The Oroville Dam is a large earthfill dam located on the Feather River in Oroville, California. Completed in 1968, it is the tallest dam in the United States, standing at 770 feet. The dam serves multiple purposes, including flood control, water supply, and hydroelectric power generation. The reservoir created by the dam, known as Lake Oroville, is a popular recreational area for boating, fishing, and camping. The dam is operated by the California Department of Water Resources and plays a crucial role in the state's water management system, particularly during drought conditions.
