The dam is located near Clinton, Pennsylvania, about 36 miles upstream of the confluence of the Allegheny and Monongahela Rivers in Pittsburgh, Pennsylvania. The purpose of the dam is to create a navigation pool from the dam upstream to Allegheny River Lock and Dam 7, which is located near Kittanning, Pennsylvania. The dam consists of a concrete spillway section, which means that the river flows freely over it. The lock provides a lift of about 12 feet, from the pool downstream of the dam (lower pool) to the pool above the dam (upper pool). The lock allows river traffic to travel upstream or downstream of the dam. The lock consists of a rectangular chamber that is 56 feet wide by 360 feet long and formed on each side by concrete walls and steel gates on the upstream and downstream ends. The upper pool created by the dam provides recreation opportunities and water for nearby communities. The dam also provides hydropower at the plant located in line with the dam near the left bank. The combined benefits from shipping materials and goods, hydropower, water supply, and recreation amount to about 1 million dollars annually. There are no means of controlling the flow over the dam and the dam does not provide the nearby communities any protection from flooding.", "riskCharSummary":"The most recent risk assessment of the dam, which was performed in 2021, characterized the risk as very low, because there is no potential for life loss or significant economic damages in the unlikely event that the dam fails. Although the dam holds back water, failure of Allegheny Lock and Dam 6 will not result in the flooding of downstream communities. \n\nIf the upper pool of the dam is released due to a dam failure, river navigation would be halted, resulting in a loss of economic benefits to the region of about 1 million dollars per year. The economic damage would be temporary, until the upper pool could be restored to allow resumption of shipping, hydropower generation, and boat recreation. Although this scenario is possible, the project has performed well for over 90 years without incident or indications that this scenario is occurring. Due to the relatively low height of the dam, which lies entirely within the banks of the Allegheny River, downstream flooding would not be expected if the dam were to fail, and the upper pool was lost.", "riskManagementMeasures":"To ensure we are taking all steps to reduce the risk to the economy, we will continue to work closely with the Coast Guard, the Waterways Association, and the shipping industry to keep them aware of conditions at the dam and changes to lock operations. We conduct emergency exercises with our external partners to improve communication and reactions in the event of an emergency that threatens the dam or that may adversely affect navigation. We regularly update our emergency action plan. We conduct routine monitoring and surveillance of the lock and dam. We closely follow rainfall forecasts to determine when high river events may occur to provide information for any necessary public or industry notifications. We closely monitor river levels and provide advisories if river levels may become unsafe for shipping.
