"politicalPartyId":null, "privateDamId":null, "projectDescription":"The Conchas Dam project is owned and operated by the Albuquerque District, U.S. Army Corps of Engineers (USACE). The project includes a dam located on the Canadian River in San Miguel County, New Mexico. Construction was completed in 1948 and primary project features include a combination concrete gravity dam with zoned earthen embankments; gated outlet works to adjust operational water releases into the Canadian River; gated irrigation headworks to allow controlled releases for irrigation demand; and two spillways to pass much larger, uncontrolled flows during extreme events. One spillway is a concrete weir located separate from the primary concrete and earthen dam and the other is integral to the concrete gravity dam. During flood events, the Conchas dam project can be operated for flood risk reduction on its own or in conjunction with other dams to optimize upstream and downstream flood risks within the Canadian River basin. In addition to the project\u2019s main purpose to provide flood risk reduction, it is also authorized for sediment retention, irrigation, and recreation benefits.", "riskCharSummary":"Although the Conchas Dam project has successfully reduced flooding, it does not eliminate all flood risk caused by rainfall downstream of the dam or due to emergency operation of the project. During infrequent emergency operations, larger required releases passing through the project\u2019s gated outlet works could surpass downstream river channel capacity and flood low-lying areas along the Canadian River to Ute Dam. Although the progression of events leading to much larger, uncontrolled spillway flow has never occurred, uncontrolled flow through the spillways would greatly surpass downstream channel capacity, flood low-lying areas along the Canadian River, and be life-threatening. Flood inundation caused by uncontrolled spillway flow could cause catastrophic downstream damages to residences and infrastructure (including State Highways 433 and 104) along the Canadian River to Ute Dam. \n\nA screening level risk assessment of the Conchas Dam project was completed in 2009. Preliminary results characterized dam breach risk as LOW due to the combination of life loss consequences and low likelihood of dam breach occurring either during normal operations or as the result of an extreme event. However, if a dam breach were to occur, flood inundation could be life-threatening and cause catastrophic downstream damages to residences and infrastructure (including State Highways 433 and 104) along the Canadian River to Ute Dam.", "riskManagementMeasures":"USACE strives to manage risk through application of several measures including inspections and instrument evaluations, maintenance activities, and risk communication. Routine inspections and instrument evaluation are performed to monitor performance of the project. Special inspections or increased inspection frequency occurs during high pools, spillway flows, or in response to earthquake or signs of distress. Comprehensive inspections occur annually, with more detailed inspections taking place every 5 years. Assessments occur every 10 years to compare original design and construction methods to modern standards. Maintenance is routinely performed at the project and recent activities include maintenance of mechanical equipment and sediment removal. Future risk communication activities include revisions to the Emergency Action Plan (EAP) and development of a formal risk communication plan.", "riverName":"CANADIAN RIVER/CONCHAS RIVER", "separateStructuresCount":0, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":3300, "stateFedId":"NM00006", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":235, "submitDate":"2021-05-28T12:00:00.000Z", "surfaceArea":2694, "volume":755000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1940, "congDist":"Congressional District 03, New Mexico", "city":"LOGAN", "county":"San Miguel", "aiannh":null, "websiteUrl":"https://www.spa.usace.army.mil/Missions/Civil-Works/Recreation/Conchas-Lake/", "coreTypeIds":"2", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":"1", "nonFederalDamOnFederalId":0, "designerNames":"CESPA", "otherNames":"Conchas Lake", "ownerNames":"USACE - Albuquerque District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":4, "femaRegion":"6", "lastEapExcerDate":"2025-06-04T12:00:00.000Z", "dataUpdated":"2025-06-04T12:00:00.000Z", "usaceDistrict":"Albuquerque District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"110800", "doi_region":"UCB", "doi_region_name":"Upper Colorado Basin", "doi_region_number":7, "thirtyYearAverage":218.0364, "tenthPercentile":98.3602, "ninetiethPercentile":361.654 }, "id":33043, "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/33043?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/33043?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/33043?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
