Lewis-Clark Valley is Idaho's third American Viticultural Areas (AVA) officially established by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury on May 20, 2016. It borders the northern part of the established Columbia Valley AVA. The region encompasses 479 square miles (306,560 acres) with nearly 100 acres (40 ha) under vine throughout the Lewis-Clark Valley between the Clearwater and mid-Snake Rivers and their tributaries. About 72%, 219,838 acres (343.497 sq mi), is located in Idaho with the rest in Washington. The topography consists primarily of deep, V-notched canyons, low plateaus, and bench lands formed by the two rivers. There were 3 wineries within the appellation, as well as 16 commercially-producing vineyards with elevations approximately below 2,000 feet (610 m). Lewis-Clark Valley boundaries forced the realignment of the existing Columbia Valley viticultural area by expanding into its area based on topography, climate and soil conditions. The realignment more accurately separated the terroir differences between the two appellations. Roughly about 72% (219,838 acres (88,965 ha)) of Lewis-Clark Valley is located in Idaho and the rest in Washington.
