primary purpose to reduce flooding in downstream communities as well as water supply, fish and wildlife, and for recreation. Big Hill Dam is located on Big Hill Creek, a tributary of the Verdigris River 5 miles east of Cherryvale, Kansas. Big Hill Dam consists of an earth-fill embankment, a gate tower outlet works with a drop inlet, and a separate uncontrolled spillway. The outlet works includes a wet well and water supply intake.", "riskCharSummary":"USACE completed a risk assessment in May 2020 and classified the risk of Big Hill Dam as low. Although extremely unlikely, the two primary risks to the integrity of the dam are: (1) A flood so large that the capacity of the dam to store water is exceeded and water flows over the top of the dam, and (2) A flood so large that it flows through the auxiliary spillway and erodes the spillway bottom back to the lake resulting in additional releases. Failure of the dam would result in flooding in Liberty, Kansas; Coffeyville, Kansas; and rural areas along the Verdigris River in Kansas and Oklahoma. There is also flood risk associated with the dam due to normal operation of the dam which could include large releases through the ungated spillway during a large flood.", "riskManagementMeasures":"USACE is taking several actions to manage and reduce the risk that Big Hill Dam poses to communities. Along with routine inspections and surveys additional efforts include establishing emergency rock and sand stockpiles, emergency exercises, annual updates to the Emergency Action Plan, and development of a communication plan to communicate dam risks. \nAdditionally, there are numerous activities that USACE conducts on a day-to-day basis to help manage risk. The dam is well maintained through continuous operations and maintenance activities and USACE conducts detailed inspections of the dam during both normal lake levels and during flood events to ensure the integrity of the structure. Lastly, the dam has instrumentation and monitoring system to allow USACE staff to evaluate the dam for changing conditions.", "riverName":"BIG HILL CK", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":400, "stateFedId":"KS00049", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":83, "submitDate":"2023-02-16T17:25:38.354Z", "surfaceArea":1192, "volume":2189036, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1981, "congDist":"Congressional District 02, Kansas", "city":"CHERRYVALE", "county":"Labette", "aiannh":null, "websiteUrl":"https://www.swt.usace.army.mil/Locations/Tulsa-District-Lakes/Kansas/Big-Hill-Lake/", "coreTypeIds":"3", "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Pearson-Skubitz Big Hill Dam", "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CESWT", "otherNames":"Big Hill Lake", "ownerNames":"USACE - Tulsa District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5;8", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2024-11-13T12:00:00.000Z", "dataUpdated":"2025-07-15T12:00:00.000Z", "usaceDistrict":"Tulsa District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110701", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":31.7313, "tenthPercentile":28.8137, "ninetiethPercentile":34.0703 }, "id":1595051, "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/1595051?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/1595051?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/1595051?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
