The Rough River Lake project is located in south-central Kentucky, approximately 60 miles southwest of Louisville, Kentucky, and 20 miles northwest of Leitchfield, Kentucky. The project consists of a 1,590-foot-long earth-filled embankment with a maximum height of 130 feet, a gate-controlled outlet works along the base of the right abutment, and a 65-foot wide, uncontrolled open-cut spillway through the left abutment. The project reduces flood damages along approximately 89 miles of the Rough River, approximately 71 miles on the Green River, and to a lesser extent on the Ohio and Mississippi Rivers. The project has a drainage area of approximately 454 square miles. At spillway crest (EL. 523.57 ft-NAVD88), the reservoir extends up the Rough River\napproximately 45 miles. The record pool occurred in May of 2011 where the pool elevation reached 526.88 ft-NAVD88 and resulted in discharge from the spillway and high releases from the dam\u2019s outlet. During the record pool, peak depth for spillway flows was approximately 3.3 feet.", "riskCharSummary":"USACE completed a risk assessment for Rough River Dam in February 2023 that characterizes the risk of the project as a Dam Safety Action Classification (DSAC) 2 which is considered High relative to the dams USACE owns and operates. This classification is based on the existing conditions and the potential for flood impacts to downstream communities. Although very unlikely, the primary risks to the integrity of the dam are: (1) Internal erosion of the dam\u2019s earthen embankment during a period of high reservoir levels and (2) A large flood event that exceeds the capacity of the dam to store water and water flows over the top of the dam even with maximum possible releases being made through the gates. These unlikely events could cause an uncontrolled surge of water to flow out of the reservoir and lead to breach. This would result in catastrophic flooding downstream, widespread economic impacts, and significant loss of life.\n\nIf a dam failure occurred, water from the reservoir would flood downstream communities. The largest impacts would be to Falls of Rough, Kentucky. Although consequences are generally concentrated in Falls of Rough, flooding would also impact several other small, rural towns located adjacent to the river, such as Dundee, Hartford, and Livermore, Kentucky. As reservoir levels rise, upstream areas will also be impacted. Impacts include flooding of local roads such as access roads to surrounding camp and visitor areas as well as flooding on State Routes 79, 110, 259 and many county roads.", "riskManagementMeasures":"To help mitigate risks associated with Rough River, USACE is implementing a Dam Safety Modification Project. Phase I of remedial construction which included foundation grouting of defects in the limestone bedrock was completed in May 2017. This was accomplished from the crest of the dam with re-routing of State Hwy 79 to an upstream bench. Phase 2 is currently under design and will include a full depth concrete cut-off wall along the crest of the dam and a new outlet works through the left abutment.\n\nUSACE is continuously taking significant steps on a day-to-day basis 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 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.", "riverName":"ROUGH RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":65, "stateFedId":"KY03012", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":132, "submitDate":"2023-11-14T16:07:07.471Z", "surfaceArea":5100, "volume":1074000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1959, "congDist":"Congressional District 02, Kentucky", "city":"FALLS OF ROUGH", "county":"Grayson", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":null, "damTypeIds":"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":"Rough River Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5;8", "dsacId":2, "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":144.4466, "tenthPercentile":91.5868, "ninetiethPercentile":223.99 }, "id":1162109, "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/1162109?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/1162109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1162109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
