Tres Rios Golf Course at Estrella Mountain Regional Park will  close temporarily starting Monday, Aug. 17, according to a release.

The closure comes after the current operator, Tres Rios Golf LLC., a division of C-Bon International Golf Group, served notice to Maricopa County on July 6 it wanted to terminate the contract, the release states.

The 180-day termination clause in the contract would have meant a closure date in mid-December. As the operator since 2012, the terms of their current contract run through April 30, 2037.

Last week, CBIGG notified the county that it was planning to close Tres Rios Golf Course effective Monday, Aug. 17. CBIGG has cited an ongoing loss of revenue as the reason for its desire to terminate the lease, according to the release. Throughout the past month, the county and CBIGG have informally sought interest from viable golf course operators to take over without success.

The county will now begin a formal process to seek interested parties for a new management agreement.

During the past several years, many golf courses around the Valley have been financially strained, and Tres Rios Golf Course is no exception, the release states. CBIGG has kept the county informed about its difficulty generating enough income, despite efforts to market the property.

CBIGG has agreed to provide a minimal level of maintenance over the next three months to maintain the integrity of the turf for a future operator, the release states.

Although Tres Rios Golf Course will be closed, Maricopa County's two other golf courses, The 500 Club and Paradise Valley Golf Course, remain open to the public.

"Tres Rios on Monday the 17th will be closing the doors for golf indefinitely," CBIGG states on the golf course's website. "The golf course will be maintained until the Maricopa County Parks and Recreation can decide on any future interested parties. Tres Rios thanks all the local and supportive players and groups that have visited with us over the years and we wish you continued success in your future golfing endeavors."

According to its website, Tres Rios Golf Course originally was designed by course architect Red Lawrence. It first opened in 1962 and was renovated in 1998.
