Cat Creek located east of Winnett was the site of Montana's first commercially successful oil strike in 1920. A pipeline was built to the railroad at Winnett. By 1975 the oil boom had diminished. It has been estimated that about 23 million barrels of oil have been produced in Cat Creek's 54-year history. Dryland farming and cattle ranching were main occupations of Cat Creek since its founding.
