The dam is located in Stratton, OH, about 54 miles downstream of Pittsburgh, Pennsylvania. The purpose of the dam is to create a navigation pool from the dam upstream to Montgomery Locks and Dam, located near Monaca, Pennsylvania. The dam is concrete and includes eleven gated bays through which the Ohio River flows. The locks provide a lift of about 21 feet, from the pool downstream of the dam (lower pool) to the pool above the dam (upper pool). The locks allow river traffic to travel upstream or downstream of the dam. The locks include a main chamber that is 110 feet wide by 1200 feet long and a second, auxiliary chamber, that is 110 feet wide by 600 feet long. The lock chambers are adjacent to each other and are formed on each side by concrete walls and steel gates on the upstream and downstream sides. The pool created by the dam also provides water supply to municipal and industrial intakes, and recreational purpose. The total benefits to the region are more than 470 million dollars annually. The dam does not provide the nearby communities with any protection from flooding.", "riskCharSummary":"The most recent risk assessment of the dam was performed in 2018, which characterized the risk as low. The assessment identified two scenarios that could cause the dam to fail, which would release water from the upper pool: 1) A runaway barge could become trapped on the dam which could prevent one or more dam gates from closing; and 2) The riverbed downstream of the dams could erode to the extent that portions of the dam move downstream. Either of these scenarios, although very unlikely could result in a loss of the upper pool to the extent that river traffic would be halted. If the upper pool were lost, the primary consequences would be the loss of shipping and water supply, which would damage the regional economy by more than 470 million dollars per year. The economic damage would be temporary, until the upper pool could be restored to allow resumption of shipping and water supply. Downstream flooding would not be expected if the dam were to fail, and the upper pool was lost.", "riskManagementMeasures":"To ensure all steps are being taken to reduce the risk to the economy, we conduct routine monitoring and surveillance of the riverbed and locks and dam. We conduct emergency exercises with our external partners to improve communications and reactions in the event of an emergency that threatens the dam\u2019s upper pool or may adversely affect river traffic. We regularly update our emergency action plan. We also communicate with the Coast Guard, the Waterways Association, and the shipping industry to keep them aware of conditions at the dam and the changes to the lock operations. We closely follow rainfall forecasts and river levels to determine when high river events may occur, in order to provide information for any necessary public or industry notifications. We also maintain good communications with industry to remove barges that may run aground near or on our dams. Information on river levels and forecasts are available to the public via the internet at: \n\nhttp://water.weather.gov/ahps2/forecasts.php?wfo=pbz", "riverName":"OHIO RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":1210, "stateFedId":"WV02901", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":64, "submitDate":"2023-02-16T17:25:24.177Z", "surfaceArea":3840, "volume":0, "widthOfLocks":110, "secondaryWidthOfLocks":null, "yearCompleted":1963, "congDist":"Congressional District 06, Ohio", "city":"NEW CUMBERLAND", "county":"Jefferson", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/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":"CELRP", "otherNames":"New Cumberland Pool", "ownerNames":"USACE - Pittsburgh District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":3, "purposeIds":"3", "dsacId":4, "femaRegion":"3", "lastEapExcerDate":null, "dataUpdated":"2025-06-02T12:00:00.000Z", "usaceDistrict":"Pittsburgh District", "noConsequencesId":1, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":2, "damStatusId":2, "huc06":"050301", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3 }, "id":16731111, "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/16731111?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/16731111?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/16731111?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
