"politicalPartyId":null, "privateDamId":null, "projectDescription":"The U.S. Army Corps of Engineers (USACE) built Black Butte Dam in 1963. Black Butte Dam is located on Stony Creek, about 9 miles northwest of Orland, California. The dam structure consists of an earthfill embankment and includes an ungated, earthen spillway channel located near the northern end of the dam. There is a hydropower facility located just downstream from the dam that is owned and operated by the City of Santa Clara under a license from the Federal Energy Regulatory Commission. Black Butte Dam reduces the risk of flooding primarily to the city of Orland 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 Black Butte Lake. Although flood risk management is the project\u2019s primary focus, the dam also provides irrigation, hydropower generation, recreation, and environmental stewardship benefits.", "riskCharSummary":"Black Butte 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 Black Butte Dam in 2008 to understand how the dam might perform during certain scenarios and found the likelihood of the dam overtopping or failing in those cases to be moderate. Factors that do pose some concern and that might cause flooding downstream of Black Butte Dam include the dam\u2019s spillway and earthquakes. A very rare and extreme flood event could cause the water level of Black Butte Lake to flow over the top of the dam. The earth spillway channel could also erode during high flows. In addition, an unlikely major earthquake could cause the soil in the dam and under the dam\u2019s foundation to temporarily move like a liquid, which can result in significant deformations and strength loss of the dam. The resulting deformations and strength loss can disrupt materials inside the dam. This in turn could initiate water seeping through the dam materials which could eventually lead to uncontrolled loss of water from the reservoir. If this were to occur when Black Butte Lake is at maximum capacity, the downstream communities will see significant flooding which could potentially result in loss of human life, economic impacts, and environmental damage. The population at risk includes portions of the cities of Orland, Hamilton, Butte and Colusa as well as rural population in the floodplain. Potentially impacted infrastructure includes road networks, electrical substations, communication facilities, police and fire stations, hospitals, airports, and schools. A large portion of farmland will also be impacted. Although these scenarios are considered extremely unlikely, there is an emergency action plan for Black Butte Dam 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 Black Butte 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. USACE performs regular inspections and instrument monitoring to ensure that the structure is performing as designed and could help detect any areas of potential concern. The frequency of these checks increases when Black Butte Lake rises. USACE incorporates weather forecasts to make informed decisions on how to operate the dam. The releases at Black Butte 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 a coordinated warning notification within minutes to hours depending on location before water reaches their homes. However, during very large and rare earthquake events, there may be little to no warning.", "riverName":"Stony Creek", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":118, "stateFedId":"CA10102", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":156, "submitDate":"2023-02-16T17:25:11.618Z", "surfaceArea":4560, "volume":0, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1963, "congDist":"Congressional District 01, California", "city":"ORLAND", "county":"Tehama", "aiannh":null, "websiteUrl":"https://www.spk.usace.army.mil/Missions/Recreation/Black-Butte-Lake/", "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":"Black Butte Lake", "ownerNames":"USACE - Sacramento District", "ownerTypeIds":"3", "primaryDamTypeId":8, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;2;5;6", "dsacId":3, "femaRegion":"9", "lastEapExcerDate":"2024-12-18T12:00:00.000Z", "dataUpdated":"2025-03-24T12:00:00.000Z", "usaceDistrict":"Sacramento District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"180201", "doi_region":"CGB", "doi_region_name":"California-Great Basin", "doi_region_number":10 }, "id":3975754044, "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/3975754044?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/3975754044?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/3975754044?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
