"politicalPartyId":null, "privateDamId":null, "projectDescription":"The John Hollis Bankhead Lock and Dam was authorized by Congress in the 1909 under the River and Harbors Act to generate hydropower, reduce flooding in downstream communities, navigation, and recreation. Bankhead Dam is located on the Black Warrior River 23 miles upstream of Tuscaloosa, Alabama. It was designed and constructed from 1911 to 1915 by the U.S. Army Corps of Engineers (USACE) to provide for the needs of navigation. The project was later modified to increase navigation channel depth to 9 feet in 1936. In the late 1960\u2019s, the spillway was raised, and a new navigation lock was constructed on the east side of the river.\n\nThe dam is constructed of concrete, with a gated spillway, non-overflow dam, lock, and powerhouse. Water is released into the river through the spillway or through the turbines in the powerhouse. The spillway is 1,170 feet long with a crest elevation of 241.5 feet and 22 gates. The single lift lock is 600 feet long and 110 feet wide with a lift of 69 feet. Alabama Power Company owns and operates the powerhouse on the west end of the spillway.\n\nThe project provides an annual navigation benefit of about $300 million annually and also provides regional hydropower benefits.", "riskCharSummary":"USACE completed a risk assessment in 2015 that classified the risks associated with the John Hollis Bankhead Lock and Dam as Moderate. The dam was found to be well-constructed and well-maintained and is expected to be reliable during major floods. The dam could possibly be damaged or fail due to a nearby major earthquake of a magnitude that has not been experienced before in the area. If this unlikely scenario were to occur flood waters would be extremely swift and deep and cause flooding downstream, economic impacts, and potentially loss of life. In the unlikely event of a dam failure the largest impacts would be along the riverfront downstream of the dam, in areas of Tuscaloosa and Northport, Alabama. Key infrastructure along the river could be damaged or destroyed and historic flooding on the river would occur to the vicinity of Demopolis, Alabama.", "riskManagementMeasures":"USACE is continuously working to manage the risk to the public. This includes sharing flooding maps with state and county emergency managers, regularly updating the Emergency Action Plan, and conducting emergency exercises with state and local response teams. USACE regularly inspects and monitors instruments to assess the condition of the dam. The frequency of these checks increases when the lake level rises. This ensures that the structure is performing as designed and could help detect any areas of potential concern. Regular maintenance and repairs are performed as needed to keep the dam functioning properly.\n\nSuggestions to improve flood risk awareness:\n\nExamine breach and non-breach flood inundation layers to the right (from the NID Map Viewer, Layer Controls).\n\nConnect with your local representatives and officials to sign up for personalized alerts.\nAlabama EMA Alerts and Warnings\thttps://ema.alabama.gov/publicnotice\n\nTuscaloosa County Emergency Management Agency https://www.tuscaloosacountyema.org/\n\nCreate a family emergency plan and determine your evacuation route with the goal of getting to higher ground. \nVisit: www.ready.gov\n\nConsider purchasing flood insurance to protect your property.\nVisit: www.fema.gov/national-flood-insurance-program\n\nConnect with the USACE to learn more about John Hollis Bankhead Lock and Dam. \nFollow the Mobile District on Facebook at www.facebook.com/USACEMOBILE/", "riverName":"BLACK WARRIOR RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":1023, "stateFedId":"AL01427", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":111, "submitDate":"2023-02-16T17:25:41.814Z", "surfaceArea":9245, "volume":316000, "widthOfLocks":110, "secondaryWidthOfLocks":null, "yearCompleted":1975, "congDist":"Congressional District 04, Alabama", "city":"HOWSE CAMP", "county":"Tuscaloosa", "aiannh":null, "websiteUrl":"https://www.sam.usace.army.mil/Missions/Civil-Works/Recreation/Black-Warrior-Tombigbee-BWT-Lakes/", "coreTypeIds":null, "damTypeIds":"9", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1;13", "fedOperationIds":"1", "fedOtherIds":"13", "fedOwnerIds":"1", "fedRegulatoryIds":"1;13", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"Alabama Power Co.;CESAM", "otherNames":"Lake Bankhead", "ownerNames":"USACE - Mobile District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":3, "purposeIds":"3;5;6", "dsacId":3, "femaRegion":"4", "lastEapExcerDate":"2024-08-07T12:00:00.000Z", "dataUpdated":"2025-02-06T13:35:18.809Z", "usaceDistrict":"Mobile District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"031601", "doi_region":null, "doi_region_name":"South Atlantic Gulf", "doi_region_number":2 }, "id":13720039, "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/13720039?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/13720039?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/13720039?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
