Kerr Scott Dam in 1962 across the Yadkin River. Located 3.7 miles upstream of Wilkesboro, North Carolina, the dam is comprised of compacted earth that forms an embankment between two hillsides. The dam is almost 150 feet tall and approximately a third of a mile long and is operated and maintained by USACE. The dam reduces the risk of flooding to the Towns of Wilkesboro, North Wilkesboro, and other smaller downstream communities. Following large storms, flood waters accumulate in the reservoir and then USACE releases the water over time at non-damaging rates after downstream conditions improve (primarily based on river stages at Wilkesboro). USACE makes all decisions about releasing water from the reservoir using the Water Control Manual, created specifically for conditions in the Yadkin River Basin. USACE generally releases water from the reservoir through a concrete outlet tunnel. The dam also has an auxiliary spillway, an engineered 400-foot-wide notch in the nearby hillside on the north side of the dam, designed to divert water from the reservoir before it can flow over the top of the dam. To date, water levels have never reached high enough to flow through the auxiliary spillway.", "riskCharSummary":"Dams do not eliminate all risk of flooding. USACE works to address all types of flood risk associated with the dam. Dams have limited capacity to store water. Water may be released through the dam to manage water levels up or downstream or to relieve pressure on the dam to maintain its structural integrity. Severe weather events that bring inconsistent or larger amounts of water into the system can also lead to dam releases or in some cases overwhelm and lead to issues occurring at a dam. More detail related to this specific dam will be added at a future time.", "riskManagementMeasures":"To minimize flood risks associated with W. Kerr Scott Dam, USACE utilizes the latest forecast and stream gauge information to predict precipitation, inflow, and outflow. USACE coordinates closely with the National Weather Service and the U.S. Geological Survey, concerning conditions both upstream and downstream of the dam. USACE works with these partners and local and state emergency management officials to prepare and practice for emergency response efforts. USACE provides local emergency managers and risk managers with detailed information about the dam and the potential worst-case scenario flood data, including flood depths and arrival times, so they can prepare for and act in a timely manner during an event. \n\nDuring high water events, USACE dam safety professionals continuously monitor the dam and are prepared to act if issues arise. USACE also regularly inspects the dam and routinely re-assesses the risks associated with the dam. Were a dam emergency to occur, USACE would be in constant communication with local and state emergency managers to ensure they can maximize time to alert and evacuate the public. USACE recently updated the dam\u2019s Emergency Action Plan to enhance these coordination efforts.\nUSACE has recently created a digital site characterization model to better understand the internal structure of the dam and has surveyed the top of the dam to determine presence and location of low spots along the crest. USACE also installed additional instrumentation to help with monitoring the condition of the dam.", "riverName":"YADKIN RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":400, "stateFedId":"NC00300", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":148, "submitDate":"2023-08-01T18:19:48.267Z", "surfaceArea":1475, "volume":2240000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1963, "congDist":"Congressional District 05, North Carolina", "city":"WILKESBORO", "county":"Wilkes", "aiannh":null, "websiteUrl":"https://www.saw.usace.army.mil/Locations/District-Lakes-and-Dams/W-Kerr-Scott/", "coreTypeIds":"3", "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"COE", "otherNames":"W.
