Pomme De Terre Dam is located on the Pomme De Terre River, two miles south of Hermitage. It is the only dam along the Pomme de Terre River before it enters the Osage River as an arm of Truman Lake. Downstream of the dam is the community of Hermitage, Missouri and the Harry S. Truman Reservoir. The dam was authorized for flood control, water quality, recreation, fish & wildlife enhancement. Additional authorized purposes include navigation and water supply, but the lake is not regulated for these purposes. Pomme De Terre Dam has reduced flood damage by more than an estimated $144 million (2021 price level) from 1961 to 2021. The dam is 4,630 feet long composed of rolled earth and rock fill. The top of the dam sits approximately 155 feet above the stream. Additionally, the Pomme De Terre Lake project contains a dike next to the left abutment to complete the reservoir rim.", "riskCharSummary":"USACE is confident that the dam is solidly built, well maintained, and will continue to significantly reduce flood risks. However, the dam alone cannot eliminate all flooding. Extreme rainfall events that exceed Pomme De Terre\u2019s storage capacity causing the release of water down the uncontrolled spillway, even if the river at or beyond capacity to prevent overtopping and failure of dam. This can result in flooding at downstream areas or can worsen already existing flooding downstream due to the rivers being over capacity. \n\nUSACE completed a risk assessment for Pomme De Terre Dam in May 2022 to determine the ability of USACE to meet the flood risk management goals of the dam. As a result, the risk due to dam breach is characterized as low. In an extreme flood scenario, inflows into the lake may exceed the storage and release capacity of the dam, and overtopping may occur. If overtopping occurs the earthen embankment of dam could erode leading to a sudden release of water downstream. This would result in extreme flooding in Hermitage, Missouri and high levels in Harry S. Truman Lake.", "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 lake levels. Rainfall forecasts and lake levels are routinely monitored and if a high lake 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 that are developing downstream of the dam to help them understand how they can better prepare for a potential flood.", "riverName":"POMME DE TERRE RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":170, "stateFedId":"MO30201", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":155, "submitDate":"2023-02-16T17:25:13.192Z", "surfaceArea":7820, "volume":6150000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1961, "congDist":"Congressional District 04, Missouri", "city":"HERMITAGE", "county":"Hickory", "aiannh":null, "websiteUrl":"https://www.nwk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"5;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CENWK", "otherNames":"Pomme De Terre Lake", "ownerNames":"USACE - Kansas City District", "ownerTypeIds":"3", "primaryDamTypeId":5, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;4;5;8", "dsacId":4, "femaRegion":"7", "lastEapExcerDate":"2025-02-05T12:00:00.000Z", "dataUpdated":"2025-07-03T12:00:00.000Z", "usaceDistrict":"Kansas City District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"102901", "doi_region":null, "doi_region_name":"Mississippi Basin", "doi_region_number":4, "thirtyYearAverage":333.3152, "tenthPercentile":303.037, "ninetiethPercentile":362.2759 }, "id":15222030, "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/15222030?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/15222030?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/15222030?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
