The Lake Norconian Club is a historic former hotel/resort in Norco, California, opened in 1929, sited in a rural community, whose main businesses were poultry, rabbits, and agriculture.

The land was a failed agricultural community known as "Orchard Heights", but Clark renamed this hilly area "Norco", based on its position North of Corona.

In less than three years, Clark's engineer, "Captain" Cuthbert Gulley (April 30, 1878 – 1961) – so named for his service in World War I – laid out streets and installed pumps and reservoirs and on May 13, 1923, "Norco" held its grand opening.

[3][4] In 1925, Gulley, while drilling a well, struck hot mineral water, giving rise to the idea of a health spa that would ultimately become The Norconian.

Construction of the resort began in 1926, and consisted of a golf course, grounds, airfield, hiking trails, Lake Norconian pavilion, chauffeurs' quarters, garage, powerhouse, laundry, and a "clubhouse", which consisted of a first class hotel, two indoor bath complexes, ornate ballroom, dining room and lounge, and the first outdoor Amateur Athletic Union-qualifying swimming and diving pools in Southern California.

In 1933, noted aviator Marshall S. Boggs, who piloted the first "blind" landing entirely using radio signals in 1931, crashed and was killed while making a routine approach to the airfield.

The outdoor diving and swimming pools were in constant use for exhibition matches and AAU-sanctioned competitions, and many Olympic-caliber athletes swam and dove there, including Mickey Riley, Buster Crabbe, Esther Williams, Sammy Lee, Dorothy Poynton, Georgia Coleman, Duke Kahanamoku, Arne Borg and many others.

Norma Talmadge's first "talkie", New York Nights, premiered in nearby Corona, with dozens of Hollywood stars in attendance.

Almost immediately, the Navy held up payment, and Rex Clark spent four long years in court fighting for the $2,000,000 promised by the federal government.

Actress Kay Francis was in charge of hospital morale, and she saw to it that many of the stars who frequented the resort now entertained the patients, including The Three Stooges, the Marx Brothers, Abbott and Costello, James Cagney and Clark Gable.

This voluntary program – those with substance use disorder had a choice of prison or CRC – moved into the old resort clubhouse, the northern wards, north wing, chapel, gymnasium, and nurses quarters.

In 1995, the Navy released a study that concluded that no aspect of the Norconian resort era facilities qualified for National Register of Historic Places listing.

In 2004, a State of California study concluded that the main hotel building was not in compliance with current earthquake construction standards, and it was subsequently abandoned.

Today, this 250,000 square foot Spanish Colonial Revival building sits behind twenty-foot-high chain link and concertina wire fences, crumbling from neglect.
