located at River Mile 12.3 on the Big Blue River, in Pottawatomie and Riley Counties, Kansas, approximately 5 miles north of Manhattan, Kansas. The main components of the project are an embankment dam, outlet works with two gated conduits, a controlled spillway, and the Blue Rapids levee located upstream. The Blue Rapids Levee was constructed as part of the dam construction project for Tuttle Creek. The primary consequence center is Manhattan, Kansas, approximately 5 miles downstream of the dam.", "riskCharSummary":"Tuttle Creek Dam is currently categorized as moderate risk (Dam Safety Action Classification 3) based on the 2020 risk assessment. The risk driving potential failure modes for the 2020 risk assessment were: 1) overtopping of the main embankment dam during an extreme flood event; 2) spillway headcut erosion initiating at the unlined spillway; and 3) spillway headcut erosion initiating at the chute slabs. There is a significant risk of downstream flooding during a spillway release with the dam functioning properly.", "riskManagementMeasures":"USACE will continue to work closely with state and local emergency managers, conduct emergency exercises and incorporate any new information into our collective emergency action plans. We will continue rigorous monitoring and surveillance of the dam and will do so more frequently when heavy rainfall causes high reservoir levels. Rainfall forecasts and reservoir levels are routinely monitored and if a high reservoir level is forecasted, we will promptly inform local and state emergency managers so that they can take protective actions, make flood warnings, and prepare for emergency responses. We will work with communities downstream of the dam to help them understand how they can better prepare for a potential flood.", "riverName":"BIG BLUE RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":1, "spillwayWidth":839, "stateFedId":"KS00012", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":157, "submitDate":"2023-02-16T17:25:34.576Z", "surfaceArea":13350, "volume":17600000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1960, "congDist":"Congressional District 01, Kansas", "city":"MANHATTAN", "county":"Pottawatomie", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/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":null, "otherNames":"Tuttle Creek Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;12;3;4;5", "dsacId":3, "femaRegion":"7", "lastEapExcerDate":"2025-02-27T12:00:00.000Z", "dataUpdated":"2025-04-14T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"102702", "doi_region":"MB", "doi_region_name":"Missouri Basin", "doi_region_number":5, "thirtyYearAverage":407.76, "tenthPercentile":295.5476, "ninetiethPercentile":453.8399 }, "id":5722030, "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/5722030?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/5722030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/5722030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
