Everything about Sacramento Valley totally explained
» For the Arizona valley, see Sacramento Valley (Arizona)
The
Sacramento Valley is the portion of the
California Central Valley that lies to the north of the
San Joaquin-Sacramento Delta in the
U.S. state of
California. It encompasses all or parts of ten counties.
Geography
The
Sacramento River and its tributaries dominate the geography of the Sacramento Valley. Rising in the various mountain ranges (the various
Northern Coast Ranges to the west, the southern
Siskiyou Mountains to the north, and the northern
Sierra Nevada to the east) that define the shape of the valley, they provide water for agricultural, industrial, residential, and recreation uses. Most of the rivers are heavily dammed and diverted.
The terrain of the Sacramento Valley is primarily flat
grasslands that become lusher as one moves east from the
rain shadow of the Coast Ranges toward the Sierras. Unlike the San Joaquin Valley, which in its pre-irrigation state was a vegetation-hostile desert, the somewhat less arid Sacramento Valley had significant tracts of forest prior to the arrival of settlers of European ancestry. Most of it was cut down during the
California Gold Rush and the ensuing wave of white American settlement.
Foothills become a lot more common from just south of
Corning to
Shasta Lake City. These are known as the Valley Hills. The start of the valley hills is just south of Rolling Hills Casino at the Tehama-Glenn County line near Corning. There are also a few hills in Red Bluff and Corning. There is one major range of foothills between Cottonwood and Red Bluff known as the Cottonwood Hills (a.k.a 9 Mile Hill), and there's the Cottonwood Ridge between Anderson and Cottonwood. There are some hills in Redding, a few more than Red Bluff, and after Redding it's mainly foothills.
One distinctive geographic feature of the Sacramento Valley are the
Sutter Buttes. Nicknamed the smallest mountain range in the world, it consists of the remnants of an extinct
volcano and is located just outside of
Yuba City.
Agriculture
Citrus and
nut orchards and
cattle ranches are common to both halves of the Central Valley. The Sacramento Valley's agricultural mix also resembles that of the
San Joaquin Valley to the south. Nuts (primarily
almonds and
walnuts) are of greater importance north of the Delta, and
rice, which is unviable in the bone-dry deserts of the San Joaquin, is a major crop. The town of
Corning proclaims itself "
Olive City," producing olives for oil extraction and for consumption as fruit. In the central Sacramento valley lies the
Sunsweet Growers Incorporated headquarters in
Yuba City where more than half the growers in California belong to Sunsweet. The valley controls more than two-thirds of the worldwide prune market through the over 400 growers in California.

Climate
Weather patterns in the Sacramento Valley are very similar to those in San Joaquin Valley to the south, although the humidity and precipitation tends to be a bit higher, especially in winter and spring. Summers are generally very warm and dry with average daytime temperatures usually around the low 90s, but triple digits are a common occurrence, especially in the
Redding and
Red Bluff area. Summerlike weather often continues well into fall; foliage usually doesn't begin until mid- to late-October. Winters are generally mild and wet with highs averaging in the mid-40s to low-50s, colder in the northern part of the valley and colder still in the foothills. During the rainy season, the Sacramento Valley is prone to relatively strong thunderstorms and, perhaps surprisingly, a fair number of
tornados (albeit mostly of F0 or F1 intensity), especially in
Colusa County and areas around Corning and Orland. Snow in the valley is rare, although
Redding and
Red Bluff, being at the north end of the valley, often experience a light dusting or two per year.
Chico may get a rain-snow mix every few years, but it won't actually snow for about every 5 years. Farther south in Sacramento, snow falls about once every 10 years or so.. During the winter months, the entire Central Valley is susceptible to dense
tule fog that makes driving hazardous, especially at night and especially south of Corning.
Transportation
Interstate 5 is the primary route through the Sacramento Valley, traveling lengthwise roughly at the valley's center.
Interstate 80 cuts a northeast-to-southwest swath through the southern end of the valley, mostly through Sacramento and Yolo Counties. Several secondary routes connect the two roads, including
Interstate 505 and
State Route 113. The Sacramento area has a web of urban freeways.
Other principal routes in the region include
State Route 99, which runs along the valley's eastern edge, roughly parallel to I-5, from Sacramento until its northern
terminus in
Red Bluff;
State Route 20, which traverses the valley from west to east on its route from
State Route 1 in
Mendocino County to the
Donner Pass;
State Route 49, named in honor of the
California Gold Rush and running through many old mining towns in the foothills of the valley; and
State Route 45, which runs along the course of the Sacramento River roughly ten miles (20 km) east of I-5.
The
Union Pacific Railroad serves the valley, with its principal north-south line from
Oakland to
Portland, Oregon, via
Sacramento,
Marysville,
Chico, and Redding. This is also the route of
Amtrak's
Coast Starlight passenger train. The Union Pacific also has two east-west lines, through
Donner Pass (the former
Central Pacific Railroad), and through the
Feather River gorge (the former
Western Pacific Railroad). Amtrak's
California Zephyr uses the Donner Pass route. The
BNSF Railway has a line from
Klamath Falls, Oregon, to a junction with the Union Pacific Feather River line at
Keddie. The BNSF has
trackage rights on both the UP east-west routes. In addition, the
California Northern Railroad operates the former
Southern Pacific Railroad line on the west side of the valley from
Davis to
Tehama (near Red Bluff).
