Moose Creek Dam is located southeast of the City of North Pole, Alaska, and approximately 15 miles east-southeast of the City of Fairbanks, Alaska. Since it went into operation, the dam has reduced damages caused by downstream flooding by an estimated $420 million. The dam does not typically retain water, however, when there is a large storm event, the dam gates are closed and water is purposely pooled in the floodway to prevent downstream damages. If the event is large enough, the water will travel the length of the floodway and discharge into the Tanana River. Besides flood control, the project also provides opportunities to enhance the environment for wildlife and is used for recreational purposes.", "riskCharSummary":"Although Moose Creek Dam reduces the risk of flooding to downstream communities, the dam does not eliminate the risk of flooding. When the dam impounds water, the groundwater in the community is usually elevated and low-lying areas are flooded, especially in the neighboring community of North Pole and the Steamboat Landing area along the Chena River. \n\nUnlikely scenarios that could result in devastating downstream flooding from Moose Creek Dam include an uncontrolled high-volume release of water due to erosion of the dam's foundation soils during significant rainfall and snowmelt events. Historically, the water behind the dam has never been higher than one third of the dam's height. It is uncertain how well the dam and its foundation soils will perform at higher levels. Lastly, devastating floodwaters from the Tanana River can reach the dam by flowing backwards through the floodway and into the Chena River. The Tanana River waters could cause similar catastrophic problems to the dam's foundation.\n\nIf the dam were to fail, an uncontrolled surge of water would flow out, flooding downstream communities. The City of North Pole is directly downstream of the dam and would be flooded, with little or no warning. Fort Wainwright and the City of Fairbanks, which are further downstream, would also experience extensive flooding, but are likely have greater warning times. \n\nAlthough very unlikely, a dam breach would result in downstream floodwater being swift and deep, destroying buildings and key infrastructure, and those caught unaware and/or unable to evacuate could perish.", "riskManagementMeasures":"USACE is taking multiple steps necessary to reduce risk to the public. First, USACE is designing ways to protect the dam's foundation from erosion. Additionally, USACE works closely with state and local emergency managers to conduct emergency exercises and to keep emergency action plans current. Annual inspections and regular maintenance are conducted to ensure the dam is functioning as intended. USACE rigorously monitors and surveys the dam, especially during high-water events. USACE also follows rainfall forecasts to predict when high-water events may occur, and to provide information for any necessary flood warnings to agency partners. Also, USACE works with local emergency managers to help residents understand how they can prepare for a flood.", "riverName":"CHENA RIVER", "separateStructuresCount":1, "sourceAgency":"US Army Corps of Engineers", "spillwayTypeId":3, "spillwayWidth":2000, "stateFedId":"AK00085", "stateRegulatoryAgency":null, "stateRegulatedId":0, "structuralHeight":60, "submitDate":"2023-02-16T17:25:23.299Z", "surfaceArea":1, "volume":0, "widthOfLocks":0, "secondaryWidthOfLocks":null, "yearCompleted":1979, "congDist":"Congressional District 00, Alaska", "city":"FAIRBANKS", "county":"Fairbanks North Star Borough", "aiannh":null, "websiteUrl":"https://www.usace.army.mil/Missions/Civil-Works/Dam-Safety-Program/Article/2870967/dam-safety-program/", "coreTypeIds":"3", "damTypeIds":"11;8", "fedConstructionIds":"1", "fedDesignIds":"1", "fedFundingIds":"1", "fedInspectionIds":"1", "fedOperationIds":"1", "fedOtherIds":null, "fedOwnerIds":"1", "fedRegulatoryIds":"1", "formerNames":null, "foundationTypeIds":null, "nonFederalDamOnFederalId":0, "designerNames":null, "otherNames":"Chena Lake", "ownerNames":"USACE - Alaska District", "ownerTypeIds":"3", "primaryDamTypeId":11, "primaryOwnerTypeId":3, "primaryPurposeId":9, "purposeIds":"9;5", "dsacId":3, "femaRegion":"10", "lastEapExcerDate":"2024-04-18T12:00:00.000Z", "dataUpdated":"2025-06-12T12:00:00.000Z", "usaceDistrict":"Alaska District", "noConsequencesId":0, "secretaryAgricultureBuiltId":null, "nrcsWatershedAuthorizationId":null, "isAssociatedStructureId":"No", "fedRegulatedId":"Yes", "inundationNidAddedId":1, "damStatusId":2, "huc06":"190803", "doi_region":null, "doi_region_name":"Alaska", "doi_region_number":11 }, "id":2796555126, "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/2796555126?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/2796555126?f=jsonld" }, { "rel":"alternate", "type":"text/html", "title":"This document as HTML", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr/items/2796555126?f=html" }, { "rel":"collection", "type":"application/json", "title":"USACE Access2Water API", "href":"https://api.wwdh.internetofwater.app/collections/usace-edr" } ] }
