Exhibit 99.1

River Rock Entertainment Authority Amends its 9¾% Senior Notes Due 2011

Geyserville, CA. December 14, 2011—River Rock Entertainment Authority (the “Authority”), a governmental instrumentality of the Dry Creek Rancheria Band of Pomo Indians, a federally recognized tribe (the “Tribe”) and the operator of the River Rock Casino in Sonoma County, California, announced today that, following approval by holders representing over 95% of the 9¾% Senior Notes due 2011 (the “Existing Notes”) outstanding, the previously-announced amendments to the indenture and collateral documents governing the Existing Notes became effective as of 12:00 Midnight (New York City time) on December 13, 2011 (the “Withdrawal Deadline”).

To implement the amendments, the Authority, the Tribe and U.S. Bank National Association, as trustee (the “Trustee”), have entered into a First Supplemental Indenture to the indenture, dated as of November 7, 2003, governing the Existing Notes (the “Indenture”) and agreements amending the Pledge and Security Agreement, dated as of November 7, 2003, among the Tribe, the Authority and the Trustee and the Deposit Account Control Agreement, dated January 11, 2010, among the Tribe, the Authority, the Trustee and Bank of the West.  In addition, the Cash Collateral and Disbursement Agreement, dated as of November 7, 2003 and amended as of November 17, 2003, among the Tribe, the Authority, the Trustee and the other parties thereto has been terminated.

The amendments and termination will become operative on the date the Authority pays the exchange consideration and the consent consideration for Existing Notes accepted for exchange and corresponding consents delivered pursuant to the Authority’s offer and consent solicitation to tendering holders (the “Exchange Date”).  The Authority expects the Exchange Date to occur on December 21, 2011.  As the First Supplemental Indenture has become effective and the Withdrawal Deadline has now occurred, Existing Notes tendered and corresponding consents delivered prior to December 13, 2011 may no longer be withdrawn or revoked.

The amendments remove substantially all protective covenants and events of default from the Indenture (other than those relating to payment of principal and interest) and subordinate the liens on the Authority’s assets securing the Existing Notes to the liens that will secure the new 9% Series A Senior Notes due 2018 and new 8% tax-exempt Series B Senior Notes due 2018 (collectively, the “New Notes”) to be issued by the Authority on the Exchange Date.  Existing Notes that are not tendered and accepted for exchange will thereupon become subject to the amendments and the rights of the holders of New Notes.

Holders who have not yet tendered their Existing Notes and delivered their consents may do so at any time on or prior to 12:00 Midnight (New York City time) on December 19, 2011 (the “Expiration Date”).  Holders who tender New Notes and deliver corresponding consents after the Withdrawal Deadline and on or prior to the Expiration Date will be eligible to receive the exchange consideration and the consent payment, but not the consent premium.  Existing Notes tendered and corresponding consents delivered after the Withdrawal Deadline may not be withdrawn or revoked.

The Authority’s offer and consent solicitation is being made pursuant to Section 3(a)(9) of the Securities Act of 1933, as amended. This press release is not an offer to exchange any Existing Notes, a solicitation of an offer to exchange any Existing Notes, a solicitation of consents with respect to the Existing Notes, an offer to sell any of the New Notes or the solicitation of an offer to buy any New Notes.  The offer and consent solicitation is being made solely pursuant to an offering circular and consent solicitation statement and a related letter of transmittal and consent (collectively and, together with any amendment thereto, the “Offer Documents”), which have been furnished to the holders of the Existing Notes.  The Offer Documents set forth the complete terms of the offer and consent solicitation.  The Offer Documents contain forward-looking statements and include cautionary statements identifying important factors that could cause actual results to differ materially from those anticipated.
