Buhl is a city located on the old Oregon Trail in the western half of Twin Falls County, Idaho, United States.
Historic U.S. Route 30 goes right through Buhl along the scenic Thousand Springs Scenic Byway from Twin Falls to Bliss. Known as the "Trout Capital of the World," Buhl boasts numerous hatcheries in the immediate surrounding area, which produce most of the rainbow trout consumed in the United States. Clear Springs Foods, located just north of Buhl, processes over 20 million pounds of rainbow trout each year, making it the world's largest producer.
Buhl was founded on April 17, 1906. It was named for Frank H. Buhl, a major investor in a Carey Act project known as the Twin Falls South Side project, which introduced large-scale irrigation to the region in the early 20th Century.
