"politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) built Isabella Dam in 1953 after being authorized under the Flood Control Act of 1944. The dam is located 45 miles northeast of Bakersfield, CA and consists of an earth fill main dam across the Kern River and an earthfill auxiliary dam across the adjacent valley, which impound water from the North and South forks of the Kern River to create Lake Isabella. Isabella Dam reduces the risk of flooding primarily to the city of Bakersfield and surrounding communities in Kern County by holding back water during major flood events. Although flood risk management is the project\u2019s primary focus, the dam also provides irrigation, recreation, and environmental stewardship benefits to nearby communities.", "riskCharSummary":"Dams do not eliminate all risk of flooding. USACE works to address all types of flood risk associated with the dam. Dams have limited capacity to store water. Water may be released through the dam to manage water levels up or downstream or to relieve pressure on the dam to maintain its structural integrity. Severe weather events that bring inconsistent or larger amounts of water into the system can also lead to dam releases or in some cases overwhelm and lead to issues occurring at a dam. More detail related to this specific dam will be added at a future time.", "riskManagementMeasures":"USACE manages dam-related flood risks by continually monitoring the condition and health of the dam, prioritizing activities that will most impact the risks, and engaging 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 emergency. USACE works closely with local emergency managers to share what is known about the dam and support the development of local emergency and evacuation plans. USACE regularly updates the emergency action plan for the dam. Regular maintenance and repairs are performed as needed to keep the dam functioning properly. More detail related to this specific dam will be added at a future time.", "riverName":"KERN RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":140, "stateFedId":"CA10106", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":185, "submitDate":"2023-02-16T17:25:42.155Z", "surfaceArea":11200, "volume":0, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1953, "congDist":"Congressional District 20, California", "city":"BODFISH", "county":"Kern", "aiannh":null, "websiteUrl":"https://www.spk.usace.army.mil/Missions/Civil-Works/Isabella-Dam/", "coreTypeIds":"3", "damTypeIds":"8", "fedConstructionIds":"1", "fedDesignIds":"1;17", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Isabella Lake", "ownerNames":"USACE - Sacramento District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;2;5;6", "dsacId":4, "femaRegion":"9", "lastEapExcerDate":"2017-11-08T12:00:00.000Z", "dataUpdated":"2025-04-01T12:00:00.000Z", "usaceDistrict":"Sacramento District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"180300", "doi_region":"CGB", "doi_region_name":"California-Great Basin", "doi_region_number":10 }, "id":12183044, "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/12183044?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/12183044?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/12183044?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
