"politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) built Terminus Dam in 1962. The dam is located on the Kaweah River near Lemon Cove, CA approximately 20 miles northeast of Visalia, CA. Terminus Dam reduces the risk of flooding to the cities of Lemon Cove, Visalia, Tulare, and other nearby communities by holding back water during major flood events. In addition to reducing flooding downstream, the water held back by the dam forms Lake Kaweah. Although flood risk management is the project's primary focus, the dam also provides water supply, recreation, and environmental stewardship benefits to nearby communities. The dam structure is primarily an earthen embankment with a concrete spillway located to the left of the main dam. In addition to the main dam, there is an auxiliary dam south of the marina and a dike upstream in the reservoir that protects a hotel on Sierra Drive. The auxiliary dam protects the same communities as the main dam.", "riskCharSummary":"Terminus Dam has historically performed well and significantly reduces the risk of flooding to downstream communities. However, it does not fully eliminate the potential for downstream flooding. USACE completed a risk assessment for Terminus Dam in January of 2016 to understand how the dam might perform during certain scenarios and found the risk of the dam overtopping or failing in those cases to be low. Factors that do pose some concern and that might cause flooding downstream of the dam include extreme rainfall, snow melting in the Sierras, and earthquakes. A very large rainfall and snowmelt event with unusually large quantities of water could lead to larger than normal outflows of water through the dam and spillway. Even when the dam operates as intended, such a scenario could cause downstream flooding. In some scenarios, downstream levees near Tulare could be overtopped or impacted by large flows over the spillway. The most devastating potential scenario would occur if the dam were subjected to a large earthquake while the lake level was already high. In this unlikely event, an uncontrolled surge of water could flow out of the lake, resulting in potentially deadly flooding of Visalia, CA, and other agricultural downstream communities. Another potential scenario involves water seeping through the dam and carrying soil particles away from the part of the dam that meets the natural landscape when Lake Kaweah is at a higher elevation and portions of the dam are washed away. Although these scenarios are considered extremely unlikely, Terminus Dam has an emergency action plan to lower the risk of life loss if any of these scenarios occurred.", "riskManagementMeasures":"USACE works closely with local emergency managers, regularly updates the emergency action plan, and conducts emergency exercises with state, federal, and local partners, all of which help reduce risk to the public. USACE has full-time staff members who work at Terminus Dam. The staff performs regular maintenance and repairs as needed to keep the dam functioning properly and are available 24/7 to perform immediate inspections if an unusual event occurs. Regular inspections and instrument monitoring ensure that the structure is performing as designed and could help detect any areas of potential concern. The frequency of these checks increases when Lake Kaweah rises. USACE incorporates weather forecasts to make informed decisions on how to operate the dam. The releases at Terminus Dam are determined using the knowledge of local flows in the system and there may be situations where these localized flows change quickly and could affect the downstream communities. In most scenarios the downstream communities would have hours, or even days, from a coordinated warning notification before water reaches their homes. However, during very large and rare earthquake events, there may be little to no warning.", "riverName":"KAWEAH RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":307, "stateFedId":"CA10114", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":255, "submitDate":"2023-02-16T17:25:34.665Z", "surfaceArea":1945, "volume":0, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1962, "congDist":"Congressional District 20, California", "city":"LEMON COVE", "county":"Tulare", "aiannh":null, "websiteUrl":"https://www.spk.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/", "coreTypeIds":"3", "damTypeIds":"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":"Lake Kaweah", "ownerNames":"USACE - Sacramento District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;2;5;6", "dsacId":4, "femaRegion":"9", "lastEapExcerDate":"2024-09-18T12:00:00.000Z", "dataUpdated":"2025-04-03T12:00:00.000Z", "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":12186044, "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/12186044?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/12186044?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/12186044?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
