The project was authorized by the Flood Control Act of 1938. The authorized project purposes include flood risk management, water supply, water quality control, recreation, and fish and wildlife. \n\nSutton Dam is a high hazard potential dam located just one mile upstream of the Town of Sutton in Braxton County, WV. It is situated on the Elk River, about 100 miles above the mouth at the Kanawha River and 160 miles from the confluence of the Kanawha and Ohio Rivers. \n\nThe dam is a straight concrete gravity structure which includes an overflow spillway section at the river channel, two non-overflow sections at the abutments, training walls, and a curved roller bucket at the toe of the overflow section. The dam has a maximum height of 210 feet above streambed and an overall length of 1,178 feet with its highest elevation at (1016.4 ft on NAVD88 Datum). The top width of the dam is 20 feet, and the maximum base width is 195 feet. Normal outflow is through five gated sluices that exit near the toe of the concrete gravity spillway. The maximum sluice gate discharge is 5000 cfs with all gates fully open at a pool of 1015 ft-NGVD29. A spillway is located in the channel section of the dam that is controlled by gages. Spillway discharge is controlled by six Tainter Gates. Design discharge of the spillway is 222,240 cfs which is 2 times Niagara Falls. \n\nSutton dam helps regulate waters coming from the Elk River in the 537 square mile drainage area upstream of the dam. The dam\u2019s primary function is to provide flood risk management all along the Elk River and Kanawha Rivers including many riverfront communities in Braxton, Clay, Kanawha, Putnam, and Mason counties. West Virginia communities that benefit from Sutton Dam include, but are not limited to, Sutton, Gassaway, Charleston, South Charleston, Dunbar, Saint Albans, Nitro, Poca, Winfield, and Point Pleasant.\n\nSutton Dam routinely releases Elk River waters to keep downstream rivers flowing. However, when it is projected that the Elk, Kanawha, or Ohio Rivers may cause flooding, water coming from upstream of the dam is stored until streams and rivers downstream of the dam recede. Typically storm waters can be released in a controlled manner to reduce flood impacts downstream. However, there are rare storms which can cause more rainfall and runoff than Sutton Dam can store safely. When this occurs, the dam\u2019s spillway gates can be raised to release or spill these waters to reduce the chance that the dam could be overtopped. Opening of the spillway gates will result in flooding downstream of the dam but still far less flooding than would have occurred if the dam was not in place. \n\nWhen the dam is not storing flood waters to reduce flood risks downstream, the dam operates to impound water for flood risk management with secondary purposes of recreation, fish and wildlife conservation, and water quality. This lake is raised in the warmer months to support boat access and lowered in the winter months to provide for additional flood storage capacity.", "riskCharSummary":"While Sutton Dam greatly reduces flood risks downstream, it does not eliminate these\nrisks. Flooding can still occur even if Sutton Dam is operating as designed. There are rare but probable storms, like hurricanes, which cause more rainfall than Sutton Dam can store safely. While hurricanes regularly result in increased precipitation in West Virginia, to affect Sutton Dam, they would have to drop significant rainfall in the Elk River basin which is in the north central part of the state, away from the coast. While this reduces the likelihood of a storm impacting this basin, in some rare occasions, conditions could lead to extreme flows through the spillway which would be about four times as much as Niagara Falls.\n\n\nThe dam\u2019s primary spillway passes these events to keep Sutton Dam from overtopping. When passing these events, flooding is likely in all river-front communities in the Elk and Kanawha River valleys and potentially the Ohio River valley as well. Depending on the amount of water released during these events, significant damages to houses, buildings, factories, roads, bridges, power, and water supply may occur.\n\n\nWhile rare events like these have not occurred to date, if they were to happen, water is likely to reach hillside to hillside quickly and be more than tens of feet deep, depending on the location. In the unlikely event Sutton Dam must pass these extreme waters, follow all directions from emergency officials, including evacuation orders. Failure to do so puts you and your family\u2019s lives at risk.\n\n\nThe risk associated with a dam failure is considered very low. The most substantial risk is the potential of monolith sliding instability along either a deep-seated failure plane (valley center) or at the concrete rock interface (left abutment) due to erosion of the passive wedge either by spillway discharge or overtopping flow during extreme rain events. For a failure in the valley center near monolith 20, approximately 15 feet of massive sandstone must be eroded downstream of the roller bucket to daylight the critical failure plane. This likelihood is extremely low.\n\n\nWhile very unlikely, this concern with the monolith 20 stability could be realized during the passage of extremely rare storms when flooding is already occurring downstream. However, if the dam were to fail, the flooding downstream would dramatically increase. Specifically, warning times would be reduced, and the volume of water and debris carried by the releases would be more like a tidal wave or tsunami increasing the risk to life and property. In the unlikely event the dam was to fail during one of these extreme events, it is critical that you heed all evacuation orders immediately to protect your life.", "riskManagementMeasures":"There are numerous activities that USACE conducts on a day-to-day basis to help manage risk at Sutton Dam. The dam is well maintained through continuous operations and maintenance activities including repairs to one of the spillway gates to eliminate a binding issue, repairing aging instrumentation, and increasing instrumentation to monitor the dam for potential stability issues. USACE conducts detailed inspections of the dam during both normal lake levels and during flood events. Supplementing these inspections, the dam has a specialized instrumentation and monitoring system to allow USACE staff to continually evaluate the dam for changing conditions. Risk management and emergency response actions are being supported by conducting emergency exercises and dam safety training with USACE staff and local and state emergency responders. Additionally, the dam\u2019s Emergency Action Plan is routinely updated to improve emergency response actions.", "riverName":"ELK RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":240, "stateFedId":"WV00701", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":210, "submitDate":"2023-11-28T00:00:00.000Z", "surfaceArea":1520, "volume":611000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1960, "congDist":"Congressional District 01, West Virginia", "city":"SUTTON", "county":"Braxton", "aiannh":null, "websiteUrl":"https://www.lrh.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"2", "damTypeIds":"9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1", "nonFederalDamOnFederalId":0, "designerNames":"CELRH", "otherNames":"Sutton Lake", "ownerNames":"USACE - Huntington District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;4;5", "dsacId":4, "femaRegion":"3", "lastEapExcerDate":"2024-07-25T12:00:00.000Z", "dataUpdated":"2025-04-17T12:00:00.000Z", "usaceDistrict":"Huntington District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"050500", "doi_region":null, "doi_region_name":"North Atlantic-Appalachian", "doi_region_number":1, "thirtyYearAverage":72.4049, "tenthPercentile":54.288, "ninetiethPercentile":77.871 }, "id":259108, "links":[ { "type":"application/json", "rel":"root", "title":"The landing page of this server as JSON", "href":"https://api.wwdh.internetofwater.app?f=json" }, { "type":"text/html", "rel":"root", "title":"The landing page of this server as HTML", "href":"https://api.wwdh.internetofwater.app?f=html" }, { "rel":"self", "type":"application/geo+json", "title":"This document as JSON", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/259108?f=json" }, { "rel":"alternate", "type":"application/ld+json", "title":"This document as RDF (JSON-LD)", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/259108?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/259108?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
