        "projectDescription":"The U.S. Army Corps of Engineers (USACE) built Allegheny 5 Lock and Dam in 1927 across the Allegheny River.  The dam is located in Armstrong County Pennsylvania, about 30 miles upstream of the confluence of the Allegheny and Monongahela Rivers in Pittsburgh, PA. The purpose of the dam is to create a navigation pool from the dam to Allegheny 6 Lock and Dam, which is near located near Freeport, PA. 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, which is the height of the river level upstream of the dam (upper pool) to the river level downstream of the dam (lower pool).  The lock allows river traffic to travel upstream and 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 sides.  The economic benefits of shipping materials and goods through the lock is more than 1 million dollars annually.  The pool created by the dam provides recreation opportunities for surrounding communities.  The dam also provides hydropower benefits of near 1 million dollars annually, as a private hydropower facility is located on the left bank in line with the dam. 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 was performed in 2021, which 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 was to fail. Although the dam holds back water, a dam failure at Allegheny 5 Lock and Dam will not result in the flooding of downstream communities.  \n\nIf the pool upstream 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 more than 2 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 dam has performed well for over 90 years without incident.  Due to the relatively short 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.",
        "riskManagementMeasures":"To ensure we are taking all steps to reduce the risk to the public and the economy, we will conduct emergency exercises with our external partners to improve communications and reactions in the event navigation is lost.  We regularly update our emergency action plan.  We will also communicate with the Coast Guard, the Waterways Association, and the shipping industry to keep them aware of conditions at the dam and any changes to lock operations. We conduct routine monitoring and surveillance of the riverbed, lock, and dam.  We closely follow rainfall forecasts and river levels to determine when high river events may occur to provide information for any necessary public or industry notifications. Information on river levels and forecasts are available to the public via the internet at:  \n\nhttps://waterdata.usgs.gov/monitoring-location/03039040/#parameterCode=00065&period=P7D",
