Eastern Washington is the region of the U.S. state of Washington located east of the Cascade Range. It contains the city of Spokane (the second largest city in the state), the Tri-Cities, the Columbia River and the Grand Coulee Dam, the Hanford Nuclear Reservation and the fertile farmlands of the Yakima Valley and the Palouse. Unlike in Western Washington, the climate is dry, including some desert environments.

Köppen climate types in eastern Washington

A significant difference between Eastern Washington and the western half of the state is its climate. While the west half of the state is located in a rainy oceanic climate, the eastern half receives little rainfall due to the rainshadow created by the Cascade Mountains. Also, due to being farther from the sea, the east side has both hotter summers and colder winters than the west. Most communities in Eastern Washington, for example, have significant yearly snowfall, while in the west snowfall is minimal and not seen every year. The east and west do still have some climatic traits in common, though: more rainfall in winter than summer, a lack of severe storms, and milder temperature ranges than more inland locations.

There is some variation in both temperature and rainfall throughout Eastern Washington. Generally, lower elevations are both hotter and drier than higher elevations. This is easily seen in the comparison between low-elevation Richland with higher elevation Spokane.

  Liberty

There have been sporadic movements to create a 51st state out of Eastern Washington by splitting the current state down the Cascades, but proposals have rarely progressed out of the state legislature's committees. Bills in the Washington State Legislature which would have requested the United States Congress to take up the question were proposed in 1996, 1999, 2005, and 2017. [12] Proposed names for the new state have included Lincoln, Columbia, Liberty, [13] or simply Eastern Washington. Many of these proposals would include the Idaho Panhandle as part of the proposed state of Lincoln.

Eastern Washington tends to vote Republican, whereas Western Washington usually votes Democratic. However, Spokane, the proposed capital and largest city, tends to have a higher democratic vote than other Eastern Washington cities. Additionally, Whitman County votes Democratic.

<span class="mw-page-title-main">Washington wine</span> Wine produced from grape varieties grown in the U.S. state of Washington

Washington wine is a wine produced from grape varieties grown in the U.S. state of Washington. Washington ranks second in the United States in the production of wine. By 2017, the state had over 55,000 acres (220 km2) of vineyards, a harvest of 229,000 short tons (208,000 t) of grapes, and exports going to over 40 countries around the world from the 940+ wineries located in the state. While there are some viticultural activities in the cooler, wetter western half of the state, the majority (99.9%) of wine grape production takes place in the shrub-steppe eastern half. The rain shadow of the Cascade Range leaves the Columbia River Basin with around 8 inches (200 mm) of annual rain fall, making irrigation and water rights of paramount interest to the Washington wine industry. Viticulture in the state is also influenced by long sunlight hours and consistent temperatures.

<span class="mw-page-title-main">Columbia Valley AVA</span>

The Columbia Valley AVA is an American Viticultural Area which lies in the Columbia River Plateau, through much of central and southern Washington State, with a small section crossing into the neighboring state of Oregon. The AVA includes the drainage basin of the Columbia River and its tributaries through much of Washington. Allen Shoup, president of Washington State's largest winery Chateau Ste. Michelle, understood the importance of obtaining appellation status for Washington State to grow the reputation of the vineyards. He hired Drs. Wade Wolfe and Walter Clore to petition the federal government for appellation status, a request that was granted in 1984. The Columbia Valley AVA is the largest wine region in the state of Washington, including over 11,000,000 acres (4,500,000 ha), of which over 50,000 acres (20,000 ha) are planted in vineyards. The Columbia Valley AVA includes 99% of the total vineyard area planted in the state of Washington. Grapes grown here include Cabernet Sauvignon, Merlot, Chardonnay, Riesling, Syrah, Pinot Gris, and Sauvignon blanc. Concord grapes and other Vitis labrusca grapes are grown in the region as well. The unique climates of the area allow the Columbia Valley to produce wines that are very fruit-forward, like California wine, but which also retain some of the balance and structure of European wine.

<span class="mw-page-title-main">Washington (state)</span> U.S. state

Washington, officially the State of Washington, is a state in the Pacific Northwest region of the Western United States. Named for George Washington—the first U.S. president—the state was formed from the western part of the Washington Territory, which was ceded by the British Empire in 1846, by the Oregon Treaty in the settlement of the Oregon boundary dispute. The state is bordered on the west by the Pacific Ocean, Oregon to the south, Idaho to the east, and the Canadian province of British Columbia to the north. It was admitted to the Union as the 42nd state in 1889. Olympia is the state capital. The state's most populous city is Seattle.

<span class="mw-page-title-main">Geography of Washington (state)</span> Overview of the Geography of Washington

Washington is the northwesternmost state of the contiguous United States. It borders Idaho to the east, bounded mostly by the meridian running north from the confluence of the Snake River and Clearwater River, except for the southernmost section where the border follows the Snake River. Oregon is to the south, with the Columbia River forming the western part and the 46th parallel forming the eastern part of the Oregon–Washington border. During Washington's partition from Oregon, the original plan for the border followed the Columbia River east until the confluence with the Snake, and then would have followed the Snake River east; this was changed to keep Walla Walla's fertile farmland in Washington.

The 2021 Washington wildfire season officially began in March 2021. By late April, all of Eastern Washington had been classified by the United States Drought Monitor as "abnormally dry" with moderate to severe drought conditions. The state had more than 630 wildfires by the first week of July, on par with the state's record 2015 wildfire season.
