States. 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":"USACE completed a risk assessment of Buffumville Dam in 2015 and has classified the risks associated with the dam as Low. The dam significantly reduces the risk of flooding to surrounding communities. However, it does not entirely eliminate the risk. The most likely scenario that could result in downstream flooding from Buffumville Dam would be an uncontrolled high volume release of water from the dam's spillway during significant storm events. The amount of water being released could be great enough to cause flooding in downstream communities. Such higher releases from the spillway could create conditions similar to how the river might behave during a flood event if the dam did not exist. \n\nThere is also an extremely unlikely, but far more devastating scenario that would result in failure of the dam or dike and downstream flooding: water seeping through the dam earth embankments results in voids in these structures as the soil erodes, potentially weakening the structures. This erosion could occur in the upper portion of the foundation soil, through the cutoff trench in the original river channel, or in the cutoff trench/bedrock interface and could lead to a breach Were any of these events to occur, an uncontrolled surge of water would flow out of the reservoir, flooding downstream communities. Oxford, Webster ,and Dudley, MA are the major areas in immediate danger in the event of the flood. Towns and cities further downstream in Massachusetts and Connecticut would also be impacted, but less so. \n\nEven though very unlikely, if any of the scenarios described above were to occur, the downstream floodwater would be swift and deep, destroying buildings and key infrastructure, and those caught unaware and/or unable to evacuate could perish. In the less likely dam breach scenarios, the water depth, property damage, and lives lost would likely be far greater than flooding due to spillway discharges.", "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.\n\nBuffumville Dam is operated in conjunction with Hodges Village Dam and is staffed daily. During set pool elevations, the dam is inspected daily by project staff. If the pool rises higher, engineers inspect the site as well. Instrumentation is monitored monthly at a minimum, and daily during high pools.", "riverName":"LITTLE RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":298, "stateFedId":"MA00964", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":66, "submitDate":"2023-02-16T17:25:17.665Z", "surfaceArea":200, "volume":350000, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1958, "congDist":"Congressional District 01, Massachusetts", "city":"WEBSTER", "county":"Worcester", "aiannh":null, "websiteUrl":"https://www.nae.usace.army.mil/Missions/Civil-Works/Flood-Risk-Management/Massachusetts/Buffumville/", "coreTypeIds":"1;3", "damTypeIds":"9;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":"1", "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":"Pierpoint Pond Dike", "foundationTypeIds":"1;3", "nonFederalDamOnFederalId":0, "designerNames":"CENAE", "otherNames":"Buffumville Lake", "ownerNames":"USACE - New England District", "ownerTypeIds":"3", "primaryDamTypeId":9, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9", "dsacId":4, "femaRegion":"1", "lastEapExcerDate":"2024-04-05T12:00:00.000Z", "dataUpdated":"2025-04-09T12:00:00.000Z", "usaceDistrict":"New England District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"011000", "doi_region":null, "doi_region_name":"North Atlantic-Appalachian", "doi_region_number":1 }, "id":8032021, "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/8032021?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/8032021?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/8032021?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
