Idaho is known for its potatoes, but it wasn't until the 1930s that potatoes became a major crop in the state. Before that, wheat was the primary crop grown in Idaho.
Power County, Idaho has a rich history that dates back thousands of years. The area that is now Power County was originally inhabited by the Shoshone and Bannock Native American tribes, who lived off the land and used the nearby Snake River for fishing and transportation. The arrival of European settlers in the 19th century brought significant changes to the region.

In the mid-1800s, Mormon pioneers settled in the area, establishing the town of American Falls in 1804. The pioneers were attracted to the fertile soil and the abundant water supply from the Snake River, which allowed for successful agricultural ventures. The town quickly grew as more settlers arrived, and by the late 1800s, it became a thriving agricultural community.

The development of the Oregon Short Line Railroad in the late 19th century further stimulated growth in Power County. The railroad connected American Falls to other major cities, facilitating trade and opening up new opportunities for local businesses. The arrival of the railroad led to the establishment of several industries in the county, including processing plants and factories.

The construction of American Falls Dam in the early 20th century brought a new era of prosperity to Power County. Completed in 1927, the dam provided hydroelectric power, irrigation water, and flood control for the region. The reservoir created by the dam, aptly named American Falls Reservoir, became a popular destination for recreation, attracting tourists and boosting the local economy. Today, Power County continues to thrive, with a diverse economy that includes agriculture, manufacturing, and tourism.
