HISTORY

Clear Lake is said to have been formed more than 2 million years ago. Mt. Konocti formed gradually through a number of volcanic episodes. Pomo Indians settled the area over 10,000 years before Spanish soldiers arrived in 1821. By the mid 1800s, the area was being settled by pioneers and Europeans. After being part of Mendocino, Colusa, and Napa counties, Lake County was formed on May 20, 1861. The county’s name derives from the many lakes in the area, most prominently Clear Lake.
