Green River Dam is located on the Green River, 305.7 miles above its confluence with the Ohio River. The project is located in Taylor and Adair Counties in southcentral Kentucky, approximately 90 air miles south-southwest of Louisville, Kentucky, and 10 miles southwest of Campbellsville, Kentucky. The Green River Project consists of the following structures: an earth and rock fill dam, an earth filled dike, a gate-controlled outlet works along the base of the right abutment of the dam, and a 450-foot wide, uncontrolled, open cut spillway through the ridge between the dam and the dike. The dam embankment is 2,350 feet long with a maximum height of 143 feet. The dike consists of a 1,952-foot-long earthen embankment with a maximum height of 105 feet. Green River Dam reduces flooding along the Green River to its confluence with the Ohio River. The dam has a drainage area of approximately 682 miles. The record pool elevation of 704.71 ft-NAVD88 occurred in January 1979, and did not result in spillway flow (El 712.51 ft NAVD88).", "riskCharSummary":"USACE completed a risk assessment for Green River Dam in June 2017 that characterizes the risk of the project as a Dam Safety Action Classification (DSAC) 4 which is considered Low relative to the dams USACE owns and operates. The dam significantly reduces the risk of flooding to downstream communities. However, it does not eliminate the risk completely. Even when the dam operates as intended, downstream flooding could still occur if a very large rainfall event were to result in unusually large quantities of water to flow through the dam spillway. There is also a very unlikely, but far more devastating scenario that would produce significant flooding, which is erosion of the dam and/or dike earthen embankment during a period of high reservoir levels that could lead to a breach of the dam and/or dike. In this unlikely event, an uncontrolled surge of water could flow out of the reservoir, resulting in potentially deadly flooding along the Green River.\n\nIf a dam failure occurred, water from the reservoir would flood downstream areas. The largest impacts would be Greensburg, Brownsville, and Morgantown, Kentucky. In Greensburg, flooding would impact essential structures such as police stations, fire stations, electric substations, and school buildings.", "riskManagementMeasures":"USACE is continuously taking steps to reduce the risk to the public. This includes working closely with local emergency managers, regularly updating the Emergency Action Plan, and conducting emergency exercises with state and local response teams. USACE utilizes the latest forecast, and stream gauge information and coordinates closely with the National Weather Service concerning conditions both upstream and downstream of the dam including inflow, outflow, and precipitation. Rainfall forecasts are used to determine when high pool events may occur. USACE monitors on-site instruments and conducts regular inspections to ensure the health and integrity of the dam. The frequency of these inspections increases when the lake level rises. This ensures 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.", "riverName":"GREEN RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":450, "stateFedId":"KY03007", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":144, "submitDate":"2023-11-16T14:56:16.748Z", "surfaceArea":8210, "volume":4741000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1969, "congDist":"Congressional District 01, Kentucky", "city":"GREENSBURG", "county":"Taylor", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":null, "damTypeIds":"5;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"CELRL", "otherNames":"Green River Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5;8", "dsacId":4, "femaRegion":"4", "lastEapExcerDate":"2025-03-05T12:00:00.000Z", "dataUpdated":"2025-04-22T12:00:00.000Z", "usaceDistrict":"Louisville District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"051100", "doi_region":null, "doi_region_name":"North Atlantic-Appalachian", "doi_region_number":1, "thirtyYearAverage":312.8583, "tenthPercentile":278.797, "ninetiethPercentile":378.2324 }, "id":1108109, "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/1108109?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/1108109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1108109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
