Indians opened River Rock Casino on a Geyserville hillside in 2002, two years after California voters amended California gambling laws to allow casinos on tribal land. A tent-style structure is still where its slot machines hum today. That is about to change in a way no other California tribe has tried in quite the same fashion. Dry Creek is taking down the tent and putting up a $300 million resort, and it is borrowing a famous name to do it. When the doors open in 2027, the sign will not read River Rock. It will read Caesars.
A Tribe That Kept the Casino but Rented the Name
The deal makes Caesars Republic Sonoma County one of the more unusual projects in California’s casino boom. Most of the tribes behind the California tribal casinos expanding right now are building bigger under their own flags. Dry Creek is doing something different. It stays the owner of the casino on its 75-acre rancheria, but it brought in Caesars Entertainment as the resort’s development and management partner. In exchange, the property joins Caesars Rewards, the loyalty program whose members earn and redeem credits at more than 50 Caesars destinations around the country. For a tribe of roughly 1,300 members going up against giants like nearby Graton, that network is the real prize, a marketing pipeline into a national customer base it could never build alone. Citizens led the financing, and Gaming and Leisure Properties came on as the lead real estate partner.
What Is Being Built
The makeover is total. Per Caesars and the tribe, the new resort will carry more than 1,000 slot machines and 28 table games on a fresh casino floor, plus a 100-room hotel with a luxury spa, pool and fitness center. The food and drink list leans hard into the address: a steakhouse, an upscale café, an Asian restaurant and quick-service options, plus a fireside bar, a sports bar and a dedicated wine bar with an outdoor deck looking over the Alexander Valley vineyards and the Russian River. River Rock will keep running until the new building is finished, and the old tent comes down once the operation moves over.
Why Caesars Wants Wine Country
For Caesars, the draw is the setting. The Caesars Republic brand, launched in 2019, is built to take on the character of each location rather than stamp one Las Vegas template everywhere it lands. Dropping a Republic resort into the middle of Sonoma County wine country gives the company a destination it can sell to the affluent travelers already arriving for tastings and tours. President Anthony Carano cast it as a natural next step after the brand’s Lake Tahoe launch, a chance to bring an elevated experience “right in the heart of wine country.” Sonoma County becomes the third Caesars Republic, after Scottsdale and the recently opened Lake Tahoe property. For now the company says it has no plans for live entertainment at the site, positioning it as a gaming and hospitality stop rather than a concert venue.
A Builder and a Blocker at the Same Time
The Caesars deal also captures the two-sided nature of the boom. Even as Dry Creek spends to grow its own casino, it is working to keep a competitor out. The tribe joined the Lytton Rancheria and the Cloverdale Rancheria in a federal lawsuit challenging the approval of the Koi Nation’s planned casino near Windsor, a short drive down Highway 101. The objection is the one that runs through every California gaming fight: a new casino nearby threatens an existing tribe’s market. So the Dry Creek story is the boom in miniature. A tribe pours hundreds of millions into a polished new resort while fighting in court to stop the next one from opening down the road.
