Discover the fascinating engineering behind the Oroville Dam, the tallest dam in the United States! In this video, we explore the history, construction, and operation of this multipurpose project, which provides water storage, hydroelectric power generation, flood control, and recreation opportunities. Learn about the natural resources used in building and maintaining the dam, including water, concrete, steel, and more. Discover the challenges and lessons learned from the 2017 spillway damage and repair project. Join us on this journey to explore the Oroville Dam's importance, safety, and environmental conservation effort. The largest dam in the United States by volume is the Oroville Dam, located in Northern California. In 2017, heavy rainfall caused damage to the dam's spillway, leading to concerns about the dam's safety and the potential for flooding downstream. Over 180,000 people were evacuated from their homes as a precautionary measure. The damaged spillway was eventually repaired, and the dam was deemed safe. The Oroville Dam is a concrete gravity dam on the Feather River in Butte County, California. It was completed in 1968 by the California Department of Water Resources and stands at a height of 770 feet, making it the tallest dam in the United States. The Oroville dam is used for water storage, hydroelectric power generation, flood control, and recreation. The dam has a total capacity of 4.3 billion cubic meters of water, which is enough to supply the needs of more than 20 million people for a year. The hydroelectric power plant at the base of the dam has a capacity of 819 megawatts.
In February 2017, heavy rainfall caused significant damage to the Oroville Dam's main spillway, a concrete channel that releases water from the dam during high water events. The spillway began to erode and a large crater formed in the concrete, which led to concerns about the safety of the dam and the potential for a catastrophic failure. As water continued to flow into the reservoir, of the Oroville Dam, management authority used the emergency spillway, a backup structure that had never been used before, to release water. However, water flowed over the emergency spillway and eroded the hillside beneath it, threatening to undermine the spillway's foundation and potentially cause a collapse of the entire structure. As a result, over 180,000 people downstream of the Oroville Dam were evacuated from their homes as a precautionary measure. Engineers and workers rushed to repair the damaged spillway and reinforce the emergency spillway to prevent a catastrophic failure. The repairs were completed before the next rainy season, and the dam was deemed safe. The budget for the Oroville Dam project includes the costs associated with the construction, operation, maintenance, and repair of the dam and its associated facilities. The original construction cost of the dam was approximately $1.2 billion when it was completed in 1968, which would be approximately $9.2 billion in today's dollars, adjusting for inflation. The operation and maintenance of the Oroville dam are ongoing costs that are funded by the California Department of Water Resources. The department operates the dam and manages the water resources in the Feather River watershed, including the storage and distribution of water from the Oroville Reservoir. The cost of repairing the damage to the Oroville Dam spillway in 2017 was estimated to be over $1 billion. The repair project was funded by a combination of state and federal funds, including emergency funding from the Federal Emergency Management Agency. The Oroville Dam incident highlighted the importance of infrastructure maintenance and the potential risks of aging dams and other critical. The Oroville Dam is a multipurpose project that provides a range of benefits and uses several natural resources. Overall, the budget for the Oroville Dam project includes ongoing operational and maintenance costs, as well as occasional large scale repair or improvement projects, which are funded by a combination of state and federal resources.
