The Great Feeder

Jefferson County, Idaho, has a rich and diverse history that dates back thousands of years. The region was originally inhabited by Native American tribes such as the Shoshone and Bannock, who relied on hunting, gathering, and fishing to sustain their communities. Their presence in the area would shape the region's future as European settlers arrived.

The arrival of European explorers and fur trappers in the early 19th century marked a new era for Jefferson County. The Lewis and Clark Expedition, led by Meriwether Lewis and William Clark, passed through the area in 1805, documenting their journey and mapping the land. This opened the door for future settlers and led to increased exploration and settlement in the region.

By the mid-1800s, pioneers began to establish permanent settlements in Jefferson County. The Oregon Trail, a major westward migration route, passed through the area, attracting settlers in search of new opportunities. Over time, farming and ranching became the main economic activities in the region, with communities like Rigby and Menan prospering as agricultural centers.

The 20th century brought significant changes to Jefferson County. The construction of the Minidoka Dam in the 1900s brought irrigation water to the area, transforming dry lands into fertile farmland. The development of transportation infrastructure, such as roads and railways, further connected the county with the rest of the state and facilitated economic growth. Today, Jefferson County retains its agricultural heritage while also benefiting from its proximity to larger cities like Idaho Falls, contributing to the county's ongoing development and prosperity.
