Buckhorn Lake Dam in late 1959, starting full operation in 1960. The Buckhorn Lake Dam is located on the Middle Fork of the Kentucky River, 43.3 miles above its confluence with the Kentucky River. The project is located in Southeastern Kentucky, approximately 20 miles northwest of Hazard, Kentucky and 0.5 miles south of Buckhorn, Kentucky. The dam operates as a unit with Carr Creek Lake to reduce flooding in the Kentucky River Basin with the areas that are most directly benefited include the cities of Buckhorn and Beattyville, Kentucky. The Buckhorn Lake project consists of a 1,020-foot rock filled dam with a central clay core, having a maximum height of 160 feet above streambed, a gate controlled outlet works along the right abutment of the dam, and a gate controlled, open cut spillway through the right abutment ridge. The project also has a drainage area of 408 square miles. The record pool elevation of 839.4 feet occurred on 18 March 1963.", "riskCharSummary":"USACE completed a risk assessment for Buckhorn Lake Dam in 2022 that characterizes the risk of the project as low risk. The dam significantly reduces the risk of flooding to downstream communities. However, it does not completely eliminate the risk. Although the Buckhorn Dam has historically performed well, extreme rainfall may cause areas downstream to be flooded. Even when the dam operates as intended, downstream flooding could still occur if a very large rainfall event were to require unusually large quantities of water to be released through the dam spillway. The dam can only hold rainfall that occurs upstream of the dam. This region is prone to flash flooding due to the steep terrain. A potential failure mode is erosion of the dam's earthen embankment during a period of high reservoir levels that could lead to a breach of the dam. In this unlikely event, an uncontrolled surge of water could flow out of the reservoir, resulting in potentially deadly flooding along the Middle Fork of the Kentucky River. The largest impacts\nwould be to Buckhorn, Kentucky, directly below the dam. Low lying areas along the Middle Fork and the main stem of the Kentucky River would experience heavy flooding. The communities of Buckhorn, Beattyville, Irvine/Ravenna are the largest population areas impacted. Lesser flooding would be experienced along the Kentucky River to its confluence with the Ohio River.\n\nUpstream impacts to roadways will occur when the reservoir approaches Elevations above 805 ft NGVD29. These impacts increase in depth and duration at higher pool elevations and restrict residential access to many homes along State Hwy 257. Full flood storage is Elevation 840 ft NGVD29 at which time, the spillway gates are opened to regulate the reservoir level. Residents downstream and around the reservoir are encouraged to pre-plan emergency routes.", "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 regularly inspects and monitors instruments to check the health 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. Flood-fighting materials are stockpiled at the project and readily available for use during emergency conditions.", "riverName":"MIDDLEFORK KENTUCKY RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":140, "stateFedId":"KY03027", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":160, "submitDate":"2023-11-09T13:18:46.464Z", "surfaceArea":1230, "volume":1500000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1960, "congDist":"Congressional District 05, Kentucky", "city":"BUCKHORN", "county":"Perry", "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":"Buckhorn Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":4, "femaRegion":"4", "lastEapExcerDate":"2024-05-08T12:00:00.000Z", "dataUpdated":"2025-06-27T12:00:00.000Z", "usaceDistrict":"Louisville District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"051002", "doi_region":null, "doi_region_name":"North Atlantic-Appalachian", "doi_region_number":1, "thirtyYearAverage":35.2114, "tenthPercentile":25.1144, "ninetiethPercentile":64.1718 }, "id":265109, "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/265109?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/265109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/265109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
