Prosser

Prosser is a town in Benton County in eastern Washington, situated along the Yakima River and surrounded by vineyards and farmland. The area has become an important center for wine production and agriculture.

Colonel William Farrand Prosser established a homestead in 1882, which led to the town's establishment in 1893. These early years formed the foundation for development into an agricultural community.

The town is known for its annual Wine and Food Fair, which brings together local wineries and restaurants to celebrate regional products. This event reflects how wine production has become central to the community's identity.

The town sits along a river in a region shaped by agricultural activity, which defines movement through the area. Visitors should note that the best time to explore is during the warmer months when harvests are underway and local markets are active.

A research station operated by Washington State University has been located there since 1919, focusing on irrigation techniques and water management. This facility has helped generations of farmers improve their practices.
