"politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) completed Brookville Dam in 1974. Brookville Dam is located on the East Fork of the Whitewater River, 2.2 miles above its junction with the Whitewater River and roughly 0.5 miles north of Brookville, Indiana. The project is located approximately 60 air miles east of Indianapolis, Indiana, and approximately 35 miles northwest of Cincinnati, Ohio. The Brookville Lake project consists of the following structures: a 2,900 foot long earth-filled embankment with a maximum height of 181 feet, a gate controlled outlet along the base of the right abutment, and an uncontrolled, open cut spillway with an average width of 210 feet through the right abutment. The outlet works and spillway discharge into the East Fork of the Whitewater River. At spillway crest, the reservoir extends up the East Fork of the\nWhitewater River about 18 miles. Brookville Dam reduces flooding along the East Fork of the Whitewater River and the Whitewater River to its confluence with the Ohio River. It has a drainage area of approximately 379 square miles. The record pool elevation of 766.67 ft-NAVD88 occurred in May of 2011. Dunlapsville Levee is an associated structure located approximately 11 miles north of the dam.", "riskCharSummary":"USACE completed a risk assessment for Brookville Lake Dam in June 2023 that characterizes the risk of the project as a Dam Safety Action Classification (DSAC) 3 which is considered Moderate 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 internal erosion of the dam\u2019s earthen embankment during a period of high reservoir levels leading 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 Whitewater River. Another devastating scenario, although more unlikely, would be an overtopping event where water exceeds the capacity of the dam and flows over the embankment crest, eroding embankment material leading to a breach of the dam. \n\nIf a dam failure occurred, water from the reservoir would flood downstream areas. The town of Brookville, IN located within a mile of the toe of the dam would be significantly impacted including essential structures such as fire stations, EMS facilities, electrical substations, school buildings, hotels, and wastewater treatment facilities. Flooding would also impact many local roadways including evacuation routes such as Highway 52. Although these scenarios are considered extremely unlikely, Brookville Dam has an emergency action plan to lower the risk of life loss if any of these scenarios occurred.", "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 regularly 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 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":"EAST FORK OF WHITEWATER RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":70, "stateFedId":"IN03017", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":181, "submitDate":"2023-12-06T14:00:11.769Z", "surfaceArea":5260, "volume":6731700, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1974, "congDist":"Congressional District 09, Indiana", "city":"BROOKVILLE", "county":"Franklin", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":"3", "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":"Brookville Lake", "ownerNames":"USACE - Louisville District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5;8", "dsacId":3, "femaRegion":"5", "lastEapExcerDate":"2025-02-28T12:00:00.000Z", "dataUpdated":"2025-06-06T12:00:00.000Z", "usaceDistrict":"Louisville District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"050800", "doi_region":null, "doi_region_name":"Great Lakes", "doi_region_number":3, "thirtyYearAverage":null, "tenthPercentile":null, "ninetiethPercentile":null }, "id":125109, "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/125109?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/125109?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/125109?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
