Engineers (USACE) completed the Carr Creek Dam project in 1975. The Carr Creek Lake Dam is located on Carr Creek, 8.8 miles above its confluence with the North Fork Kentucky River. The project is located in southeastern Kentucky, approximately 16 miles east of Hazard, Kentucky, and 160 air miles southeast of Louisville, Kentucky. The dam operates primarily as a unit with Buckhorn Dam to reduce flood stages in the upper Kentucky River Basin. The project also operates with other USACE lakes to reduce flood stages along the Ohio River. The areas that are most directly benefited include the cities of Hazard, Jackson, and\nBeattyville, Kentucky. A secondary purpose of the project is to provide storage for water supply, land water quality control and a pool for recreation and fish and wildlife activities. The drainage area is 58.2 square miles. It consists of a 750-foot-long earth and rock fill dam having a maximum height of 130 feet, a gate-controlled outlet works along the base of the right abutment, and a 265-foot-wide uncontrolled open cut spillway through the left abutment ridge upstream of the dam. The record pool elevation is 1049.5 feet NAVD88 which occurred on August 2, 2022.", "riskCharSummary":"USACE completed a risk assessment for Carr Creek Lake Dam in the 2023 Periodic Assessment Report, with a risk characterization of very low risk. A potential scenario that could cause uncontrolled release downstream, although extremely unlikely, is internal erosion at the rock foundation and embankment material interface. As the reservoir rises, the seepage flow velocity becomes high enough to initiate scour of the impervious core at the interface. The erosion of material leads to a collapse of fill zones, and nothing is present to act as a crack filler. The embankment consequently becomes unstable, and breach of the dam occurs. Erosion of the spillway during a significant precipitation event is also another extremely unlikely potential scenario. The geology of the spillway is conducive to erosion during an event that achieves spillway flow. As the reservoir rises, erosion of surficial material initiates and begins the erosion process. Continued rise of the reservoir results in increased flow velocities and deeper erosion into the unlined spillway channel. The erosion channel connects to the reservoir, circumvents the dam embankment, and results in increased uncontrolled discharge of the reservoir (breach).\nOvertopping of the embankment is also considered a potential failure mode. There is a lower elevation area at the right abutment along the crest of the dam. In the event of extreme precipitation, water would likely begin to flow in this lower elevation area and begin the erosion process. Once the grass cover is removed, continued and increased erosion is likely, potentially resulting in breach of the dam.\n\nDue to the proximity of the small towns of Vicco, Sassafras, Scuddy, and Happy, and the city of\nHazard (a distance of 15 miles downstream of the dam), the life loss consequences are\nexpected to be large. The short arrival time and the extreme depth of the flow would create\nalmost instant consequences for the surrounding downstream areas.", "riskManagementMeasures":"USACE is continuously taking steps to reduce the risk to the public. This includes regularly updating the Emergency Action Plan (EAP), working closely with local emergency managers, and performing emergency exercises with state and local response teams. USACE regularly inspects and monitors instrumentation to monitor the status of the dam and these inspections increase in frequency when the lake level rises. This ensures that the structure is performing as designed and may help detect any areas of potential concern. Regular maintenance and repairs are performed as needed to keep the dam functioning properly.", "riverName":"CARR CREEK", "separateStructuresCount":3, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":285, "stateFedId":"KY03056", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":132, "submitDate":"2023-11-09T00:00:00.000Z", "surfaceArea":710, "volume":929000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1975, "congDist":"Congressional District 05, Kentucky", "city":"VICCO", "county":"Knott", "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":"Carr Fork Lake Dam", "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Carr Creek Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;5", "dsacId":5, "femaRegion":"4", "lastEapExcerDate":"2024-05-07T12:00:00.000Z", "dataUpdated":"2025-04-30T12:00:00.000Z", "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":26.1629, "tenthPercentile":24.4062, "ninetiethPercentile":28.4862 }, "id":269109, "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/269109?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/269109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/269109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
