[1] The resort was founded in 1959 by Joseph Mazzola, president of United Association Local 38, a union of Northern California plumbers.
The court also appointed WhiteStar Advisors LLC as a second fiduciary to oversee the management and operation of Konocti Harbor, as well as the pending sale to Page Mill Properties [9] (which later fell through).
[6] In late 2009 WhiteStar Advisors, the management company that had been hired by the court, announced that Konocti Harbor would be shut down "temporarily but indefinitely".
[14] The company plans to reopen the resort and make significant upgrades, including a "small waterside bar and grill at the northern terminus of the promenade, improving the functionality of the clubhouse with a port cochere and arrival court as well as creating new indoor/outdoor public spaces at the lakeside, expanding the number of concert parking spaces located onsite, and concentrating them in closer proximity to the amphitheater, relocating the boat yard building for repair and storage of watercraft away from the shoreline to a less strategic location on the property, improving the amphitheater facility with structural repairs where needed, new concession stands and landscaping, bringing the existing resort buildings into compliance with current ADA, life safety, seismic resistance and energy conservation codes, upgrading the landscaping, fountains, entrance gates and other site improvements (driveways, sidewalks, curbs, retaining walls, lighting and signage) to contemporary standards and creating a small vineyard and wine tasting pavilion on the site of an existing parking lot."
[16] The resort held a soft-opening in April 2023, with an operational 124-room hotel, marina and Andy's Tavern restaurant, but no immediate plans to reopen the outdoor amphitheater.
