TheTreasure Valley is avalley in thewestern United States, primarily insouthwestern Idaho, where thePayette,Boise,Weiser,Malheur, andOwyhee rivers drain into theSnake River. It includes all the lowland areas fromVale in ruraleastern Oregon toBoise, and is the most populated area in Idaho.
Historically, the valley had been known as the Lower Snake River Valley or the Boise River Valley. Pete Olesen, president of the valley's association of local Chambers of Commerce, coined the name "Treasure Valley" in 1959 to reflect the treasure chest of resources and opportunities that the region offered. The valley has a very diverse terrain, from sage flatlands, to mesas, agricultural areas, and urbanized areas. As the Boise Metropolitan Area grows, more and more undeveloped and agricultural land is being urbanized.
The tribes that roamed the area, specifically, were theNorthern Paiute andShoshone.[1] In 1834,Thomas McKay built the originalFort Boise, in the area near present-dayParma, which was run for a time byFrancois Payette. It later was moved because of flooding troubles and was abandoned in 1854. TheOregon Trail runs through the Treasure Valley.
The valley was settled for the most part by ranchers and farmers, initially to supply thegold andsilver mining communities in the higher elevations nearby:Idaho City in theBoise Basin andSilver City in theOwyhees. A new Fort Boise was constructed by theU.S. Army in 1863 in present-day Boise, from which the city grew. In 1883, theOregon Short Line Railroad reached the Treasure Valley, creating a thriving community, withNampa as the center of the area's rail activity.
ManyBasques, primarily from northernSpain, came to the area looking for gold but, meeting discrimination, it seemed to many that a better occupation was shepherding, familiar from their homeland. Over 15,000 Basques came to the Treasure Valley, making it the largest community of Basques outside of Europe.[2][3]
As Boise began to grow, so did the riches of large planters such as Thomas and Frank Davis. They moved to Idaho in 1862 for mining andhomesteaded right below the Boise Bench on theBoise River. Tom Davis became very successful at growing fruit, as he made over $10,000 on one year's apple crop.[4] He later purchased more land for orchards and horses. In 1907, he donated much of this land asJulia Davis Park in honor of his wife.
The Owyhee Project was one of the most influential developments of the area. It began 122 years ago in 1903, when surveyors began investigating a site on theOwyhee River for the construction of a dam, to impound water for irrigation. The Owyhee project received official Congressional sanction in 1924 on December 5 and theOwyhee Dam was completed on September 16, 1932.[5] While the dam was under construction, over 98.5 miles (159 km) of irrigation canals were being dug to the north and south. The main purpose of the Owyhee Project was irrigation. By 1965, over 111,000 acres (450 km2) were being irrigated for a value of more than $23 million.
In 1941,J. R. Simplot built a dehydrator and began processing large quantities of dehydrated potatoes and onions at a plant nearCaldwell.[6] His business thrived, selling potatoes to the government and fertilizer to local farmers.
In 1973,Hewlett-Packard purchased a 150-acre (60 ha) site for a future peripherals plant in northwest Boise.[7]Micron Technology was founded in 1978, creating an additional, local industry aside from farming and potato packaging.[8]
