to hold back water during flood events to reduce the risk of downstream flooding on the West Fork, Monongahela, and Ohio Rivers, including metropolitan Pittsburgh. The dam is located about one mile upstream of Weston, West Virginia and forms the Stonewall Jackson Reservoir. The reservoir stores rainfall to maintain downstream flow within the downstream river banks and releases water after flood events. Since it went into operation, the dam has reduced damage caused by downstream flooding by more than an estimated $440 million. The reservoir also serves to store rainfall from late winter through early summer to augment downstream river flow during the drier late summer and early autumn months. The reservoir also provides recreational opportunities to the region, including at the Stonewall Resort State Park, which is situated along the reservoir. Stonewall Jackson Dam is composed of concrete and has a maximum height of 95 feet and has a length of 620 feet. The central portion of the dam contains openings, which form a spillway. The spillway is designed to release a large volume of water to the downstream river during significant rainfall events to reduce the possibility that water from the reservoir will overtop the dam.", "riskCharSummary":"The most recent risk assessment for Stonewall Jackson Dam was completed in 2022, which characterized the risk posed by the dam as very low. The most likely scenario that could result in downstream flooding from Stonewall Jackson Dam would be an uncontrolled high-volume release of water from the dam\u2019s spillway during unusually intense storm events. The frequency and amount of water released could cause flooding in downstream communities. Such water releases from the spillway could create conditions similar to how the river might behave if the dam did not exist. There is also one less likely, but far more devastating scenario that could produce significant flooding during an extreme rainfall event: if the reservoir level rises above the crest of the dam, the overflowing water could erode the soil downstream of the dam, potentially causing a dam breach by allowing one or more of the concrete dam segments to move downstream. If this were to occur, an uncontrolled surge of water would flow out of the reservoir, flooding downstream communities. Weston and other communities located in the valley below the dam are in more immediate danger in the event of a flood. Towns and cities further downstream including Clarksburg and Morgantown, have larger populations and less awareness of the dam, but will also have greater warning times, should a flood occur. In either of the scenarios described above, the downstream floodwater would be swift and deep, overflowing levees, destroying buildings and key infrastructure, and those caught unaware and/or unable to evacuate could perish.", "riskManagementMeasures":"To ensure we are taking all steps to reduce the risk to the public, we will continue to work closely with state and local emergency managers, conducting emergency exercises, and incorporate any new information into our emergency action plan. We will continue our rigorous monitoring and surveillance of the dam, especially during high water events. Rainfall forecasts and reservoir levels are routinely monitored and if a high-water event is forecast, we will promptly inform local and state emergency managers so that they can take protective actions, make flood warnings, and prepare for emergency responses. We will work with local communities to provide opportunities to engage with residents to help them understand how they can better prepare for a potential flood.
