Legend says that the name "Richvale" (meaning "fertile valley") was coined by con men to sell worthless plots of land to wheat farmers from Nebraska and Kansas. The developers (Richvale Land Company) changed the name from Selby Switch (a railroad siding) to Richvale in 1909. The place was settled in 1911, and a post office opened that same year.
Farmers in the Midwest were shown lush pictures of California's Sacramento Valley and San Joaquin Valley and sold land at outrageous prices. The soil near Richvale is nothing like the fertile soil of the San Joaquin Valley, being composed mostly of clay instead of loam. The dominant soil is Esquon clay, a poorly drained vertisol.[3] [4] The locals call the soil "adobe" due to its high clay content. The land is unsuitable for vineyards, orchards, and most other crops. Some buyers took one look at the soil and returned to the Midwest. Those who stayed built a community from the muddy ground up: a post office (1912), roads, an irrigation and drainage district, a hotel (1913), a church (1913), a cooperative (1914 and still operating, the Butte County Rice Growers Association), a school (1914), and a grocery store (1920). During a second wave of migration Dust Bowl farmers came west during the Great Depression.
Due to the adobe soil's ability to retain water and remain flooded, the ground makes a near-ideal rice paddy, and rice has become the primary crop of the area. Irrigation is provided by plentiful surface water from the Feather River.
In 2005, 33500acres of rice were served by the Butte County Rice Growers Association. Current storage capacity is 3200000short cwt. With time and a lot of hard work, the town of Richvale lived up to its name as rice farming provided an abundant livelihood for the original settlers and their offspring.
The history of Richvale was recently written by the Richvale Writing Group (with Teresa Ward) and published by The Community Foundation of Richvale in a book (Richvale: A Legacy of Courage, Dedication, and Perseverance) with 364 historical photographs.
