Little Panoche Creek  Little Panoche Creek formerly known as Arroyita de Panoche or Arroyo de Pannochita  (Little Sugarloaf Creek) and later anglicized to Panochita Creek is a creek in Fresno County, California. The source of this creek is on the east slope of Glaucophane Ridge, of the Diablo Range in San Benito County. It flows east-northeast through Little Panoche Reservoir to empty into the California Aqueduct. Before the advent of irrigation projects in the valley, its waters might have reached a slough of the San Joaquin River in years of heavy rains. Arroyita de Panoche was a watering place on El Camino Viejo in the San Joaquin Valley between Arroyo de Las Ortigalito (Little Nettle Creek) and Arroyo de Panoche Grande (Big Sugarloaf Creek).
