The project was put into operation in 1972 and has facilitated the navigation of billions of dollars\u2019 worth cargo annually. The lock portion of the project is located on the Ohio side of the river. There are two locks at Willow Island, one main lock which is 1,200 feet in length, and an auxiliary lock that is 600 feet in length. The gated dam is 1,017 feet long and is operated by eight steel tainter gates. These gates allow the pool behind the dam to be maintained at the proper level for navigation along the Ohio River. A commercial hydropower facility was completed in 2016 on the West Virginia side of the Locks and Dam. The plant includes two turbines with a total capacity of 35,000 kilowatts.", "riskCharSummary":"Navigation Locks and Dams such as Willow Island do not provide any protection from flooding. Willow Island Locks and Dam purpose is to manage the pool elevation upstream and to permit navigation through the river. The dam cannot perform any flood risk reduction measures. Because of this, the projected life loss from failure of the dam is zero. There would however be large economic consequences if Willow Island Locks and Dam lost pool. The loss of navigation along the Ohio would devastate local industry. The loss of pool would also cause major slippage of the riverbank along the Ohio and it\u2019s large tributaries between Willow Island Locks and Dam and Hannibal Locks and Dam upstream. This streambank erosion would cause roads and structures along the bank to be in jeopardy of slipping into the river.", "riskManagementMeasures":"Routine operations and maintenance of the project is ongoing.
