A dam is an earthen embankment and/or solid concrete structure that is built across a river, stream, or other waterway to temporarily hold back and store water that would otherwise flow downstream. More detail related to this specific dam will be added at a future time.", "riskCharSummary":"Breach risk for this dam has been asssessed to be very low. Flood inundation maps and breach consequence estimates have been developed for this dam since there is potential loss of life should it fail or be mis-operated. This dam is authorized, designed, and operated for water supply and flood damage reduction and stores water for those purposes. In the unlikely event of a dam failure with low or normal water flows in the river, flooding nearby could occur. During high flow events, the dam is operated to store water to reduce downstream flooding that would occur naturally. But during a very large flood, flooding could occur downstream, and failure would result in additional flooding downstream. Flood mapping has been developed to indicate potential flooding extents during a range of river conditions. These maps should be used by the public and state and local emergency managers for their awareness and preparedness in the event of a dam breach incident.", "riskManagementMeasures":"USACE manages dam-related flood risks by assessing the condition of the dam by monitoring and routine inspection. Regular maintenance and repairs are performed as needed to keep the dam functioning properly. USACE prioritizes maintenance and repairs that will most impact the risks, and engages upstream and downstream emergency managers and members of the public to raise awareness of the dam and support actions to prepare and be ready to respond in the case of a dam-related incident. USACE periodically updates the emergency action plan for this dam and periodically convenes with state and local emergency managers to share what is known about the dam and to support the development of state and local preparedness and response plans.", "riverName":"Okatibbee Creek", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":1500, "stateFedId":"MS01491", "stateRegulatoryAgency":"MS DEPARTMENT OF ENVIRONMENTAL QUALITY", "stateRegulatedId":1, "structuralHeight":72, "submitDate":"2023-02-16T17:25:39.770Z", "surfaceArea":3800, "volume":2053000, "widthOfLocks":null, "secondaryWidthOfLocks":null, "yearCompleted":1968, "congDist":"Congressional District 03, Mississippi", "city":"Meridian", "county":"Lauderdale", "aiannh":null, "websiteUrl":"https://www.sam.usace.army.mil/Missions/Civil-Works/Recreation/Okatibbee-Lake/", "coreTypeIds":null, "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":"CESAM", "otherNames":"Okatibbee Lake", "ownerNames":"USACE - Mobile District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5;8", "dsacId":5, "femaRegion":"4", "lastEapExcerDate":"2024-08-07T12:00:00.000Z", "dataUpdated":"2024-12-17T12:00:00.000Z", "usaceDistrict":"Mobile District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"031700", "doi_region":null, "doi_region_name":"Mississippi Basin", "doi_region_number":4, "thirtyYearAverage":48.6673, "tenthPercentile":44.6596, "ninetiethPercentile":52.3076 }, "id":26407039, "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/26407039?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/26407039?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/26407039?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
